1 Nitin V. Choudhari, Page 1 of 25 Virtual Machines I am presenting equally technical as well as usage of the best implemented scientific concept of Virtualization for E-Gov Projects through Virtual Machine. Basic concept of Virtual Machine is running multiple Operating Systems (including client as well as server) at a time simultaneously on single Computer. I have used this concept of Virtual Machine particularly for client Server based Land Record Computerization project related applications like LMIS, Agri Census, e- Chawdi and 7/12 data uploading on website. Basically in order to optimize and effective use of the Hardware/Software Resources and technical efforts and exercises to achieve goal in targeted time configured Virtual Machine of Red Had Linux Server 7.2 and Windows Client on the same computer system running simultaneously at a time and then by copying readily tested Virtual Machines to Large Number of Machines between host servers,on Various Old, New Computer System and Laptops, for saving the Server hardware Cost per location, backup and Disaster Recopy, Easy and quick Testing and R & D, new effortless deployments and basic system administration tasks and get the Client Server based E-Gov. activities through minimum trained staff. By running Linux Server and Windows Client simultaneously on Single Computer, Server Hardware cost for 7/12 and Property Card per LRC location at District and Tahsil (Block) level is saved. Implemented Virtual Machines for LRC from around ten years for testing, entry of 7/12 and Property Card. Used Virtual Machines to simply backups, disaster recovery, new deployments and basic system administration tasks and get the Client Server based E-Gov activities through minimum trained staff. Secured ftp server configured and Ready Usable Virtual Machines of Red Hat Linux Server 7.2, Windows XP client for 7/12 RCIS, Property Card (PCIS), Windows XP and Windows 7 Ultimate X 64 and Windows 8 Professional with common usable software s like MS Office, Adobe Acrobat reader, Printer Configured etc,

2 Nitin V. Choudhari, Page 2 of 25 kept on NIC Akola s secured ftp servers , user: nicakolaftp password: ******** accessible on NIC network. Districts in Maharashtra have downloaded Virtual Machines and using it smoothly and saved Server Hardware cost per location with optimal use of hardware software resources with minimal technical efforts and exercises. I want to share my practical experience of scientific analysis and findings as below which hoped to be useful for proper technical Usage and E-Gov implementation. Project Details are available on the District Website of Akola Titled as Virtual Machine : NIC Akola in E-Governance menu, with the link Virtual Machine: The original meaning of Virtual Machine, sometime called hardware Virtual Machine is that number of discrete identical execution of environments (instances) on a single computer, each of which runs an Operating System(OS). Basic use of Virtual Machine is running multiple Operating Systems at a time Simultaneously on single computer System. Virtual Machine Logically divide the single Computer System and resources into several isolated different sizes same like the slices of the bread each of which works and feels as a separate computer System / Server of different client / server Operating System and simultaneously run different isolated processes. More than one instance of that operating system run on the same hardware at the same time Another operating system can run in that simulated hardware

3 Nitin V. Choudhari, Page 3 of 25 More than one different operating system can share the same hardware at the same time Virtual Machine Operating System creates illusion of multiple processors Each capable of executing independently No sharing, except via network protocols Host Operating System: The operating system actually running on the hardware Together with virtualization layer, it simulates environment for Guest Operating System: The operating system running in the simulated environment Virtual-machine concept provides complete protection of system resources Each virtual machine is isolated from all other virtual machines. Isolation ensures that applications and services that run within a VM cannot interfere with the host OS or other VMs Therefore its one use is for the isolation of processes with specific resources so that the processes should not collide and affect each other. The resources of the physical computer are shared to create the virtual machines under which CPU scheduling can create the appearance that each user has own processor Spooling and a file system provide virtual card readers, virtual line printers Disk partitioned to provide virtual disks A normal user time-sharing terminal serves as the virtual machine operator s console

4 Nitin V. Choudhari, Page 4 of 25 Fig: Logical Structure of Virtual Machine By using the virtual machine Software we can install the new operating system as guest or we can configure and run the preexisting operating system in dual boot mode, as guest operating System. We can form Network connections between Virtual Machines using single Network card. We can assign different IP addresses to Different Virtual Machine using a single Network Card. Features and Findings on use of Virtual Machine, R & D and Scientific Analysis 1. Application Isolation: We run multiple applications at a time simultaneously on multiple Operating Systems running on Virtual Machine, isolated from each other so that the execution of each other does not affects to one another. Practically I used it like using multiple computer Systems at a time by using a single computer System using Virtual Machine.

5 Nitin V. Choudhari, Page 5 of 25 For Example: For Land Record Computerization I have created multiple Linux server on virtual machine on different computer systems along with the windows Client of the same system and can run 7/12 Data Conversion utility and Data uploading on District web site of multiple n number of Tahsils using less than n Physical Computer systems or even with a single physical computer system which contains virtual machines of Red Had 7.2 Linux Server and Windows Client. This task executed isolated to other applications so that both the process not affected by the execution of each other. I set different IP addresses for the Host and different Virtual machines as well as shared the single IP addresses for the host and multiple virtual machines as per the need and requirements of the application. 2. Setting Up distinct isolated Client/ Server Operating System on the Single Computer System: At the same time one can use the one computer system as a client and /or server of different Operating System. So this way we can run client and server system using single Machine. This is practically very useful when we have to do the data entry on client and server Environment at large number of distinct locations and where the server is just required as a background service. Under such situation we can install the client and server on single system and process the work and this way save the cost of the server hardware per every location. I have practically use this concept in Land Record Computerization in District Chandrapur, Maharashtra in 2002, where it is needed to process the data entry of LRC in 14 different Tahsils of District Chandrapur. I found it very beneficial by using the client system as Windows XP Operating System with Database as DB2 Personal Edition 7.2 and Server as Linux 7.2 server Operating System with Database server as DB2 7.2 in background

6 Nitin V. Choudhari, Page 6 of 25 running simultaneously at a time using Virtual Machines, on the single Computer System. 3. Faster Booting and processing: Another advantage is that booting and restarting a virtual machine can be much faster than with physical machine, since it may be possible to skip tasks such as hardware initialization. 4. Imagination to Guest VM as a Physical Server Hardware: Typically, guest operating systems and programs are not aware that they are running on a virtual platform and, as long as the VM's virtual platform is supported, this software can be installed in the same way it would be deployed to physical server hardware. 5. Useful for Testing and R & Purposes under Client Server Environment : Instead of practically visiting to client and server for testing I used Virtual Machines to switch for testing between client and server on the single computer system using. We can mount the drives and disks between the Virtual Machines and share data and resources. This way it is quite useful for Testing and R & D Purposes. 6. VMs can also be easily moved, copied, and reassigned between host servers to optimize hardware resource utilization. Also We can change the shared Hardware configuration settings allotted to the Virtual Machine as per the need and requirements. Virtual Machine HDD file is just like a image of Operating System/ Partition including all the software and setting installed on that Operating System / Partition. Its just like a mirror Image/ Ghost / Clone of the operating System/ Partition. Therefore by just copy paste and using, we need not have to install the OS, Application Software s and do exercising of setting configuring the software s and applications with each other. This

7 Nitin V. Choudhari, Page 7 of 25 is very useful in the case of complicated sophisticated software s. It save the efforts of setting and configuring. In order to optimize and effective use of the Hardware/Software Resources and technical efforts and exercises to achieve the goal in targeted time, I configured Virtual Machine of Red Had Linux Server and Windows Client on the same computer system running simultaneously at a time and then by copying readily tested Virtual Machines to Large Number of Machines between host servers,on Various Old, New Computer System and Laptops, for saving the Server hardware Cost per location. 7. Useful for Backups and Disaster Recovery: Administrators can also take advantage of virtual environments to simply backups, disaster recovery, new deployments and basic system administration tasks Used Virtual Machines of Red Hat Linux Server and Windows Client for the Backup and Recovery of Whole Operating System including Data, Application Softwars with Newtwork and Database Connection. As when we copies Virtual Operating System to another Computer, Drives it can be used directly as an when required and used as backup and recovery of the complete Operating System. In case any Host OS or Guest VM Client or Server OS fails, then whole software s, Network, Database connections and data lost and causes heavy unrecoverable disaster. This is resolved by copying/backup whole VM of Windows client as well as RH Linux Server on another System, Drives which later on can be directly copy and use as an when required with all software s, Network, Database connections and data as Disaster recovery and backup. 8. Virtual Machines are very useful to Optimize the Technical efforts and exercises, under the situation where a typical complex sophisticated application software is to be used at

8 Nitin V. Choudhari, Page 8 of 25 large number of Distinct locations., to achieve the output target within less time with optimal use of the Hardware / software and resources. Virtual Machine are very much useful when a typical Complex application which require various supporting front end and backend software compatible with each other with sophisticated setting and configurations with Database and network connections, is to be used at Discrete Distinct locations with various types of hardware software. Under such situation such application can be released in the form of Virtual Machine containing Operating System with Application software working along with all the necessary supporting software and setting, by which the users at Discrete Distinct locations gets the directly operational Application software along with the Operating System and all supporting software s with ready configured setting, Data base and network connections. This way the complex sophisticated technical efforts / exercises per discrete Distinct location can be saved by using Virtual Machine with optimal use of the Hardware / software and resources. This reduces the exercise of training to the user on sophisticated technologies and we can get the task completed easily through the less technical human resources. In the practical experience of use of Agri Census Data and Agri Census Data Conversion utility, around one month time of District unit Officials of 35 Districts was passed in the attempts to make the Agri Census Data utility operational and even after that very few succeeded with full of non uniformity. Instead if the same working operational Agri Census Application with the Data Conversion utility may have been released though ftp server in the form of Virtual Machine along with all the supporting software and settings configured, then it may have definitely saved the time and technical efforts and exercise of the District Unit Officials of 35

9 Nitin V. Choudhari, Page 9 of 25 District, and the specified task may have been achieved within very less time with minimal technical efforts by just replicating the working virtual machine on computer systems. The same technique I have used for the same purpose in Akola. I have made the application operational on one Computer System in the form of Virtual Machine and then replicated it on the computer Systems of all the Tahsils. 9. Import and Export Virtual Machine: We can Import / Export Virtual Machines between the various virtual machine software s like Windows Virtual Machine Mode and VMware. 10. It is very useful to run the Application on the Computer System which contains the non supporting host Operating System. Under this situation we can get the same application running and operational by installing the supporting guest Operating Installed using the Virtual Machine. In case of Land Record 7/12 Data uploading on District Website, the 7/12 Data conversion and uploading utility requires the Computer System with 4GB of RAM, and having Operating System Windows XP /Windows 7. I am not having any such computer System with 4 GB of RAM on any Windows XP / Windows 7 Client Computer System. But having Dell PowerEdge R715 Rack Mounting Server with 32GB of RAM with Windows Server 2008 Operating System. I have installed two separate Virtual Machines, of Windows XP and Red Hat Linux 7.2 Operating System along with all the necessary supporting software s and made the 7/12 Data Conversion utility operational on Dell Rack Mounting server and uploaded 7/12 Data on District Website by configuring client and server running simultaneously at a time on the same computer system It is found that while installing Red Hat Linux 7.2 on the Latest present Computer System, it is very difficult to install and

10 Nitin V. Choudhari, Page 10 of 25 xconfigurate ( Graphics Mode ) and nearly impossible, but the Red Hat 7.2 Linux Virtual Machines along with supporting IBM Db2 software and database, working on the another Computer Systems can be easily copied and working smoothly on the Latest Present Computer Systems in text mode which is sufficient to achieve our aim of running Red Hat 7.2 Linux server in Background. 11. Virtual Machines of Windows 7 X64 Ultimate and Windows 8 Pro X 64. The earlier Virtual Machine Software VMware-workstation-full used for Virtual Machines of Operating System Upto Windows 7 is not supporting to develop the Windows 8 Operating System Virtual Machine. The Latest VMware-workstation-full is supporting for the creation of Virtual Machine of Windows 8 Operating System. Also for Virtual Machine of Windows 8 Operating and Creation is not supported by the earlier Old Computers and requires the Virtualization Technology (VT) should be enabled through the BIOS setup on Motherboard. Downloading Virtual Machine Software s : The well known Virtual Machine Software VMWARE are available for downloading on site. And the same Microsoft Virtual Machine Software s can be feely downloaded from the Microsoft website. Achievements of Using Virtual Machine 1. Running distinct isolated Red Hat Linux Server and Windows Clients simultaneously on the Single Computer System for Land Records Computerization (LRC) by using basic concept of Virtual Machine of running multiple Operating Systems at a time Simultaneously on single computer System. 2. By running the Linux Server and Windows Client simultaneously on Single Computer System, Server Hardware cost ( Average

11 Nitin V. Choudhari, Page 11 of 25 Cost Rs. 50 Thousand per server) for 7/12 and Property Card per Tahsil location is saved. 3. As Virtual Machines can be easily moved, copied and reassigned between host servers, it s used to optimize hardware/software resource utilization with Minimal Technical efforts and exercises. Used 7/12 and property card Client, Server Virtual Machines to use a typical complex sophisticated application at large number of Distinct Tahsil locations by Optimizing Technical efforts and exercises, and achieved 7/12 and property card Data uploading on website and Agri Census work within time. 4. Useful for Backups and Disaster Recovery: used advantage of virtual environments to simply backups, disaster recovery, new deployments and basic system administration tasks. Used Virtual Machines of Red Hat Linux Server and Windows Client for the Backup and Recovery of Whole Operating System including Data, Application Softwars with Newtwork and Database Connection. As when we copies Virtual Operating System to another Computer, Drives it can be used directly as an when required and used as backup and recovery of the complete Operating System. In case any Host OS or Guest VM Client or Server OS fails, then whole software s, Network, Database connections and data lost and causes heavy unrecoverable disaster. This is resolved by copying/backup whole VM of Windows client as well as RH Linux Server on another System, Drives which later on can be directly copy and use as an when required with all software s, Network, Database connections and data as Disaster recovery and backup. 5. Secured ftp server configured and Ready Usable Virtual Machines of Red Hat Linux Server 7.2, Windows XP client for 7/12 RCIS, Property Card (PCIS) kept on NIC Akola s

12 Nitin V. Choudhari, Page 12 of 25 ftp server user: nicakolaftp password: ********* accessible on NIC network. 15 Districts in Maharashtra have downloaded Virtual Machines and using it smoothly and server Hardware cost per location with optimal use of hardware software resources with minimal technical efforts and exercises. Major challenges faced while implementing Virtual Machines and how they were overcome 1. Optimization of Hardware Software, Hardware resources and Technical exercises : Red Linux Server and Windows Client of Single Computer Running Simultaneously : Instead of using separate clients and server, installed Red Hat Linux Server and Windows Client on the single Computer using Virtual Machines running simultaneously. In around 2002 there are less Hardware resources and therefore for testing, support and data entry purposes it finds difficult to use separate Server,clients and it finds difficult for moving between clients and server. This is resolved by installing Red Hat Linux 7.2 Server using Virtual Machine software as Guest Operating System on Windows client as Host Operating System and both Windows Client and Red Hat Linux 7.2 server running simultaneously on single client computer system. 2. Saved Server Hardware per LRC location : Developed readily distributable Virtual Machine and replicated to number of SLR, TILR, SDO and Tahsildar Offices in Akola District and in around 15 Districts in the state by configuring secured ftp server of NIC, Akola. This way saved server hardware per location and optimized technical exercise for easy testing, backup and Disaster recovery of complete operating System including application software s, data, Network and Database connections. In order to

13 Nitin V. Choudhari, Page 13 of 25 save server Hardware, it s needed to deploy VM s of Client, Server on various locations at District HQ and Tahsil s in Land Records SLR, TILR, SDO and Tahsildar Offices. This is resolved by developing uniform readily distributable VM s of Windows client and RH Linux 7.2 server for 7/12 and property card, and by coping it, multiples required clients and servers created to complete entry of 7/12 and Property card in less time at LRC locations at District HQ and Tahsil. 3. Completion of work in optimum time :Entry, updating and validation and processing of the 7/12 and Property card completed in quick time by creating large number of client and servers just by replicating readily Distributable Virtual Machines of Red Hat Linux Server and Windows Client. 4. Backup and Disaster Recovery: Used Virtual Machines of Red Hat Linux Server and Windows Client for the Backup and Recovery of Whole Operating System including Data, Application Softwars with Newtwork and Database Connection. As when we copies Virtual Operating System to another Computer, Drives it can be used directly as an when required and used as backup and recovery of the complete Operating System. In case any Host OS or Guest VM Client or Server OS fails, then whole software s, Network, Database connections and data lost and causes heavy unrecoverable disaster. This is resolved by copying/backup whole VM of Windows client as well as RH Linux Server on another System, Drives which later on can be directly copy and use as an when required with all software s, Network, Database connections and data as Disaster recovery and backup. 5. Running Application on Non Supporting Host Operating System by installing supporting OS as Guest using Virtual Machine. For hosting LRC data on District Web Site, needs System

14 Nitin V. Choudhari, Page 14 of 25 with 4GB RAM and OS Win XP / 7 was not available with NIC. Used VM on system having non supporting Win Server 2008 OS with 32GB RAM and installed Windows XP VM and RH Linux Server as Guest and installed LRC data hosting utility and a hosted LRC data on District web site using single system containing client & server. 6. Running Red Hat Linux Server for LRC on various non supporting old, new systems and Laptops by copying readily Distributable Red Hat Linux 7.2 Virtual Machine. Latest hardware is not supported by the Red Hat Linux 7.2, developed readily distributable VM s of RH Linux 7.2 and Windows XP client and used independent to Hardware on various old, new Systems and Laptops for LRC locations in Akola and used by other 15 Districts through NIC Akola s ftp server. In the present age New hardware is not supported by the Red Hat Linux 7.2 and therefore it is nearly found impossible to install the Red Hat Linux Server for Land Record Computerization 7/12 as well as for property card on the present new computer systems. Therefore the users are compelled to use only the old outdated obsolete computer systems for the LRC Red Hat 7.2 Linux server, whose availability, functionality and support are the very problematic now a days. In the LRC conference/ workshop on 5 th Oct 2012 at Yashda, Pune several District Representatives has raised the issues to Settlement Commissioner, of unable to install the Red Hat Linux Server on the New Computer Systems and the Solution given by NIC, LRC team Pune is to hire the old Computer System temporarily and get the Red Hat Linux 7.2 server installed on it. This challenge is resolved by me very easily by copying and Deploying the Readily Distributable Lab tested Red Hat Linux Server Virtual Machines on the all the New Computer Systems including Laptops, as well as Old Computer Systems and Old

15 Nitin V. Choudhari, Page 15 of 25 Laptops. The same Readily Distributable copy and movable Virtual Machines of Windows Client and Red Hat Linux Server are implemented in Akola District for Land Record Computerization in District Head Quarter Superintend of Land Records offices and at Division and Tahsil level in SDO and Tahsildar and TILR offices on various New and Old Computer Systems. The secured ftp server is configured and Ready Usable Virtual Machines of Red Hat Linux Server 7.2 and Windows XP client for the 7/12 RCIS and Property Card (PCIS) are kept on the NIC Akola s ftp server user name: nicftpakola password: ******** accessible on NIC NICNET network only. The various around 15 Districts in Maharashtra including Akola, Namely Washim, Buldhana, Beed, Hingoli, Wardha, Nandubar, Parbhani, Amaravati, Nagpur, Ratnagiri, Thane, Chadrapur, Osmanabad and Raigad, have downloaded the Ready Virtual Machines and using it smoothly by saving the server Hardware cost per location with minimal use of hardware software resources with minimal technical efforts and exercises. Project / initiative with Methodology adopted for Particular Purposes. The 7/12 Software Land Management Information System (LMIS) and Property Card Software Property Card Information System (PCIS) is working with Server Computer System as Red Hat Linux 7.2 as Server Operating System, IBM Db2 7.2 Server as DBMS containing Databases for rcis ( 7/12 abstract information sytem ) and pcis ( Property Card Information System ), and Client Computer System as Windows 2000/Windows XP SP2 as

16 Nitin V. Choudhari, Page 16 of 25 Operating System, IBM Db2 7.2 Personnel Edition as DBMS and LRC 7/12 and / Or Property Card Application Software s developed by NIC Software Development Unit, Pune. Earlier in Around at NIC, Chandrapur (Maharashtra ), I have used Virtual Machines of Same LRC Red Hat Linux Server 7.2 and Windows 2000 and Windows XP Clients installed on the single computer System by using VMware Workstation 3.0 at that time for the testing and Data entry purposes and saved the server Hardware cost per location. For Land Records 7/12 and Property Card Data Conversion to Unicode and Uploading on District Web Site In Around Sep 2011 we have to upload the 7/12 and Property Card Data every month on District web site for this purpose the process involved are first exporting Data from IBM Db2 to SQL Server and then conversion of SQL Data to Unicode and then uploading of the Data to District Website. For all the operations NIC, Software Development, Pune has provided the utilities which requires SQL Server 2008 on Windows XP/ Windows 7 and other Software with Computer System having minimum 4 GB of RAM for processing of Data from Linux Server to Local SQL Server and then from Local SQL Server to Remote SQL Server of web site. We were not having at all any Desktop Computer System with 4 GB of RAM. The Computer Systems with Windows XP Computer Systems are with just 1 GB of RAM. Just one DIO Dell E5400 Laptop that too having only 2 GB of RAM. First we have Attempted on it but unable to process it properly due to the limited RAM and other hardware software resources of LAPTOP. We ware facing the problem for the availability of the Computer System for the Red Hat Linux Server. Also the New Computer System hardware is not supporting to Red Hat Linux Server 7.2

17 Nitin V. Choudhari, Page 17 of 25 and therefore it requires old Hardware only availability of which was not there and very difficult. But we have Dell PowerEdge R715 Rack Mounting Server with 32GB of RAM with again non supporting Windows Server 2008 Operating System. Using Dell PowerEdge R715 Rack Mounting Server with 32GB of RAM and Win Server 2008 as Host Operating System using the earlier experience of uses of Virtual Machines, I have developed Virtual Machine of Red Hat Linux Server 7.2 with IBM Db2 7.2 DBMS Server database as Guest Operating System using VMware-workstation-full The Virtual Machine of Red Hat Linux with IBM Db2 7.2 DBMS containing LRC rcis (Database for 7/12 records of Right information System ) and pcis ( Property Card Information System ) databases is used as LRC Server. Earlier in around at while working at NIC, Chandrapur, Maharashtra, we have not faced much difficulties while installing Red Hat Linux Virtual Machine as Guest Operating System on the old hardware compatible to Red Hat Linux at that time. But while installing the Virtual Machine of Red Hat Linux directly as well as Virtual Machine of the present Computer Systems we have faced tremendous Problems and Challenges. As the Hardware of the new Computer Systems not supporting to Red Hat Linux 7.2, while attempting it directly as Host Operating System, after initial setup steps it comes out directly with system panic due to various hardware compatibility issues and found its nearly impossible to install it as host Operating System. Therefore the only way remains with us to is either to use the old Hardware which is not available as well as maintenance issues or Switch over and attempt to Develop the Virtual Machine of Red Hat Linux 7.2 as Guest on Windows Operating System as host. While attempting for installing Virtual Machine of Red Hat Linux 7.2 as guest on present

18 Nitin V. Choudhari, Page 18 of 25 Hardware Computer Systems Dell PowerEdge R715 Rack Mounting Server with AMD Processor, Other New Systems and Laptops with Intel Core2 Due,i3,i5 processors also we have faced tremendous difficulties particularly with the Graphics/ Display cards related issues with the control come out from installation with system panic and we fail around six to seven attempts with alternative trials every time and Finally we succeeded it first on Dell PowerEdge R715 Rack Mounting Server, and then on Other New Systems and Laptops with Intel Core2 Due,i3,i5 processors with the latest Graphics cards also, with commonly selecting a Graphic Card as S3 Verge Trio V64 Generic. Also we have developed the Same Virtual Machine of Red Hat Linux as Guest Operating System on the Old P4 Clients also if face any problem with the other Virtual Machine which we have not faced at all. On the same Dell PowerEdge R715 Rack Mounting Server with 32GB of RAM and Win Server 2008 as Host Operating System we have developed Virtual Machine of Windows XP SP2 with IBM Db2 7.2 Personnel edition as another Guest Operating System using VMware-workstation-full Established the Connectivity between the Red Hat Linux Server and Windows XP Client using, Bridged: Connected Directly to the Physical Network, Networking, with both Server and Client Operating Systems on the Single Computer System Dell Rack Mounting Server. On the Guest Windows XP Client Virtual Machine on Dell Rack Mounting Server installed the SQL Server 2008 and Other Supporting Software and Utility provided by NIC, SDU, Pune of Exporting IBM Db2 Data from Red Hat Linux Server to Windows SQL Server, Data Conversion from SQL to Unicode, Exporting / uploading Unicode Converted LRC 7/12 / pcis Data to Local SQL Server and Remote web site SQL server.

19 Nitin V. Choudhari, Page 19 of 25 Using the Sophisticated setup of Red Hat Linux Server Virtual Machine, Windows XP SP2 Virtual Machine with the Unicode Data Conversion and Uploading Utilities on the single Dell PowerEdge 715 Rack Mounting Server, we have successfully uploaded the 7/12 as well as property Card Data of all the Tahsil / Talukas every month on NIC District Akola website. We have replicated all these Virtual Machines on the same Dell PowerEdge 715 Rack Mounting Server and used the High Configuration of it, to upload the LRC 7/12 and or Property Card Data of Multiple Tahsils at a time on NIC District Akola website every month, timely within the specified time limits to provide the instant Public Service Delivery of 7/12 and Property Cards to citizens. Later on after around more than six months we have received Two Computer System With 4 GB of RAM but again non supporting Operating System Windows 7. Instead of Installing anything New we have just installed Virtual Machine Software VMwareworkstation-full and replicated all the ready made Virtual Machines of Red Hat Linux Server, Windows XP Sp2 Client will all Unicode Data Conversion and Uploading to Website, installed on Dell PowerEdge 715 Rack Mounting Server to these Newly received Computer System and used these newly received computer Systems Directly for LRC 7/12 and property card Data Unicode conversion and uploading every month to NIC District Unit Akola website, with minimum technical efforts, exercises and Hardware software resources, to provide the timely Public Service Delivery of 7/12 and Property Cards to citizens. The Uploading the 7/12 and Property Card data is still Operational using the same Virtual Machines and Host Systems. For Agri Census.

20 Nitin V. Choudhari, Page 20 of 25 The Agricultural Census Computerization work is started from Jan In Dec 2012 just the initial idea of the Agri Census Application was demonstrated through VC. The Acri Census Work is also closely related to Land Records Data and Computerization. It also used 7/12 Unicode converted Data. 7/12 Date from IBM Db2 7.2 exported to Postgre SQL and then converted to Unicode using Utility Application developed by SDU, Pune. The overall process is so sophisticated that almost most of the District unit takes a month to make it operational due to varieties of System and Applications software s and versions compatibility issues with each otter. Again we have used the same concept of Virtual Machines. As this time we have already Virtual Machines of Red Hat Linux and Windows Client Available. We have made the Agri Census Applications operational on Windows XP SP2 Virtual Machine as guest on the Single Computer System and then replicated just within a hour as Virtual Machine of Guest Windows XP Operating system on the Computer Systems to be used for Tahsils by the BOT vendors and completed our work in the specified time limit given 19 Jan Background of Need/Demand for Developing ready Distributable LRC Virtual Machine of Red Hat Linux Server 7.2 There was Meeting Hosted by Settlement Commissioner and Director of Land Records (SC & DLR), Pune with all the District Informatics Officers (DIO s) & District Domain Expert (DDE s) from the Districts of Maharashtra for Land Record Computerization (LRC) National Land Records Modernization Program ( NLRMP) at Yashada, Pune on 05 Oct During the Meeting the issue raised by the several Districts regarding the inability of installation of Red Hat Linux server on New Computer Systems with Core 2 Duo, i3, i5 processors and latest graphics, Non Availability of the Compatible Server Hardware for the Red Hat Linux Server as the

21 Nitin V. Choudhari, Page 21 of 25 unavailability of the Old Computer Systems which is Compatible with Red Hat Linux and incompatibility of the new Hardware with the Red Hat Linux Server. But no satisfactory solution is provided to them with the advice to avail the Old Server Hardware on rental basis which is nearly very much difficult with the several maintenance problems to maintain the live Land Records project 7/12 and property Card public delivery services. egov Workshop on 21, 22 Nov at Yashada, Pune. DIT Govt of Maharashtra has hosted a tow day workshop on sharing of best practices in e_governace at Yashada, Pune on 20 th and 21 st Nov In this workshop on 21 st Nov 2012, presented the research and Analysis papers on Virtual Machines and the concept and analysis and use is very much appreciated by Shri Rajesh Agrawal, Secretary DIT, Govt. Of Maharashtra and advised all the officials to Implement the same concept of Virtual Machine in the state instead of Purchasing the New Servers for Land Records. Developed Readily Distributable VM s and Distributed to Districts of Maharashtra through Secured ftp server. Looking into the problem with the compatibility issue of Red Hat Linux with New Hardware faced by the Districts of Maharashtra. Configured and developed and customized the Virtual Machines of Red Hat Linux Server and Windows client for LRC with all the necessary software applications, facility and LRC 7/12 ( LMIS ) and Property card PCIS applications so that they can be commonly used in the state by just copying. The Virtual Machines of Windows XP with General Common Applications software is also developed. Smooth working of All the Virtual Machines are tested on Old, New Computer Systems and Laptops is tested. The readily distributed Virtual Machines are tested on Demand with the neighboring Districts Washim and Buldhana and found working smoothly with

22 Nitin V. Choudhari, Page 22 of 25 the perfect expected results with the saving of server hardware of Red Hat Linux per location. The availability of the readily Distributable Virtual Machines is informed to the NIC District Units of Maharashtra and to all the concerns of the LRC project with request to allow to host these readily Distributed Virtual Machine on State Data Centre / Data Centre of SDU, Pune but not received sufficient response for hosting the Virtual Machines. Therefore the Secured Microsoft FTP Server is configured with ip address user name: nicakolaftp and Password: ******** and Hosted all the Readily Distributable Virtual Machine of LRC Red Hat Linux Server and Windows Client as well as Virtual Machines of Windows with common Applications, and informed for downloading and use, to the NIC District Units of Maharashtra and to all the concerns of the LRC project. The NIC District Units of Maharashtra has downloaded these Readily Distributable LRC Virtual Machines and using at the required LRC Property Card and 7/12 locations at District Level, SDO level, Tahsildar and Taluka Inspector of Land Records (TILR ) offices. The Same Virtual Machines of Land Records are implemented for all the Property Card Locations in the District Akola at District and TILR Offices, due to unavailability of the server Hardware and this way the server hardware cost per location is saved with minimal technical efforts and exercises, less technical human resource with optimum use of the software and hardware. The implementation of LRC Virtual Machines of Server and Client in the Districts of Maharashtra with the server hardware cost per location is saved with minimal technical efforts and exercises, less technical human resource with optimum use of the software and hardware, is presented in the Video Conferencing Session on 6 th
