3 Red Hat/Microsoft Virtualization Collaboration Agenda Overview of the Cross Certification Agreement Foundational Points of the Agreement What has been certified to date Next Steps Running Red Hat Enterprise Linux on Microsoft Hyper-V John Kelbley, Microsoft Q&A

4 Red Hat/Microsoft Cross Certification Agreement Responding to Customers' Business needs Customers with heterogeneous environments demand full support Demand their vendors cooperate, irrespective of their competitive nature Joint support from prime OS vendors in the enterprise Agreed to cross-certify & demonstrate the commitment RHEL on Hyper-V Windows Server 2008 R2 on RHEV-H

5 Foundational Points of the Agreement Support from both Red Hat and Microsoft l Customers with valid support entitlements with both Red Hat and Microsoft can call either party for support for a certified configuration Ł Support teams will collaborate to resolve customer reported issues per customers' SLA agreement Both parties agree to resolve issues found with their respective products in a certified configuration

19 Agenda Overview Integration Services What are they? Installing Integration Services Red Hat on Hyper-V Q and A

20 What is an IS? IS = Integration Service (formerly called IC Integration Component) ISs enable a child OS instance to run better through enlightenment Enlightenments generally include: Synthetic Drivers Integration Services

21 ISs for Windows Enlightenments for Windows include: Synthetic Drivers IDE driver SCSI driver Network Drive Mouse Integration Video Integration Services Operating System Shutdown Time Synchronization Data Exchange Heartbeat Backup (VSS co-ordination)

22 What do you get for Linux? Enlightenments for Linux include (depending on version): Synthetic Drivers IDE driver SCSI driver Network Drive SMP Support (one to four virtual processors supported) Integration Services (shutdown, time sync, heartbeat) What s Missing? Console Mouse Integration (can get from Xen) Integration Services (data exchange and live backup)

23 The Announcement July 2009: Microsoft contributes driver code to Linux kernel Submitted under GPLv2 Since, 200+ patches received from Linux community December 2009: Linux ISs included in the staging tree of the kernel March 2010: Linux Integration Services v2.1 Beta Available

24 Linux Integration Services Functionality by Version VMBUS IDE Network SCSI V1 V2 Staging (deprecated) October, December, N/A X X ( ) X X ( ) X X ( ) X X ( ) SMP ( ) "Modinfo DRIVER" support ( ) Feature Date 2.1 Beta V2.1 March, 2010 X X X X June, 2010 X X X X X X X Shutdown X X TimeSync X X Heartbeat X

25 Reality Check: ISs NOT Required for Hyper-V Hyper-V device emulation works for nearly any operating systems (with less performance) Key hardware components are emulated: Video = S3 Trio64 SVGA like VESA Network = Intel / DEC Tulip 21x4x IDE Similar to that on Intel 440BX =

26 Agenda Overview Integration Services What are they? Installing Integration Services Red Hat on Hyper-V Q and A

27 Where To Get the ISs? V2/V2.1 (2008 and Hyper-V R2) available from I Linux kernel and newer, ISs may already be there n (if included by the distro - just enable) s t r No Integration Services package (yet) for u I S I S O F i

28 ReadMe for Linux ISs The Readme is a fantastic resource! Includes instructions for Installing ISs Upgrading V1 ICs to V2 / V2.1 ISs Guidance about issues and Best Practices (hda=noprobe hdb=noprobe) Static MAC addresses (use if VMs are live on HA Hyper-V!)

29 Console Mouse Integration Mouse work just fine, it just will not come out of scope automatically Use Ctrl-Alt-Left Arrow to release mouse Problem with chained RDP no mouse if you remote into Hyper-V host and access VM Use Hyper-V Console on local system instead Remote into VM instead! Linux servers often loaded without GUI (don t care about the mouse!) or accessed via remote X-Windows or VNC Can add mouse support after ICs via Xen site: (code is licensed under GPL) Doesn t work on all distros / versions

30 You also Need Linux! The following are supported by Microsoft: Red Hat Enterprise Linux 5.2, 5.3, 5.4, 5.5 x86 or x64 As well as SUSE Linux Enterprise Server 10 and 11 For the latest support info, check Must be sure to install Linux Source Code C compiler (building drivers!)

31 ISs Install on LOTS of Linux Distributions Microsoft DOES NOT SUPPORT other distributions, there s no company on the other end of the phone to call! Other distributions may be community supported Integration Services work with versions of Linux based on kernel release and newer

32 Tip Proxy Update Set network proxy as per s=&threadid=742 Create /etc/profile.d/proxy.sh export http_proxy= export ftp_proxy= export no_proxy=.domain.com export HTTP_PROXY= export FTP_PROXY= Create /etc/profile.d/proxy.csh setenv http_proxy setenv ftp_proxy setenv no_proxy.domain.com setenv HTTP_PROXY setenv FTP_PROXY

33 Installing the ISs is easy, if you have the right pieces!

34 Adding Required Components via Command Line Red Hat updates yum install kernel-devel yum groupinstall "development tools" yum update May need a restart

35 Adding Required Components via Command Line After the ISO is available mount /dev/cdrom /mnt mkdir /opt/linux_is cp r /mnt/* /opt/linux_is cd /opt/linux_is make make install (old process was to call perl setup.pl drivers instead of make)

36 Verifying Integration Services and Detecting Version Version 2.1 and newer support modinfo Let s you know the version of the Integration Services installed!

37 Agenda Overview Integration Services What are they? Installing Integration Services Red Hat on Hyper-V Q and A

38 Performance The Microsoft JIL is an interoperability lab (in Cambridge Mass.right across the river!) Interop should not come at the cost of performance We have ongoing performance characterization efforts around interop initiatives like virtualization Performance characterization is not benchmarking! Focused on Linux w/ Integration Services Emulated reference + functional

39 Tested Linux VM Configs Emulated NonHypervisor Aware OS Enlightened Linux Kernel Linux VSC Emulation VMBu s IO and network IO can be ~40% faster than experience emulated degradation compared Network ~30% better than emulated to metal Red Hat Certification for emulated

40 Migration (P2V) Fresh install is always best, but sometimes a Physical to Virtual (P2V) migration is required Lots of tools available - simplest way (I ve found) DD VHDTool 010/05/13/linux-p2v-with-dd-and-vhdtool-easyand-cheap.aspx

41 Benefits of RHEL on Hyper-V Consolidation (why most folks look at virtualization!) Management Backup and Recovery

42 Management Hyper-V uses a rich set of WMI-based APIs Great Open Source Hyper-V Management library available on CodePlex System Center suite (including System Center Virtual Machine Manager - SCVMM) Does LOTS more!

43 Virtualization Management With System Center Live host level virtual machine backup In guest consistency Rapid recovery Virtual machine management Server consolidation and resource utilization optimization Conversions: P2V and V2V End to end service management Server and application health monitoring & management Performance reporting and analysis Patch management and deployment OS and application configuration management Software upgrades

44 Monitoring Linux with System Center System Center Operations Manage (SCOM) has the capability to monitor RHEL: Monitoring Linux Using SCOM 2007 R2http://blogs.technet.com/b/birojitn/archive/2010/01/20/monitoringlinux-using-scom-2007-r2.aspx Introduction to the Red Hat Enterprise Linux Management Pack

45 Backup and Recovery Linux backup a challenge for Windows admins (new agents / processes) Hyper-V can facilitate backup & recovery DPM (or WSB, or a batch file with Xcopy) easier and almost always costs less than other enterprise backup solutions VM can be restored to exact point in time of backup Linux VMs backed up using parent VSS VMs saved during backup VM paused and memory saved to disk Snapshot taken on parent VM resumed

46 Virtualization Backup Virtual Machine1 Virtual Machine 2 Virtual Machine 3 Virtual Machine 4

47 Virtualization Backup non-vss Aware Guest OS Virtual Machine1 Windows 2000 Virtual Machine 2 For any OS or application that is not internally VSSaware (like Linux): Hibernate OS to save memory to disk Snap with VSS Resume OS

50 Next Steps - Microsoft Continue to drive the acceptance of synthetic drivers and related Integration Services Desired for improved performance of RHEL guests in Hyper-V
