2 Introduction Nico Schottelius President of ungleich GmbH Linux/Unix Infrastructure Services Application Hosting (RubyOnRails, Django, Nodejs) Hosting based on OpenNebula and cdist FOSS Hacker

3 I talk for you Ask Questions Any Time I answers in <30s

4 Overview Introduction OpenNebula Basics How to Setup How to Use Advanced topics High Availability Clusters & Federation Follow Up / Questions

5 What is OpenNebula?

6 What is OpenNebula? OpenNebula is a powerful, proven, adaptable and interoperable open-source platform for data center virtualization and enterprise cloud management, which is certified and commercially supported on the most common infrastructure platforms. OpenNebula provides the rapid innovation of open-source, with stability and long-term production support of commercial software.

7 What is OpenNebula? Open Source Software Virtualisation Plattform Public and private Cloud Very easy

8 OpenNebula Architecture Monolithic Compared to other Software However subsystems are modular One Frontend VM-Hosts ( Nodes )

9 History Source:

10 OpenNebula Users

11 How to talk OpenNebula

12 OpenNebula Entities Users, Groups, ACLs Virtual Machines, Templates, Images Hosts, Datastores, Virtual Networks Clusters, Zones Marketplace

13 User, Groups, ACLs

14 Virtual Machines Based on Template Some parameters can be changed, but not all (!) Template Network Image (s) CPU/RAM Constraints

15 Infrastructure Hosts Datastores Shared/Local NFS/GlusterFS/Ceph/Sheepdog/ssh Virtual Networks Bridging VLAN VXLAN

16 Marketplace

17 Technology Overview What is the heart of OpenNebula?

18 Frontend Ruby On Rails Various (shell) Scripts Database sqlite MySQL...

19 Frontend / User Authentication Native (Database based) SSH x509 (Certificates) LDAP Active Directory

20 Hosts / Nodes Virtualisation KVM Xen VMWare Hyper-V Authentication / Authorization SSH oneadmin user

21 Storage Non-Shared SSH GlusterFS (*) Ceph Sheepdog (master branch/addon)

22 Networking Bridging Firewalling Openvswitch VXLAN

23 How to Setup

24 OS CentOS/RHEL and Ubuntu (recommended) Archlinux / Debian working Probably (!) runs on any Linux Requirements Ruby, libstdc++, Shell (Frontend) kvm + ssh (Node)

25 How to Setup Add OpenNebula Repository Install Software (apt-get, yum, ) Package for frontend (Ruby Gems for frontend) Package for nodes

26 OpenNebula Frontend Webfrontend ( sunstone ) Ruby On Rails Database: Sqlite / MySQL Optional: Webserver (f.i. nginx) for SSL Scheduler ( oned ) Monitoring Management

27 Frontend Requirements

28 OpenNebula Node oneadmin user No root access required after installation SSH keys of frontend oneadmin user Management Monitoring KVM / Xen / VMWare

29 Minimal Configuration Add (Datastore) Network Host Image Template

30 Experiences: Setup Installation mostly straight forward Documentation for advanced methods (Ceph, GlusterFS) can be improved VERY easy to extend Especially for storage / virtualisation ~4 scripts for Sheepdog support

31 How to use

32 How to use Sunstone (WebUI) https with f.i. nginx wss for VNC API (XMC-RPC) Command Line Interface

33 WebUI / Sunstone

34 Command Line Interface one* User: oneadmin Mostly: onevm & onetemplate [21:19:06] entrance:~$ one one onedatastore oneacct onedb oneacl oneflow onecluster oneflow-template oned onegroup onehost oneimage onemarket onetemplate oneuser onevcenter onevm onevnet onezone

35 Experiences: Using CLI is mostly consistent Error messages could be better Check /var/log/one/*.log (!) WebUI works rather smooth Some operations easier than in CLI

36 Demo

37 Advanced Topics

38 Clusters Mapping of Resources to groups Hosts Networks Datastores Templates Selecting clusters

39 Virtual Data Centers Mapping of groups to resources Can be used with clusters Or parts of clusters

40 Cloud Bursting / Hybrid Cloud Public Cloud treated as a host Azure Amazon Softlayer

41 High Availability: Frontend HA Cluster with Corosync / CCS / Ricci Anything that detects/ensure other node is down MySQL Multi Master for data redundancy

42 High Availability: Virtual Machines Host down detection (standard) Hooks STONITH Re-Deploy

43 Federation Combine Multiple OpenNebula Instances Users, Groups, Networks, VDC, ACLs, Zones MySQL Replication Zones

44 Hooks Virtual Machines Hosts Create, Running, Shutdown,... Create, Error, Disable Other Users, Groups, Networks,...

45 Conclusion?

46 Conclusion OpenNebula is easy to setup and maintain Simple, but flexible Solves real world problems Small, but active community
