16. What is oVirt?

17. Large scale, centralized
management for server and
desktop virtualization
Based on leading performance,
scalability and security
infrastructure technologies
Provide an open source alternative
to vCenter/vSphere
Focus on ease of use/deployment
Focus on KVM for best
integration/performance
What is oVirt?

18. 18
Kenrel-based Virtual Machine
● Included in Linux kernel since 2006
● Runs Linux, Windows and other
operating system guests
● Advanced features
– Live migration
– Memory page sharing
– Thin provisioning
– PCI Pass-through
● KVM architecture provides high
“feature-velocity” – leverages the
power of Linux

19. How Does It Look?

20. Basic User Portal

21. Power User Portal

22. Mobile client – Internet of things
● Instant access to information
● Mobile browsers don't fit
● Notifications
● Advance options to users

23. ArchitectureArchitecture

24. High level design

25. High level design

26. Class view

27. moVirt – Current abilities
● Agentless
● Lightweight
● Android Client
● Simple/Clean sources – simple to extend
or modify
● Instance monitoring
● Compatible with oVirt 3.4 and Android 4.x

28. MoVirt – Login

29. MoVirt – VM Information

30. MoVirt – Events

31. MoVirt – VM Operations

32. MoVirt – VM Events

33. What does moVirt allow to do?
● Allows to set “triggers” (memory, CPU,
state)
● Monitors VMs (all in cluster or just some)
● If trigger matches, fires notification
(vibrate, beep)
● Shows details and events
● Allows start/stop/reboot

34. MoVirt – Trigger Settings

35. MoVirt – VM Notifications

36. Future Plans
● Performance testing and tuning
– Push (Google Cloud Messaging for Android,
Aerogear) vs Poll
● Integrate SPICE (aSPICE)
● Integrate an SSH client to hosts
● User Interface:
– Visually nice DC overview
– moVirt Widget
– Advanced VM management (instance types,
imagetemplates management)

38. What's going on with moVirt
● History
– mpolednik have started in his free time implement an iOS clone of movirt
● Now days
– mbetak have taken movirt as a diploma thesis and started to implement a
server side for it making it possible to push the changes instead of polling
– Currently as a part of OPW a girl from India called Sphoorti is working on it
(the round will end soon, in ~1 week)
– We have proposed it for next round of OPW (or outreachy as it is named
now)
● Plans:
– We would like to integrate the hosts to moVirt making it a useful tool for
admins in server room. The use case we dream about is this:
● Have a simple script which will generate QR codes for all hosts in your
system (simple command line tool)
● You print them and put them on your physical boxes
● Than in server room you can just scan the code, it will open the hosts
screen, it will show you what VMs are running on it etc.
● Put the host to maintenance, do something physically with the host,
start again and than check if the hosts is up again.
