What is oVirt?

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

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

How Does It Look?

Basic User Portal

Power User Portal

Mobile client – Internet of things

● Instant access to information● Mobile browsers don't fit● Notifications

● Advance options to users

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

MoVirt – Login

MoVirt – VM Information

MoVirt – Events

MoVirt – VM Operations

MoVirt – VM Events

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

MoVirt – Trigger Settings

MoVirt – VM Notifications

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,

image\templates management)

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.
