Many readers of this blog, as well as my work on the Open@Cisco Blog, will be familiar with both OpenStack and oVirt. I have written many posts on OpenStack and oVirt, but what I want to do with this post is compare the two. Examining where each project has it’s roots, as well as it’s current status and how the two Open Source projects may converge in the future, is a worthy exercise.

So, previously on the other site I blog for, I mentioned VXLAN in OpenStack Quantum. The reasons for this are dictated in that post. While we can start working on the segment ID and multicast address management in Quantum, getting VXLAN support into Open vSwitch can be done in parallel. That process has seen renewed interest recently (see the thread here), and I am happy to report I have setup a git repository with the patches from last fall merged into the latest master branch versions of Open vSwitch.
