Hi there,
You probably heard about XenServer 7.3 release and some of its features removed.
So, I started a GitHub organization called "xcp-ng", hosting all the repo needed to make a XenServer OS from the sources. It's 100% community backed.
I actually hired (part time but still) an former XAPI developer, so it will accelerate the pace soon. I think we'll be able to release something in Q1, without any feature restriction (think vGPU + everything) and turnkey as XenServer itself.
If it works well, the door for including directly extra stuff in the project is opened: our Gluster driver for example (and a Ceph driver too), better compression algorithm, CentOS packages available, community contribution etc.
Obviously, we'll start small (probably re-using bunch of existing RPMs), but then we'll try to build more and more from the sources. But the ultimate goal is to have just a RPM repo to install from a CentOS and then use yum upgrade
to stay up-to-date!
All contributions are welcome, if you want to join the GitHub org, feel free to ask!
