just to clear this one up - there is no reason ceph won't get support - 
just need someone to write some patches to do so.

we made great progress to enable other platforms to work (new 
development environment, vdsm work for ubuntu, guest agent work for 
ubuntu, guests os's now configuration driven, etc).
we'd welcome and help anyone trying to help with making oVirt more 
robust on other platforms.

while few is subjective, i took a look at the stats from 1/1/2013. oVirt

authors. vdsm is next with > 400 commits from 47 distinct authors for 
vdsm (some overlap between authors exist).

we started this with http://www.youtube.com/ovirtproject, and would 
welcome any help (since they could be considered promotional, the 
matching RHEV ones like [1] were not added there)

Glad to see you like it, please don't hesitate to provide additional 
feedback, and we welcome any help, doesn't have to be with code - web 
site help is appreciated as well (it is all a wiki).

Again - thank for this email - I really appreciate it.

Thanks,
