Now, before I go into any more hassle, has somebody else of you
done a live-backup solution for oVirt? Are there any
recommendations? Thanks for any help provided!<br>

I've been looking for a similar scheme for the last year. It was
not (really) possible in the past as there wasn't any way to destroy
a snapshot w/o shutting down the VM. Is this still the case, or
are snap shots fully implemented now?<br>
<br>
Basically, I'd like to:<br>
Tell VM to flush it's buffers<br>
suspend VM<br>
take snap shot of boot virtual disk<br>
resume VM<br>
backup the virtual boot disk from the Hypervisor using standard
commands (tar, cp, whatever)<br>
destroy the snapshot<br>
<br>
This would at least give some BMR capabilities of your VMs.<br>
<br>
Ideally, I'd also like to be able to create a snapshot from within
the VM, do a yum update, see if I like it or not, if I do, then
destroy the snap shot. If I don't, I want to promote the snapshot
and boot from that, then destroy the "original".<br>
(Yes, I know, BTRFS is supposed to be the solution to this with in
the VM at some point, isn't it?)<br>
<br>
I have looked at the oVirt backup API wiki, but the code examples
look more like pseudo code than real world examples.<br>
