[one-users] High avaliability

[Ara Sadoyan]

Thanks Daniel.

Have you tried this? 
I have dual master DRBS/OCFS2 and all I need is just to restart VM from failed host on live one.
Something very similar to live-migrate as VM disc is located on DRBD volume and is accessible from both hosts.
The only bad think in my scenario is that HOST_HOOK is deleting VM disc from DRBD volume and creating new one from image.
Do you know away to run VM on second host without recreating it from image.

Thanks in advance
Ara
