Hi,
Anyone can suggest how to setup VM Live migration (without restart vm)
while Hypervisor goes down in ovirt?
Using glusterfs is it possible? Then how?
Can't speak for glusterfs specifically, but this is how things work.
All nodes know about the storage domains... this is so a different node
can "take over" in a live migration. Not necessarily designed for a
node to go down hard (but let's say the node has problems communicating,
it might get fenced and live migration begins, and of course, the usual
maintenance mode would force a live migration).... for hard down
scenarios you might want to look a HA for the VMs.
