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?

I think there are two parts to achieving this:
1. Have a script that migrates VMs off a specific host. This should be easy
to write using the Python/Ruby/Java SDK, Ansible or using REST directly.
2. Having this script run as a service when a host shuts down, in the right
order - well before libvirt and VDSM shut down, and would be fast enough
not to be terminated by systemd.
This is a bit more challenging.
Who's shutting down the hypervisor? (Or perhaps it is shutdown externally,
due to overheating or otherwise?)
Y.

Hi,

, due to overheating or otherwise?)
We need a continuous availability of VM's in our production setup. If the h=
ypervisor goes down due to any hardware failure or work load then VM's abov=
e hypervisor will reboot and started on available hypervisors. This is norm=
ally happening but it disrupting VM's. Can you suggest a solution in this c=
ase? Can we achieve this challenge using glusterfs?

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.
