Hi
In my environment, I have 3 ovirt nodes as one cluster. And on top of host-=
1, there is one vm to host ovirt engine.
Also I have one external storage for the cluster to use as data domain of e=
ngine and data.
I confirmed live migration works well in my environment.
But it seems very buggy for VM failover if I try to force to shut down one =
ovirt node. Sometimes the VM in the node which is shutdown can migrate to o=
ther host, but it take more than several minutes.
Sometimes, it can not migrate at all. Sometimes, only when the host is back=
, the VM is beginning to move.
Is there some documentation to explain how VM failover is working? And is t=
here some bugs reported related with this?
Thanks in advance,
Cong
