[ovirt-users] HA without Power Management

[Oved Ourfali]

Hi Sebastian

Currently in case a host is not responding, the only way to make sure no
vms are running on it is to fence it, and we only support fencing through
power management.

In 4.1 we plan to have limited options for storage fencing. This will mean
that if a host is not responding then we try to run HA VMs on another host.
If the host is still up then it will fail, as the non responsive host is
the one holding the lock. If, however, the host is really dead, then the
run VM should succeed.

So, a VM should be up and running, but it might run on a host that has
connectivity issues.

Better than what you have now, but still partial. I guess this might get
improved during 4.2.

Regards,
Oved
