Hi i was testing HA of ovirt,(i am from Xenserver background and trying to
use KVM solution in our environment)
Have 2 hosts with NFS storage and i tested migration between these two
hosts.
On Host2 while VM was running on it, i unplugged Power cable and it took
long minutes to update that VM is down,okkk now long wait......
..
.....
.......
VM state changed to *unkown *and not booted on second Node ie Host1
its been half an hour and still the VM is not restarted
What can be the issue?What should i do it make the VM in real HA so that it
will be restarted on the active node.
*How HA is enabled*
what i did was while creating vm> Advanced option>High Availability>Highly
Available
I am sure this can be a configuration error,Can some one please help me
with enabling HA.
Please Help
Thanks

We don't restart the VM in that case on purpose, since we really don't know
what's the status of the VM - the host might have been just disconnected from
the network while the VM is still running (and connected to the storage),
so if we'll also run the VM on a different host, we'll get
"split-brain".
In order to restart HA VMs which were running on host that went down, you either
needs to have power-management defined for that host (for automatic restart) or
to trigger it manually by selecting "confirm host has been rebooted" when the
host is changed to non-responsive state (and you need to have additional host
which is up of course).

Thanks Arik,
I think that's the issue,i havent configured any
power management but could you tell me what to specify in power management
i see Address,Username,Password,SSH port and Type.
Using HP server with ILO2 so i filled Type as ILO2 but its confusing what
these
* Address,Username,Password *are
are these ILO credentials or My hypervisor credentials
Thanks

I tried that and now the "!" is gone and from control panel
restarted that server and it rebooted but the reboot happened only in
Ovirt control panel and actual server hasn't rebooted nor got shutdown its
up time still hasn't changed.
Any idea whats wrong
Thanks
