Hello,
We are now using oVirt 4.1 in our lab with 2 hosts and a separate server
for engine. Both hosts (Dell R710 Servers) are in a single cluster and
load balancing & migrations work perfectly.
However, if a physical server goes down, the VMs running on that server,
gets paused ans status goes changes to "?". They do not move or restart
on the another host automatically. We have to manually intervene, stop
the VMs, restart them on another server.
Is there a way in which this migration can be automated?

Thanks & Regards,
Anantha Raghava

Have you marked the Virtual Machine as “highly available?” Under the “highly availability
tab” under Advanced Options while editing the VM?

Hello,
Did you configure power management?
HA works only if power management is configured and vms are set as highly
available.

If you don't have power management, you should check VM lease:

In order for oVirt to migrate VM's it needs to ensure that the VMs are
no longer running on the failed host. Essentially it need to ensure
that host is no longer running (As opposed to not accessible over the
network). You need to configure power management for it to be able to
do that.
(There is a new feature in 4.x to enable storage-based fencing, can't
find a reference for it just now).
