> KVM - HA - one of the Vms failed to start on another host when the host that it was running
on was shutdown.
> Set up:
> Advanced zone with 2 KVM hosts (RHEL 6.3).
> Had 5 user Vms running on each host.
> Shutdown host1 ( execute  echo o > /proc/sysrq-trigger on host)
> All VMs from host1 , get HA-ed to host2.
> Bring host1 up.
> Shutdown host2. (  execute  echo o > /proc/sysrq-trigger on host)
> All VMs from host2 get HA-ed to host2 , except for 1 user Vm.
> It encounters the following exception in the agent logs when management server tries
to start this Vm as part of HA process.
