edison su resolved CLOUDSTACK-5574.
-----------------------------------

    Resolution: Won't Fix

KVM itself reports error that can't start the vm, seems nothing we can do for it. Maybe we can reproduce it and grab more kvm logs, to future identify the issue.

> 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.
