> KVM - Primary store down - Hosts attempt to reboot becasue of primary store being down hangs.
> Set up:
> Advanced zone with KVM (RHEL 6.3) hosts.
> Steps to reproduce the problem:
> 1. Deploy few Vms in each of the hosts with 10 GB ROOT volume size , so we start with 10 Vms.
> 2. Create snaposhot for ROOT volumes.
> 3. When snapshot is still in progress , Make the primary storage unavailable for 10 mts.
> This results in the KVM hosts to reboot.
> But reboot of KVM host is not successful.
> It is stuck at trying to unmount nfs mount points.
