Description

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.
