             Summary: VMSnapshot on XenServer: RevertToVMSnapshot failed to revert VM to Snapshot
                 Key: CLOUDSTACK-3677
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-3677
             Project: CloudStack
          Issue Type: Bug

            Reporter: Chandan Purushothama
            Priority: Critical
             Fix For: 4.2.0


Setup: Advanced Zone, XenServer 6.2

=================
Steps to Reproduce:
=================

1. Deploy Vm.  Attach muiltiple data disks to this VM.
2. Log in to the Vm and create few directories and files on the root volume. Create few more
directories on each of  the data disks.
3. Stop the VM. Create VMSnapshot for this VM with "vm_snapshot_type" set to "Disk".
4. Revert to the VMSnapshot and observe the failure
