    Ok, this is coming back clean.  Do you guys agree I should merge this into 4.9 as it fixes
issues?  Thanks...

> {quote}
> Live migration was working in Cloudstack 4.5.1, the previous release that we upgraded
from.
> Steps to reproduce:
> # Create VM using local storage (no data disks are required to reproduce)
> # Attempt to migrate VM to another hypervisor in a XenServer pool
> # Migration will immediately fail with "Failed to migrated vm VM[User|i-X-XXXX-VM] along
with its volumes." and upon checking the management-server log, you will see a NPE like the
one above.
