Sorry, I don't see this as something we should support.
If you have a fix, I am cool with that, but its a very complicated bit
of code, I would rather make simpler not more complex, for just an edge
case.

Title:
Can't do "resize" on shared storage
Status in OpenStack Compute (Nova):
Won't Fix
Bug description:
Can't do "resize" to instance (at least to bigger flavor) on shared storage
using XenServer as hypervisor.
Additionaly, if fails to "resize", VM is crashed too, I don't get a way to
restore it in OpenStack. In XenServer VM is running, but by different name:
Before - instance-00000031
After - instance-00000031-orig
