Public bug reported:
For example, take this scenario:
1. Assume an environment with a single host… call it host-1
2. Deploy a VM, but force an exception in the spawn path somewhere to simulate
some "hypervisor error”
3. The scheduler correctly attempts to reschedule the VM, and ultimately ends
up (correctly) with a NoValidHost error because there was only 1 host
4. However, the instance.host (e.g., [nova show <vm>]) is still showing ‘host-1’
After discussion on the mailing list and IRC, we decided this should be
considered a bug since the instance is no longer tied to the host since
it blew up in spawn and tried to reschedule. As such, we should clear
it out when the claim is aborted.
