Title:
Live migrate abort results in instance going into an error state
Status in OpenStack Compute (nova):
Expired
Bug description:
Only the libvirt driver supports live migration abort (and that may
have some caveates if the action results in a exception). If the call
takes places with a driver that does not support the opertaion then
the follow stack trace appears:
nova live-migration-abort doesn’t work.
It failed with exception "NotImplementedError".
Steps:
1) Do live migration (make sure vmkernel adaptors has vmotion enabled)
2) During live-migration is going on from one cluster to another trigger
command nova live-migration-abort.
3) you will see nova instance goes into ERROR state.
