Original description
I'm working on the nova-powervm driver for Mitaka and trying to add
support for evacuation.
The problem I'm hitting is that instance.host is not updated when the
compute driver is called to spawn the instance on the destination host.
It is still set to the source host. It's not until after the spawn
completes that the compute manager updates instance.host to reflect the
destination host.
The nova-powervm driver uses instance events callback mechanism during
plug VIF to determine when Neutron has finished provisioning the
network. The instance events code sends the event to instance.host and
hence is sending the event to the source host (which is down). This
causes the spawn to fail and also causes weirdness when the source host
gets the events when it's powered back up.
To temporarily work around the problem, I hacked in setting
instance.host = CONF.host; instance.save() in the compute driver but
that's not a good solution.
