Public bug reported:
If you attempt to boot a nova instance without Neutron properly
configured for neutron/nova notifications, the instance will eventually
fail to spawn:

At this point, `nova list` will show:

And it appears to be impossible to delete this instance. Running "nova
reset-state <instance>" has no effect (with or without --active), nor
does correctly configuring neutron.
The only way to get rid of this instance appears to be directly editing
the database.
