Sure, basically a way around this is to do migration of the VM's on the
host u are doing maintenance on.
That¹s one way y! has its ops folks work around this.
Another solution is just don't do local_deletes :-P
It sounds like your 'zombie' state would be useful as a way to solve this
also.

+1 to what Chris suggested. Zombie state that doesn't affect quota, but
doesn't create more problems by trying to reuse resources that aren't
available. That way we can tell the customer that things are deleted, but
we don't need to break our cloud by screwing up future schedule requests.

This brings up another question, do people actually like/use the
'local_delete' feature in nova?
In general it seems to free resources that are not actually capable of
being freed and has been problematic for y! usage.
Deleting from the DB allows another request to actually take those
resources

A scenario that I've seen:
Take 'nova-compute' down for software upgrade, API still accessible since
you want to provide API uptime (aka not taking the whole cluster offline).
User Y deletes VM on that hypervisor where nova-compute is currently down,
DB locally deletes, at this point VM 'A' is
