I've been doing a lot of instance creation/deletion/evacuate and I've

then the instance rootfs stays around in /var/lib/nova/instances/.
Eventually this could add up to significant amounts of space.
Is this expected behaviour? (This is on grizzly, so maybe havana is
different.) If not, should I file a bug for it?
I think it would make sense for the compute node to come up, query all
the instances in /var/lib/nova/instances/, and delete the ones for
instances that aren't in the database.
How long are you waiting after starting up the compute node? I would
expect it to get cleaned up by a periodic task, so you might have to
wait roughly 10 minutes (by default).
This is nearly 50 minutes after booting up the compute node:

Of these, only two show up in "nova list".
