is an endpoint registered for the glance service?

Ah, that appears to do it. I wasn't previously aware that there were
volume management commands in both 'nova' and 'nova-manage

prefer to be able to delete things regardless of their state using
established tools, rather than manipulating the database directly.
I'm always worried that I'll screw something up due to my incomplete

I have confirmed that the DNAT rule works *unless* metadata_host is

That's good to know. We try as much as possible to avoid solutions
that involve poking at the database, but we can probably live with
this. Especially since MySQL knows about IP addresses (so we can
