Re: understanding ephemeral and persistant volumes
This is how it happens in trunk now, but I cannot remember how it was in Diablo.
I had left-over directories when the instances were not properly terminated, but otherwise they clean up nice.

So by default the disk of an instance is basically stored on the local filesystem of the server where the instance is running (in "/var/lib/nova/instances/instance-0000000X/disk"), and it's called ephemeral because when you terminate the instance the entire directory "/var/lib/nova/instances/instance-0000000X" gets deleted and the virtual disk is gone, but the base image in the "_base" directory is not touched.
Does this actually happen in diablo? I have a lot of /var/lib/nova/instances/instance-0000000X directories on my system even though the associated instances were terminated a long time ago.
Take care,
