It's a bug in nova (LP #1054212).

Depending on how it gets fixed in nova, it may have to be fixed in juju,
e.g. if it's fixed in nova by causing the instance spawn to fail.

If it's fixed in nova by silently changing the instance name, juju's
idea of the instance name and nova's will be out of sync.

It's not a pressing issue, for sure, but (personally) I think it makes
sense to fix this in juju as well as nova.
