You do know you can configure the instance name used...

instance_name_template='inst-%(uuid)s'
Please note that you CANNOT change instance_name_template ones instances
are created otherwise they become unmanageable by Nova. This is because
Nova tries to find the libvirt instance by its name instead of its UUID.
So since instances were spawned with the old value, it won't find
existing instances using the new value.
And no, I haven't found a way to rename an instance without
redefining/restarting it in libvirt.
Is there any reason why we couldn't default to using something like
'inst-%(uuid)s' for the instance name?
I guess it's for the reason I mentioned above:
To not break all OpenStack installations on Earth running with default
config values.
So that's not breaking *upgrades* of all OpenStack installations with default
config values, which is a slightly different thing.
