Hey Daniel,
I think there is a flag you can put inside nova.conf but I don' recall it...

As it happens, they're in /var/lib/nova/instances. My server is set up such that /home is a 6TB LVM volume, whereas /var/lib lives on the relatively tiny root disk.

But how do I convince Nova that things have changed? Also, the various libvirt.xml files have references to /var/lib/nova/instances. Is it a manual process to change these references? Or is there some magical migration command that would fix everything for me? :)
