[Openstack] Changing the location of Nova's instances
Personally, I would make use of a bind mount rather than trying to relocate..
A bind mount is just like a symlink, with the exception of AppArmor (and I presume SELinux) will handle it "correctly"..

Ah, ok! That's the info I was looking for. So the entire /var/lib/nova directory needs to be relocated, not just /var/lib/nova/instances. Got it.

I don't think there is a tool for that but a bash one-liner should be able to search and replace this in the XML files :)
This is true. And it's exactly what I'll do. :) Thanks for your help!
