Re: Changing the location of Nova's instances


Personally, I would make use of a bind mount[1] 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.

Of course, I would shut down all instances and copy everything to the new location. But how do I convince Nova >that things have changed?

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!
