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"..

Thanks,
Kiall

I would like to move all instances into /home/storage/nova/instances.


The following value in nova.conf specifies where the images are located:

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!

Daniel
