libvirt users - Sep 2014 - Re: How to have a directory and its subdirectories as a storage pool

Hi,

I would like to use btrfs subvolumes as storage place for VM images to
use snapshots.

Unfortunately, this does not seem to work in virt-manager at least
since the "filesystem directory" storage pool type does not allow me
to descend into subdirectories.

Is there a trick to do this? Can I do it with virsh, or in the XML?

Greetings
Marc

At the moment, you have to create a new storage pool for each
subdirectory you want to recurse into.  Yes, it would be nice if
virt-manager could automate this a bit more.

Which would mean one storage "pool" per VM, which is not really
practical.

Is there a bug/request tracker for libvirt?
