[libvirt-users] 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 -- ----------------------------------------------------------------------------- Marc Haber | "I don't trust Computers.

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. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

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

Is there a bug/request tracker for libvirt? Greetings Marc -- ----------------------------------------------------------------------------- Marc Haber | "I don't trust Computers.

Why is it not practical, if virt-manager is patched to create such pools automatically on your behalf for traversing subdirectories?
