I've encountered this problem using EC2 EBS volumes.
(the 'ghost image' (AMI) contains btrfs filesystems. This results in all
child VMs having EBS volumes sharing the same UUID ... and it's then not
being possible to move volumes around.)
I'm interested to know if there's a possible solution, aside hoping you
can run mkfs.btrfs on first boot...
