[libvirt-users] Creating a snapshot from a KVM VM fails
Hi,
I'm trying to create a snapshot from a KVM VM:
# virsh snapshot-create one-5
error: unsupported configuration: internal checkpoints require at least
one disk to be selected for snapshot
How can I debug this error message and what does it mean?
Some system information:
* Ubuntu 13.04 64Bit
* virsh --version: 1.0.2
* The XML of the VM is below
Thanks for all help...
Cheers,
Tobias
