Hi, I'm trying to create a snapshot from a VM, but this fails with: "error: unsupported configuration: internal checkpoints require at least one disk to be selected for snapshot". This seems to be an error message from libvirt... I'm using OpenNebula 4.2, libvirt, KVM and Ceph (the VM has a RBD device). Any ideas what could be wrong here? Cheers, Tobias
