[Libguestfs] Issue with virt-sysprep

Hi, I'm trying to run virt-sysprep against a disk in Ceph RBD storage but I appear to be unable to do so. The commands (bold) and outputs I've had are: On Ceph node: *virt-sysprep -a rbd://localhost/libvirt-pool/ubuntu-12-04-beanstalk001* libguestfs: new guestfs handle 0x113b060 rbd://localhost/libvirt-pool/ubuntu-12-04-beanstalk001: No such file or directory libguestfs: trace: close libguestfs: closing guestfs handle 0x113b060 (state 0) On libvirt node: *virt-sysprep -d beanstalk002 --hostname beanstalk002 --format rbd* Examining the guest ... Fatal error: exception Guestfs.Error("libvirt domain has no disks") I'm using Ubuntu 13.04 on libvirt node and Ubuntu 12.04.3 LTS on the Ceph node. The libguestfs version showing in dpkg is 1:1.14.8-1. This works fine on qcow2 images that are on disk but I'm moving towards having all disks in Ceph RBD and would like to be able to virt-sysprep disks in there if at all possible. Please can you advise where I'm going wrong? -- Best regards *Graeme*
