Hi Ron, Thanks for your reply. Problem solved. It was my brain mixing /dev/d/ and /dev/mapper. Releasing the partition device with kpartx -d worked - as long as I use the correct path and not mix the VG name with "mapper". Duh... Radu: the first test I'll do is not to zero the partition but to restore the image now the partition device (/dev/d/xm.wxp1) is gone. I don't understand why it's there in the first place (dom0 has no business there). If that helps, the presence of that partition device apparently interferes with the VM. If that doesn't help, I'll zero the blocks and report back (some time next week). thanks folks for the help, Jan _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
