Mount to a live system or use the install disk and use rescue mode. I'm assuming that you have something like a standard install on /dev/sda (boot in /dev/sda1 and data in /dev/sda2?) You can check this from the prompt by running cfdisk /dev/sda, to see how the disk is configured. Once you know how the disk is configured, use lvm tools to dig into it. lvmdiskscan will show you the volumes. lvscan will show you the status of the drives. lvdisplay will show you the LV and VG names. vgchange -ay will make the volumes active, and lvscan should then show you the appropriate volumes: /dev/qubes_dom0/root Then you should be able to mount /dev/qubes_dom0/root and back up the VM data from there. If you need more help or something doesnt look right, just ask. (Cloning the disk was a good move, and would have been my first bit of advice.) -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
