I think I actually need this. One large VM (~30GB) doesn't boot (can't start terminal or anything), but before I delete it, I want to backup some stuff, so it would be great if I could mount that volume from dom0 manually, right?
$ sudo mount /dev/qubes_dom0/vm-crowphale-private-snap crow-mount mount: wrong fs type, bad option, bad superblock on /dev/mapper/qubes_dom0-vm--crowphale--private--snap, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so.
Any pointers how to do this?
