You could try a couple of things: (1) Use: virt-filesystems -a /vm/images/archlinux/archlinux.qcow2 --all --long -h to list out the filesystems in the image, then try mounting them manually, as in this example, note the -m options which you will need to adjust according to the output of virt-filesystems: guestmount -a /vm/images/archlinux/archlinux.qcow2 \ -m /dev/vg/lv:/ -m /dev/sda1:/boot \ /mnt (The error message indicates you are lacking Augeas, which we use to examine the disk image for the right mountpoints, so you'd have to do that by hand.) (2) Set the following envionment variables and run the original guestmount command again: export LIBGUESTFS_DEBUG=1 export LIBGUESTFS_TRACE=1 Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones libguestfs lets you edit virtual machines.
