Description Richard W.M. Jones 2014-11-19 17:09:49 UTC

Description of problem:

The mount-loop command fails in guestfish.

Version-Release number of selected component (if applicable):

libguestfs-tools-c-1.29.8-1.fc22.x86_64
(On Fedora 21)

How reproducible:

100%

Steps to Reproduce:

Download the disk image here:
http://oirase.annexia.org/virt-p2v/livecd-p2v-201411180515.iso

guestfish -a livecd-p2v-201411180515.iso
><fs> run
><fs> mkmountpoint /1
><fs> mount /dev/sda /1
><fs> mkmountpoint /2
><fs> mount-loop /1/LiveOS/squashfs.img /2

Actual results:

mount-loop command fails with an error like:

libguestfs: error: mount_loop: /1/LiveOS/squashfs.img on /2: mount: /sysroot/2: mount failed: Unknown error -1

Note that I can download the squashfs and then open
it with guestfish, so it doesn't seem to be a problem
with the file.

Seems to be a variation of bug 1159430.

Comment 2 Richard W.M. Jones 2014-11-20 13:10:14 UTC

We needed to pass the --boot parameter.  Patch posted:
