I seem to be having trouble using guestmount to mount a Fedora 24 disk that is
using XFS. This is the error messings I get when I try:
root@cpdev-cn5:/var/lib/libvirt/images/base# guestmount --rw -a
${disk_path}/${disk_name} -m /dev/${target}1 /tmp/fedora-master/

dmesg | tail or so
guestmount: '/dev/sda1' could not be mounted. Did you mean one of
these?
/dev/sda1 (xfs)

I've tried with both /dev/sda1 and /dev/vda1 but no luck. Interestingly
enough, a CentOS 7.2 image with XFS and the same setup (i.e., a single partition
formatted with XFS) mounts without issue. Any ideas?

Re: [libvirt-users] Cannot guestmount a Fedora 24 XFS disk.
The host is running Ubuntu 12.04 LTS and has the libguestfs package installed -- which, if I'm not mistaken, provides libguestfs-xfs: https://launchpad.net/ubuntu/+source/libguestfs Andre Goree ________________________________________ From: Richard W.M.
