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/ libguestfs: error: mount_options: /dev/vda1 on /: mount: wrong fs type, bad option, bad superblock on /dev/vda1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so guestmount: '/dev/sda1' could not be mounted. Did you mean one of these? /dev/sda1 (xfs) Verbose output shows: libguestfs: recv_from_daemon: received GUESTFS_LAUNCH_FLAG libguestfs: [03647ms] appliance is up libguestfs: send_to_daemon: 72 bytes: 00 00 00 44 | 20 00 f5 f5 | 00 00 00 04 | 00 00 00 4a | 00 00 00 00 | ... guestfsd: main_loop: new request, len 0x44 /dev/sda1: No such file or directory mount -o /dev/vda1 /sysroot/ [ 1.759120] SGI XFS with ACLs, security attributes, realtime, large block/inode numbers, no debug enabled [ 1.762869] XFS (vda1): Version 5 superblock detected.

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?
