[Libguestfs] RHEL 7 and guestmount of XFS volumes

Hi, I'm experiencing a weird behavior when tried to use guestmount with a XFS formatted volume. I have created a RHEL 8 virtual machine using libvirt. I have retrieved the disk image on a RHEL 7.7 server to mount the image root filesystem and explore it. The command returns an error message: # guestmount -a /disks/jamesdream.qcow2 -m /dev/sda1 /mnt/ libguestfs: error: mount_options: mount exited with status 32: mount: wrong fs type, bad option, bad superblock on /dev/sda1, 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. guestmount: Did you mean to mount one of these filesystems? guestmount: /dev/sda1 (xfs) guestmount: /dev/rhel/root (xfs) guestmount: /dev/rhel/swap (swap) I have also run the same command with -x and -v options and the log is attached. Seeing that it's not working on RHEL 7, I've tried the same command on another RHEL 8.1 machine and it works. Looking at libguestfs-tools package version, it appears that the package on RHEL 7.7 (1.40.2-5.el7_7.2) is more recent than on RHEL 8.1 (1.38.4-14.module+el8.1.0+4066+0f1aadab). Is that normal ?
