Ah, not xfs, but you helped me. Now I understand what the message means :-) $ virt-sysprep -a ... [ 0.0] Examining the guest ... virt-sysprep: error: libguestfs error: inspect_os: mount exited with status 32: mount: /tmp/btrfse5L6v2: unknown filesystem type 'btrfs'. This is the absence of 'btrfs' on EL8. So there's no way out from this on any currently supported RHEL, I bet.
