Looks like the same issue as mine. But any way - a full log of guestmount, running it with -v -x and host + VM info are attached, probably I've missed something important in the output.
Indeed, the log shows that as well: mount -o ro /dev/sda2 /sysroot/ [ 2.673870] SGI XFS with ACLs, security attributes, large block/inode numbers, no debug enabled [ 2.674968] SGI XFS Quota Management subsystem [ 2.675522] XFS (sda2): bad version [ 2.675754] XFS (sda2): SB validate failed mount: wrong fs type, bad option, bad superblock on /dev/sda2, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so guestfsd: error: /dev/sda2 on / (options: 'ro'): mount: wrong fs type, bad option, bad superblock on /dev/sda2, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so guestfsd: main_loop: proc 73 (mount_ro) took 0.07 seconds so you need a RHEL/CentOS 7 (or another distro with a kernel >= 3.16) to mount that XFS filesystem. -- Pino Toscano
