BTW, another problem about mount:

[malei at xen-test2 ~]$ guestfish --rw -a d.img -m /dev/vda1:/:utf8
libguestfs: error: mount_options: you must mount something on / first
guestfish: '/dev/vda1' could not be mounted.  Did you mean one of these?
/dev/vda1 (vfat)
/dev/vda2 (ntfs)
/dev/vda3 (ntfs)
/dev/vda4 (unknown)
/dev/vda5 (vfat)
/dev/vda6 (vfat)
/dev/vda7 (ntfs)
