Re: [Libguestfs] libguestfs fails on FreeBSD9.3, MINIX3 qcow2 images

Note that you can do useful things with libguestfs without

needing inspection to work. Libguestfs will open any disk image, but
without inspection you won't be able to detect OSes in the disk image
nor map devices to mountpoints, unless you do it yourself.

With minix, "virt-df" returns negative values:
=====
$ virt-df -a ./minixR330.qcow2
Filesystem 1K-blocks Used Available Use%
minixR330.qcow2:/dev/sda5 2075188 11892 2063296 1%

With the FreeBSD, "guestfish" can't mount the "ufs" filesystem:
=====
$ guestfish -a ./freebsd93.qcow2
<fs> run
<fs> list-filesystems
/dev/sda1: unknown
/dev/sda2: ufs
/dev/sda3: unknown
<fs> mount-ro /dev/sda2 /
libguestfs: error: mount_ro:
/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
=====
The "dmesg" (from without guestfish) shows this:
=====
