Two more related issues: -1- 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% minixR330.qcow2:/dev/sda6 1215924 -94776 1310700 -7% minixR330.qcow2:/dev/sda7 1895536 312296 1583240 17% =====

-2- 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: ===== [ 17.052574] You didn't specify the type of your ufs filesystem [ 17.052574] [ 17.052574] mount -t ufs -o ufstype=sun|sunx86|44bsd|ufs2|5xbsd|old|hp|nextstep|nextstep-cd|openstep ...
