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

Hello Richard and all, (continuing from https://www.redhat.com/archives/libguestfs/2014-September/msg00112.html ). I'm experimenting with libguestfs on non-linux VMs, encountered errors on FreeBSD9.3 and MINIX3 (and few others, but these ones are easy to share), with host Ubuntu 14.04.01 LTS x86-64. Attached are logs from "virt-inspector -v -x" for each VM. The images are here: http://files.housegordon.org/libguestfs/minixR330.qcow2.clean_install.xz (44MB) http://files.housegordon.org/libguestfs/freebsd93.qcow2.clean_install.xz (161MB) To run them: xz -dc < minix3/minixR330.qcow2.clean_install.xz > minixR330.qcow2 kvm -drive file=minixR330.qcow2,if=virtio,media=disk,index=0 \ -m 384 -curses -net user -net nic,model=virtio xz -dc < freebsd93.qcow2.clean_install.xz > freebsd93.qcow2 kvm -drive file=freebsd93.qcow2,if=virtio,media=disk,index=0 \ -m 384 -curses -net user -net nic,model=virtio Root password for freebsd is "12345". Root in Minix does not require a password. Regards, - Assaf ==== Disk structure from within MINIX3 VM guest ==== # fdisk /dev/c0d0 Geometry of /dev/c0d0: 10402x16x63 Inconsistent size in partition 1. Suspect head and sector parameters. Disk appears to have mis-specified number of heads or sectors.
