Can anyone shed some > light on this? Your problem is nothing to do with libguestfs, but anyway. libguestfs depends on a working qemu, which is broken in Ubuntu 12.04. See this thread: https://www.redhat.com/archives/libguestfs/2012-April/thread.html#00028 and this bug comment: https://bugs.launchpad.net/ubuntu/+source/seabios/+bug/931371/comments/12 We don't have anyone maintaining libguestfs in Ubuntu, so what you are getting is just random packages pulled out of Debian. Not surprisingly that often doesn't work. I do my best to help out, but it's not my primary development platform, and I don't have permissions to commit the required fixes to qemu/seabios in Ubuntu.
