So I'm assuming /dev exists, and is a directory?

Yeah, one thing about this which I forgot. guestfsd opens /dev/virtio-ports/org.libguestfs.channel.0, see http://git.annexia.org/?p=libguestfs.git;a=blob;f=daemon/guestfsd.c;h=eb1... This device won't exist unless (1) udev is running and populating /dev properly -- see above. And (2) the udev rules exist for virtio-serial. It might be that (2) requires an updated version of udev from a later Ubuntu release. In Ubuntu 11.04 the rules are in '/lib/udev/rules.d/50-udev-default.rules'.
