udevd is definitely there (I see 1 instance, not three). udevd complains
about /dev/null being missing, and /dev is pretty empty (there is only a
kmsg file there).
So I'm assuming /dev exists, and is a directory?
The other big problem I see right now is that virtio-serial isn't
working
properly (which is the ultimate message I see). I'm trying to debug that a
bit by manually starting a simple KVM with the virtio-console flags and
seeing if that works.
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'.
