Great.

Strangely those were vbd (aka disk) errors.

xenbus_probe_frontend is a module. It should either be built in or
Ubuntu's tools (primarily the one which builds initrds, but perhaps also
something in  the live-cd suite) need to learn to load it manually at
the appropriate times. It's a tiny module so we would generally
recommend building it in.

You should file this as a bug against Ubuntu, I think. I'd have sworn
this had been reported to them before but perhaps it has regressed.
