For some reason, the first video wouldn't play here, so I can really
comment on the second one, but I don't think there was a screen
sharing here. It demoes Android running in a domU, which is already a
nice achievement, but it's not really the part that concern me the
most. I'm slightly more concerned about the two VM displaying stuff at
the same time.

Ideally, we would like both to be domU, with dom0 only taking care of
the composition.
