Not exactly. We are aiming for the basic functionality for running a PV guest
in that timeframe. Right now, you probably can run an HVM guests, thought we
have been so focused on shaking out bringup bugs that it has not been on our
list of high priorities.

However, something which I did not know until last week, is that there is a
blkback and netback built in QEMU. Which means you could boot up a PV guest
with the blkback/netback utilizing the QEMU back-ends - how well they do, I don't
know. I am not even sure how to utilize it - it might be worth digging in that
and finding out how well it works?
