Thanks for the update, it sounds like it's pretty far along.
The PV enhancements etc sound great but it would be nice if we could tie
up the baseline stuff so that folks can start using it.
Is Bei still working on the project since the end of GSoC? If not is
there an archive of what he accomplished so that we can find someone to
pick up on it if necessary?

I remember these. A bunch got applied after some discussion but IIRC not
all of them were? Bei, are you able to resend the ones which did not?
Is there a wiki page or something somewhere detailing what a user needs
to do (i.e. build steps, guest cfg etc) in order to use the UEFI
support?
Cheers,
Ian.
