Hi,
with my laptop I actually had better experience with recent qemu, but I
gave up on xen back then and went to kvm instead.
Then got stuck on that I need PS/2 passthrough, hacked it in, discussed
it with kraxel and he rather rewritten it himself. my hacks in qemu were
too awful xD
But yeah, it needs a lot of debugging and experimenting and it is not
that easy when you cut off yourself off the machine with only gpu :)
I have radeon gpu in the laptop though, no idea on intel ones, there
were even some patches for that that might not be in the qemu and will
need to recompile for that? not sure :(
