There's also Gerd's domU kexec work.

I'd really like to see domU PV PXE boot support to complement the HVM
support. The easiest way might just be to hack something together in
dom0, though. 'tftpc' can be used to fetch the kernels. The easiest dhcp
client to use is probably udhcp. I'd probably hack it to take a MAC
address on the command line, and then exit after getting a response (or
timing out). We should be able to run udhcp against the guests's vif, or
possibly the bridge its connected to.

It would be excellent if someone could work on this and try and get a
patch into 3.0.5.

Thanks,
Ian
