Got this to compile using 2.6.15-rc5 (host/guest). I had to manually
apply two small patches in the guest.

I had to use the attached patch for the vmm.

The problem is that it does not boot, I get this:

$ vmm bootloader vmlinux maxcpus=2 simscsi=sd
args: vmlinux maxcpus=2 simscsi=sd
Allowing running on processor 0 of 2
pagesize = 16384
Physical memory at 0x80000 -> 0x20000000

Any clue?
