qemu now accepts kernel help in executing its vm. http://fabrice.bellard.free.fr/qemu/qemu-accel.html
the interesting parts of the kernel module itself are closed, but the interface that qemu uses is open. if anyone out there feels like x86 hacking, it would be cool to have a plan 9 version of the module so that qemu could be used as a vmware-substitute that ran on top of plan 9. russ
