very nice!
in a related note, the VMWare tools package, which is supposed to 'enhance
performance' by installing 'specially tuned' drivers into a guest, doesn't
include net or HD drivers for linux! i was surprised, but it simply said
that using e1000 emulation on 64bit linux was optimised enough. since i saw
good performance (no hard benchmarks, but definitely not bad); i thought that
they do some paravirtualizification at runtime as part of their software
recompiling (because they're much older than HVM-capable processors).
now it seems that there are higher-level hardware that can be emulated far
more efficiently than the original set of QEMU hardware.
the next step would be to emulate LSI SCSI chips, eh?
