Included in the test image was an old byte bench mark utility, and though I don't think I installed the kqemu accelerator properly, qemu on the via was about twice as fast as qemu on my mac. (Both systems are dual processor, and both had a little bit of other software eating some cpu).
Also though slow, the qemu utilities provide something similar to vmware's server products. Qemudo looks promising. (Though vmware on the mak was about 5 to 10 times as fast as the non accelerated qemu on the via.
