I accidentally had a XEN kernel still running so insmod did not work. Now it works and the message disappeared. But, kqemu is not much faster than qemu. I perceive about 1.5x over a 1gbit network to a terminal through an x session. It is much much slower than win4lin, but it is free and I can live with it under most applications except streaming. Is there something I could have done wrong? Server: Dual Opteron 1.6Ghz/16G SUN V20Z Terminal: Mac Mini 1.6GHz Connected with 1Gbit network.
