Ok I see what went wrong. 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. Jan Jezabek wrote:

Question 2) Qemu runs and XP as guest is working on a Linux FC7 host.I installed kqemu from sources (kqemu-1.3.0pre11.tar.gz) and it configured/mak/make install without errors.However, when I e.g. start a VM, I still get the following error: qemu]# qemu -hda WinXP_Home.img Could not open '/dev/kqemu' - QEMU acceleration layer not activatedSo it seems that devices were never created. there is also no kqemu daemon or anything I can verify kqemu to be running.It is not in processes either.Maybe I misuunderstand how kqemu works, but usually it should be a daemon if it creates a device '/dev/kqemu' at installation !Any Ideas where I got the cat by the tail?KQEMU is a kernel module. You'll need to do /sbin/modprobe kqemu(as root) before you start QEMU. Then the warning will go away and QEMU will be accelerated.Regards, Jan Jezabek
