Re: [Qemu-devel] Fedora Core 2 very slow

[Fabrice Bellard <fabrice@bellard.org>]

Sorry for this dumb question, but are you using a 2.6 host kernel or did 
you do the 'echo 1024 > /proc/sys/dev/rtc/max-user-freq' which is 
written when you launch QEMU ? Otherwise, you have no change of using a 
2.6 based guest OS...
