This is a generic timer problem linked to the fact that a 2.6.x guest 
kernel is used. This problem especially arises if you are using a 2.4.x 
host kernel.

A workaround is to add "clock=pit" on the guest kernel command line 
(type 'linux clock=pit' as boot argument in the Fedora installer).

If you use a 2.4.x kernel, make sure you also did
'echo 1024 > /proc/sys/dev/rtc/max-user-freq' as root.
