Hi,
I'm running CentOS 5.5 (on ThinkPad x61). I use KVM to run a SLES 11.0 (32bits, kernel 2.6.27.19-5-pae) guest. The "cat /proc/cpuinfo" got the result:

The CPU Mhz is 0 !!!!
Strange ... but reboot dom0 seems fix the issue.

On dom0 (CentOS 5.5), the "cat /proc/cpuinfo" got:

I have another Thinkpad x201i which also use CentOS 5.5 to host SLES11 guest and that machine does not has this problem.
Does anyone know what's wrong ? Can change CPU info of guest OS ? Thanks
