[Xen-devel] Possible Bug in CPU detection / clock skew?

[Alexander Wilms <alex.wilms@xxxxxxxxxxxxx>]

Hi all,

I have a very strange clock skew problem on my Server since running Xen 3.0.3 
that I have never seen before on the same machine running Xen 2.0.x.

Now I compared boot messages from the old and new installation and I saw a 
huge difference in the reported CPU speeds under 3.0.3 hypervisor. Could this 
be a reason for the clock skew? Excuse me if the question is stupid, I'm not 
a CPU expert...

Xen 2.0.x:
Boot1: <6>Xen reported: 498.762 MHz processor

Boot2: <6>Xen reported: 498.765 MHz processor

Xen 3.0.3:

Boot1: <6>Xen reported: 556.714 MHz processor

Boot2: <6>Xen reported: 621.840 MHz processor

Hardware is a Dual CPU Intel 440BX Server Board with 2 PIII 500 Cpu's (I know, 
it's veery oooold...)

Thanks,
Alex
