RE: [Xen-devel] Intel processor model 30 for P6 class family is not supported

["Nguyen, Daniel" <Daniel.Nguyen@xxxxxxx>]

Thanks for your prompt response.

But we are still concerned about the statement "Initialization failed". Could 
you elaborate on that a little bit more as to what kind of initialization has 
failed? If it's just informational, then "Initialization failed" can be quite 
an intimidating statement to be printed out.

Second question would be whether you know when Jasper Forest or model 30 will 
be recognized by Xen.

Any help is again greatly appreciated,
Daniel

It's just informational. Most CPU features are probed via CPUID. It's just
xenoprof that cares deeply about the family/model numbers.
