[Xen-users] Intel processor model 30 for P6 class family is not supported

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

We have installed Xen version 3.3.1 on CentOS 5.2 32-bit, which runs on a
testbed that has the Intel Jasper Forest processor. When we perform xm dmesg,
we get the following message:

(XEN) xenoprof: Initialization failed. Intel processor model 30 for P6 class
family is not supported

Since this processor has not yet been released, this may explain the
aforementioned message. But we would like to know whether this has any negative
impact on Xen itself(performance, vt-d, etc.) if Xen detects an unknown
processor model like the Jasper Forest. Or is it just informational?

The following is the complete dmesg output:
