Howto read MSR thermal under XEN-4.15.0

[Bobbi Sanchez <bobbisanchez@xxxxxx>]

Hi,

how can i read the MSR Thermal Values under XEN-4.15.0 ?

Usually without having XEN-4.15.0 installed i can read the MSR Thermal Values 
like this:

rdmsr -p 0 -d -f22:16 0x19c

this works for my Core2Quod Q6600.

But after having xen-4.15.0 installed and booted, same command shows now: 0


Best Regards
