Re: [Xen-devel] Xen HVM cpuid problem

Hi Keir,

For HVM guests, all cpuid Fn's going through domain_cpuid()
iterate over the loop and then return 0 for all four registers.


This loop return 0 to all four registers, if there is no cpuid configuration for this input.


To reproduce this, cpuid is NOT explicitely configured
in the guest config file.

What do you would like to say by "NOT explicitly configured" ? Could you please give us an example ?


BTW: Is there a reason for not handling cpuid in one central place?


Yes, there is, because cpuid havn't exactly the same behavior under intel and amd.
