We need to provide support for CPU ID masking. Xen and VMware ESX are examples of current hypervisors which support such masking.
My proposal is to define new 'cpuid' feature advertised in guest capabilities: ... <domain type='xen' id='42'> ... <features> <pae/> <acpi/> <apic/> <cpuid> <mask level='1' register='ebx'> xxxx:xxxx:0000:1010:xxxx:xxxx:xxxx:xxxx </mask> ... What are your opinions about this?
I think it's too low-level, and the structure is x86-specific.
Hmm, right, it's only for x86... I'll come up with something better. Jirka
