Internally we already collect x86 host family + model + stepping
numeric values. This exposed them in capabilities CPU output.
Example:
$ sudo virsh capabilities | grep -A1 -B1 signature
<microcode version='240'/>
<signature family='6' model='94' stepping='3'/>
<counter name='tsc' frequency='3408010000' scaling='no'/>
Users need to know these values to calculate an expected.
SEV-ES/SEV-SNP launch measurement.
