Re: [PATCH] Support cpu0-id of Qemu QMP query-sev-capabilities

It allows libvirt to provide the value of cpu0-id retuned by the Qemu QMP command query-sev-capabilities as implemented by the Qemu Patch [1] which is merged to Qemu master branch and should be available with Qemu 7.1. This is used to get the signed Chip Endorsement Key (CEK) of the CPU of AMD system from AMD's Key Distribution Service (KDS). Similar to cbitpos, reducedPhysBits, maxGuests & maxESGuests; the value of cpu0-id is also provided using 'virsh domcapability'.
