Re: [libvirt] [Qemu-devel] [RFC 0/5] Allow object-add on X86CPU subclasses, for CPU model probing

This series allows management code to use object-add on X86CPU subclasses, so it

can use it to probe for CPU model information without re-running QEMU. The main use case for this is to allow management code to create CPU objects and query the "feature-words" and "filtered-features" properties on the new objects, to find out which features each CPU model needs, and to do the same using the "host" CPU model to check which features can be enabled in a given host. There's experimental libvirt code to use the new command at: https://github.com/ehabkost/libvirt/tree/work/cpu-feature-word-query The experimental code just create the CPU objects to query for feature information, but doesn't do anything with that data.
