I started figuring out how to add support for this to libvirt and discovered a few problems that made it not-easy to use for management.
Patch 1 adds a witness to allow us to properly detect the support for the feature. Patches 2 and 3 are two options to fix discrepancy between names that need to be used with -device and those reported by query-hotpluggable-cpus.
