Is there a reason why this uses 'device_add' rather than the 'cpu_add'
command? Libvirt uses two separate approaches already. Due to legacy
reasons we support the HMP 'cpu_set' command, and lately we added
support for QMP 'cpu-add'. Using device_add here will introduce a
different approach and will require yet another compatibility layer in
libvirt to support this.
