Is it no-go to start throwaway qemu on the new domain creation time?
i.e. user create a new domain, with specific -machine/-smp layout
libvirt stores results of query-hotpluggable-cpus and then allow user
in (eg)virt-manager to pick which CPUs are enabled and optionally to
which numa nodes they are mapped.
