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.
