Hi ,

I'm looking for a possibility to simulate a VM (to be used as a host) reporting no or empty NUMA <cells> in 'virsh capabilities'. 'virsh capabilities' usually reports single NUMA in the VMs, like <numa> <cell id='0' cpus='0-63' memory='16777216' unit='KiB'/> </numa>

If the "host" doesn't report any NUMA topology, the libvirt will always synthesize a single NUMA cell. So there is no scenario in which the <numa> info will be empty with current generation libvirt.
