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.

Daniel
