Hi, libvirt-users
How could I set up a memory-only and no-cpu NUMA node for the qemu-VM with
the XML file?
Seems each NUMA cell has to be bundled with some specific cpuids.
If I write the element like this, it is wrong.
<cpu mode='host-passthrough'>
<numa>
<cell id='0' cpus='0-3' memory='16' unit='GiB'/>
<cell id='1' cpus='*null*' memory='16' unit='GiB'/>
</numa>
</cpu>
Also if I ignore the cpus item, it is not acceptable for the virsh command.
The reason I want the memory-only node is that I want to set up multiple
memory tiers for the VM, just like

Thank You
