on top of this we need to check that configuring via
QAPI works as well.

Add an extra test as a separate patch on top,
building the same topology (so we could reuse the same reference tables)
using set-numa-node/--preconfig.

See pc_dynamic_cpu_cfg() and for example how to use set-numa-node
over QMP.
