Browse Source 
virtio-mem device would use 'VIRTIO_MEM_F_ACPI_PXM' to add memory to NUMA
node, which MUST be existed, otherwise it will be assigned to node id 0,
even if user specify different node id.

According ACPI spec about Memory Affinity Structure, system hardware
supports hot-add memory region using 'Hot Pluggable | Enabled' flags.
