Here you have:
- 2 NUMA nodes for the guest, 0 and 1. (both mapped to the same NUMA node in host, but you can and should put it in different host NUMA nodes)

==============
The PXB is composed by:
- HostBridge (TYPE_PXB_HOST)
- The host bridge allows to register and query the PXB's rPCI root bus in QEMU.
+ The host bridge allows to register and query the PXB's PCI root bus in QEMU.
- PXBDev(TYPE_PXB_DEVICE)
It is a regular PCI Device that resides on the piix host-bridge bus and its bus uses the same PCI domain.
However, the bus behind is exposed through ACPI as a primary PCI bus and starts a new PCI hierarchy.
