Host bridge emulation is based on PCI emulation; however, the host bridge
emulation only sets the PCI configuration space. The Device Model (DM) sets the
PCI configuration space for hostbridge in the Service VM and then exposes it to
the User VM to detect the PCI hostbridge.

PCI Host Bridge and Hierarchy

There is PCI host bridge emulation in DM. The bus hierarchy is determined by ``acrn-dm`` command line input. Using this command line, as an example::
For PCI host bridge emulation, the bus hierarchy is determined by ``acrn-dm``
command line input. Using this command line, as an example::
acrn-dm -m $mem_size -s 0:0,hostbridge \
