9.4. System Devices

System devices are critical for the guest to run and cannot be removed. Each system device attached to a guest also takes up an available PCI slot. The default system devices are:

the host bridge,
the ISA bridge and USB bridge (The USB and ISA bridges are the same device),
the graphics card (using either the Cirrus or qxl driver), and
the memory balloon device.
