54 supported; this is referred to as hardware-assisted virtualization (HVM and PVH).
56 peripherals, or para-virtualized drivers, which are aware of virtualization,
57 and hence able to optimize certain behaviors to improve performance or
59 PVH configurations rely on para-virtualized drivers exclusively for IO.
