11 What's VirtIO?
13 VirtIO is a virtualization standard for network and disk device drivers where
22 VirtIO can use various different buses, aka transports as described in the
23 spec. While VirtIO devices are commonly implemented as PCI devices on x86,

31 The VirtIO spec defines a lots of VirtIO device types, however at present only
