VirtIO Devices
|
|
==============
|
|
|
|
VirtIO devices are paravirtualized devices designed to be efficient to
|
|
emulate and virtualize. Unless you are specifically trying to exercise
|
|
a driver for some particular hardware they are the recommended device
|
|
models to use for virtual machines.
|
|
|
|
The `VirtIO specification`_ is an open standard managed by OASIS. It
|
|
describes how a *driver* in a guest operating system interacts with
|
|
the *device* model provided by QEMU. Multiple Operating Systems
|
|
support drivers for VirtIO with Linux perhaps having the widest range
|
|
of device types supported.
|
|
|
|
The device implementation can either be provided wholly by QEMU, or in
|
|
concert with the kernel (known as *vhost*). The device implementation
|
|
can also be off-loaded to an external process via :ref:`vhost user
|
|
<vhost_user>`.
