Device Emulation
|
||||
----------------
|
||||
|
||||
QEMU supports the emulation of a large number of devices from
|
||||
peripherals such network cards and USB devices to integrated systems
|
||||
on a chip (SoCs). Configuration of these is often a source of
|
||||
confusion so it helps to have an understanding of some of the terms
|
||||
used to describes devices within QEMU.
|
||||
|
||||
Common Terms
|
||||
~~~~~~~~~~~~
|
||||
|
||||
Device Front End
|
||||
================
|
||||
|
||||
A device front end is how a device is presented to the guest. The type
|
||||
of device presented should match the hardware that the guest operating
|
||||
system is expecting to see. All devices can be specified with the
|
||||
``--device`` command line option. Running QEMU with the command line
|
||||
options ``--device help`` will list all devices it is aware of. Using
|
||||
the command line ``--device foo,help`` will list the additional
|
||||
configuration options available for that device.
|
||||
|
||||
A front end is often paired with a back end, which describes how the
|
||||
host's resources are used in the emulation.
|
||||
|
||||
Device Buses
|
||||
============
|
||||
|
||||
Most devices will exist on a BUS of some sort. Depending on the
|
||||
machine model you choose (``-M foo``) a number of buses will have been
|
||||
automatically created. In most cases the BUS a device is attached to
|
||||
can be inferred, for example PCI devices are generally automatically
|
||||
allocated to the next free address of first PCI bus found. However in
|
||||
complicated configurations you can explicitly specify what bus
|
||||
(``bus=ID``) a device is attached to along with its address
|
||||
(``addr=N``).
|
||||
|
||||
Some devices, for example a PCI SCSI host controller, will add an
|
||||
additional buses to the system that other devices can be attached to.
|
||||
A hypothetical chain of devices might look like:
|
||||
|
||||
--device foo,bus=pci.0,addr=0,id=foo
|
||||
--device bar,bus=foo.0,addr=1,id=baz
|
||||
|
||||
which would be a bar device (with the ID of baz) which is attached to
|
||||
the first foo bus (foo.0) at address 1. The foo device which provides
|
||||
that bus is itself is attached to the first PCI bus (pci.0).
|
||||
|
||||
|
||||
Device Back End
|
||||
===============
|
||||
|
||||
The back end describes how the data from the emulated device will be
|
||||
processed by QEMU. The configuration of the back end is usually
|
||||
specific to the class of device being emulated. For example serial
|
||||
devices will be backed by a ``--chardev`` which can redirect the data
|
||||
to a file or socket or some other system. Storage devices are handled
|
||||
by ``--blockdev`` which will specify how blocks are handled, for
|
||||
example being stored in a qcow2 file or accessing a raw host disk
|
||||
partition. Back ends can sometimes be stacked to implement features
|
||||
like snapshots.
|
||||
|
||||
While the choice of back end is generally transparent to the guest,
|
||||
there are cases where features will not be reported to the guest if
|
||||
the back end is unable to support it.
|

Device Pass Through
|
||||
===================
|
||||
|
||||
Device pass through is where the device is actually given access to
|
||||
the underlying hardware. This can be as simple as exposing a single
|
||||
USB device on the host system to the guest or dedicating a video card
|
||||
in a PCI slot to the exclusive use of the guest.

vhost-user back ends
|
||||
--------------------
|
||||
|
||||
vhost-user back ends are way to service the request of VirtIO devices
|
||||
outside of QEMU itself. To do this there are a number of things
|
||||
required.
|
||||
|
||||
vhost-user device
|
||||
===================
|
||||
|
||||
These are simple stub devices that ensure the VirtIO device is visible
|
||||
to the guest. The code is mostly boilerplate although each device has
|
||||
a ``chardev`` option which specifies the ID of the ``--chardev``
|
||||
device that connects via a socket to the vhost-user *daemon*.
|
||||
|
||||
vhost-user daemon
|
||||
=================
|
||||
|
||||
This is a separate process that is connected to by QEMU via a socket
|
||||
following the :ref:`vhost_user_proto`. There are a number of daemons
|
||||
that can be built when enabled by the project although any daemon that
|
||||
meets the specification for a given device can be used.
|
||||
|
||||
Shared memory object
|
||||
====================
|
||||
|
||||
In order for the daemon to access the VirtIO queues to process the
|
||||
requests it needs access to the guest's address space. This is
|
||||
achieved via the ``memory-backend-file`` or ``memory-backend-memfd``
|
||||
objects. A reference to a file-descriptor which can access this object
|
||||
will be passed via the socket as part of the protocol negotiation.
|
||||
|
||||
Currently the shared memory object needs to match the size of the main
|
||||
system memory as defined by the ``-m`` argument.
|
||||
|
||||
Example
|
||||
=======
|
||||
|
||||
First start you daemon.
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
$ virtio-foo --socket-path=/var/run/foo.sock $OTHER_ARGS
|
||||
|
||||
The you start your QEMU instance specifying the device, chardev and
|
||||
memory objects.
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
$ |qemu_system| \\
|
||||
-m 4096 \\
|
||||
-chardev socket,id=ba1,path=/var/run/foo.sock \\
|
||||
-device vhost-user-foo,chardev=ba1,$OTHER_ARGS \\
|
||||
-object memory-backend-memfd,id=mem,size=4G,share=on \\
