d48813e81a conf: Introduce new video type 'none'
Historically, we've always enabled an emulated video device every time we
see that graphics should be supported with a guest. With the appearance
of mediated devices which can support QEMU's vfio-display capability,
users might want to use such a device as the only video device.
Therefore introduce a new, effectively a 'disable', type for video
device.

c0ca6dcf42 qemu: command: Enable formatting vfio-pci.display option onto cmdline
Since QEMU 2.12, QEMU understands a new vfio-pci device option 'display'
which can be used to turn on display capabilities on vgpu-enabled
mediated devices, IOW emulated GPU devices like QXL will no longer be
needed with vgpu-enable mdevs.
QEMU defaults to 'auto' for the 'display' attribute, which is not
foolproof, so we need to play it safe here and default to display='off'
if this attribute wasn't provided in the XML explicitly.

d54e45b6ed conf: Introduce new <hostdev> attribute 'display'
QEMU 2.12 introduced a new type of display for mediated devices using
vfio-pci backend which allows a mediated device to be used as a VGA
compatible device as an alternative to an emulated video device. QEMU
exposes this feature via a vfio device property 'display' with supported
values 'on/off/auto' (libvirt will default to 'off').

This patch adds the necessary bits to domain config handling in order to
expose this feature. Since there's no convenient way for libvirt to come
up with usable defaults for the display setting, simply because libvirt
is not able to figure out which of the display implementations - dma-buf
which requires OpenGL support vs vfio regions which doesn't need OpenGL
(works with OpenGL enabled too) - the underlying mdev uses.

d8266ebe16 qemu: Introduce a new graphics display type 'headless'
Since 2.10 QEMU supports a new display type egl-headless which uses the
drm nodes for OpenGL rendering copying back the rendered bits back to
QEMU into a dma-buf which can be accessed by standard "display" apps
like VNC or SPICE. Although this display type can be used on its own,
for any practical use case it makes sense to pair it with either VNC or
SPICE display. The clear benefit of this display is that VNC gains
OpenGL support, which it natively doesn't have, and SPICE gains remote
OpenGL support (native OpenGL support only works locally through a UNIX
socket, i.e. listen type=socket/none).

ff767f083f qemu: command: Fix building of the SDL display command line
QEMU uses a shorthand '-sdl' which maps to '-display sdl'. However, if
there are any options to be passed to SDL, the full command version must
be used. Everything seemingly worked for us until commit 5038b30043
introduced OpenGL support for SDL and added ',gl=on/off' option which as
mentioned above could have never worked with the shorthand version of
the command. Indeed starting a domain with an SDL display and OpenGL
enabled, QEMU produces a rather cryptic error:

-sdl: Could not open 'gl=on': No such file or directory

This patch provides fixes to both the SDL cmdline generation and the
test suite.

ed5aa85f37 qemu: don't use chardev FD passing for vhostuser backend
QEMU chardevs have a bug which makes the vhostuser backend complain
about lack of support for FD passing when validating the chardev.
While this is ultimately QEMU's responsibility to fix, libvirt needs to
avoid tickling the bug.

Simply disabling chardev FD passing just for vhostuser's chardev is
the most prudent approach, avoiding need for a QEMU version number
check.

b340c6c614 qemu: format serial and geometry on frontend disk device
Currently we format the serial, geometry and error policy on the -drive
backend argument.

QEMU added the ability to set serial and geometry on the frontend in
the 1.2 release deprecating use of -drive, with support being deleted
from -drive in 3.0.

We keep formatting error policy on -drive for now, because we don't
ahve support for that with -device for usb-storage just yet.

Note that some disk buses (sd) still don't support -device. Although
QEMU allowed these properties to be set on -drive for if=sd, they
have been ignored so we now report an error in this case.

30fb2276d8 qemu: support passing pre-opened UNIX socket listen FD
There is a race condition when spawning QEMU where libvirt has spawned
QEMU but the monitor socket is not yet open. Libvirt has to repeatedly
try to connect() to QEMU's monitor until eventually it succeeds, or
times out. We use kill() to check if QEMU is still alive so we avoid
waiting a long time if QEMU exited, but having a timeout at all is still
unpleasant.

With QEMU 2.12 we can pass in a pre-opened FD for UNIX domain or TCP
sockets. If libvirt has called bind() and listen() on this FD, then we
have a guarantee that libvirt can immediately call connect() and
succeed without any race.

Although we only really care about this for the monitor socket and agent
socket, this patch does FD passing for all UNIX socket based character
devices since there appears to be no downside to it.

We don't do FD passing for TCP sockets, however, because it is only
possible to pass a single FD, while some hostnames may require listening
on multiple FDs to cover IPv4 and IPv6 concurrently.

cryptographically random, and integer value identifier known as
the GUID (Globally Unique Identifier) to the guest OS. The value
is used to help notify the guest operating system when the virtual
machine is executed with a different configuration.

This patch adds support for a new "genid" XML element similar to
the "uuid" element. The "genid" element can have two forms "<genid/>"
or "<genid>$GUID</genid>". If the $GUID is not provided, libvirt
will generate one and save it in the XML.

Since adding support for a generated GUID (or UUID like) value to
be displayed modifying the xml2xml test to include virrandommock.so
is necessary since it will generate a "known" value.

2c4affd57e qemu: Implement memoryBacking/discard
https://bugzilla.redhat.com/show_bug.cgi?id=1480668

QEMU has this new feature memory-backend-file.discard-data=yes
which is a nifty optimization. Basically, when qemu is quitting
or on memory hotplug it calls munmap() and close() on the file
that is backing the memory. However, this does not mean kernel
won't stop touching that part of memory. It still might. With
this feature enabled we tell kernel: "we don't need this memory
nor data stored in it". This makes kernel drop the memory
immediately without trying to sync memory with the mapped file.

Unfortunately, this cannot be turned on by default because we
can't be sure when users really don't care about what happens to
data after qemu dies. So it has to be opt-in. As usual, there are
three places where one can configure memory attributes. This
patch adds the feature to all of them.

Up until now we have only formatted non-default GIC versions on

QEMU versions that didn't implement the gic-version option to

QEMU versions, where the option is available. Moreover, having
the GIC version formatted on the command line at all times
ensures that QEMU changing its own defaults doesn't affect the
ABI of libvirt guests.

A few test cases are removed to avoid extra churn. It doesn't
matter for coverage, as those scenarios are already covered by
other parts of the test suite.
