900289b767 tests: Use DO_TEST_CAPS_LATEST for nvdimm qemuxml2argv
Deprecate DO_TEST to do nvdimm qemuxml2argvdata tests, because
DO_TEST_CAPS_LATEST is a better choice. The DO_TEST needs
to specify all qemu capabilities and is not easy for scaling.

80d1ed9773 conf: Introduce 'alignsize' element into xml for NVDIMM memory
NVDIMM emulation will mmap the backend file, it uses host pagesize

c658764dec qemu: Don't use -mem-prealloc among with .prealloc=yes
https://bugzilla.redhat.com/show_bug.cgi?id=1624223

There are two ways to request memory preallocation on cmd line:
-mem-prealloc and .prealloc attribute for a memory-backend-file.
However, as it turns out it's not safe to use both at the same
time. If -mem-prealloc is used then qemu will fully allocate the
memory (this is done by actually touching every page that has
been allocated). Then, if .prealloc=yes is specified,
mbind(flags = MPOL_MF_STRICT | MPOL_MF_MOVE) is called which:

a) has to (possibly) move the memory to a different NUMA node,
b) can have no effect when hugepages are in play (thus ignoring user
request to place memory on desired NUMA nodes).

Prefer -mem-prealloc as it is more backward compatible
compared to switching to "-numa node,memdev=  + -object
memory-backend-file".

27cc9f6ac1 qemu: process: spice: Pick the first available DRM render node
Up until now, we formatted 'rendernode=' onto QEMU cmdline only if the
user specified it in the XML, otherwise we let QEMU do it for us. This
causes permission issues because by default the /dev/dri/renderDX
permissions are as follows:

crw-rw----. 1 root video

There's literally no reason why it shouldn't be libvirt picking the DRM
render node instead of QEMU, that way (and because we're using
namespaces by default), we can safely relabel the device within the
namespace.

24b74d187c qemu: add memfd source type
Add a new memoryBacking source type "memfd", supported by QEMU (when
the capability is available).

A memfd is a specialized anonymous memory kind. As such, an anonymous
source type could be automatically using a memfd. However, there are
some complications when migrating from different memory backends in
qemu (mainly due to the internal object naming at this point, but
there could be more). For now, it is simpler and safer to simply
introduce a new source type "memfd". Eventually, the "anonymous" type
could learn to use memfd transparently in a separate change.

The main benefits are that it doesn't need to create filesystem files,
and it also enforces sealing, providing a bit more safety.

7ea7342996 conf: correct false boot order error during domain parse
virDomainDefCollectBootOrder() is called for every item on the list
for each type of device. One of the checks it makes is to gather the
order attributes from the <boot> element of all devices, and assure
that no two devices have been given the same order.

Since (internally to libvirt, *not* in the domain XML) an <interface
type='hostdev'> is on both the list of hostdev devices and the list of
network devices, it will be counted twice, and the code that checks
for multiple devices with the same boot order will give a false
positive.

To remedy this, we make sure to return early for hostdev devices that
have a parent.type != NONE.

This was introduced in commit 5b75a4, which was first in libvirt-4.4.0.

614193fac6 conf: Fix check for chardev source path
Attempting to use a chardev definition like

  <serial type='unix'>
    <target type='isa-serial'/>
  </serial>

correctly results in an error being reported, since the source
path - a required piece of information - is missing; however,
the very similar

  <serial type='unix'>
    <target type='pci-serial'/>
  </serial>

was happily accepted by libvirt, only to result in libvirtd
crashing as soon as the guest was started.

The issue was caused by checking the chardev's targetType
against whitelisted values from virDomainChrChannelTargetType
without first checking the chardev's deviceType to make sure
it is actually a channel, for which the check makes sense,
rather than a different type of chardev.

The only reason this wasn't spotted earlier is that the
whitelisted values just so happen to correspond to USB and
PCI serial devices and Xen and UML consoles respectively,
all of which are fairly uncommon.

fe67e3e28e qemu: Validate memory access during validate domain config
Commit 6534b3c4 tried to raise an error when there is no numa
nodes by setting access='shared' in the domain config, but added
a helper called from qemuDomainDeviceDefValidate instead of a
helper called from qemuDomainDefValidate for XML:

  <memoryBacking>
    <hugepages/>
    <access mode='shared'/>
  </memoryBacking>

Since there are no memory devices in the test XML, there would
be no validation failure, but the test added was still failing.
Investigating that it turns out that unnecessary XML elements
were causing the failure (no need for <video>, <graphics>,
<pm>, usb controller model "piix3-uhci", disk attribute for
"discard='unmap'", <serial>, <console>, <channel> and a
memballoon model). Removing all those before moving the method
caused the test to succeed.

So this patch moves the validation to the right place and
removes all the unnecessary XML pieces that were causing
a false validation failure.

hand, so we can only use that one for now, as splitting the capabilities
according to the vendor is a refactor for another day. The need for real
capabilities comes from the extended SEV platform data (PDH, cbitpos,
etc.) we'll need to cache/parse.

0a476f1521 conf: Introduce virDomainDefPostParseMemtune
Previously we were ignoring "nodeset" attribute for hugepage pages
if there was no guest NUMA topology configured in the domain XML.
Commit <fa6bdf6afa878b8d7c5ed71664ee72be8967cdc5> partially fixed
that issue but it introduced a somehow valid regression.

In case that there is no guest NUMA topology configured and the
"nodeset" attribute is set to "0" it was accepted and was working
properly even though it was not completely valid XML.

This patch introduces a workaround that it will ignore the nodeset="0"
only in case that there is no guest NUMA topology in order not to
hit the validation error.

After this commit the following XML configuration is valid:

  <memoryBacking>
    <hugepages>
      <page size='2048' unit='KiB' nodeset='0'/>
    </hugepages>
  </memoryBacking>

but this configuration remains invalid:

  <memoryBacking>
    <hugepages>
      <page size='2048' unit='KiB' nodeset='0'/>
      <page size='1048576' unit='KiB'/>
    </hugepages>
  </memoryBacking>

The issue with the second configuration is that it was originally
working, however changing the order of the <page> elements resolved
into using different page size for the guest.  The code is written
in a way that it expect only one page configured and always uses only
the first page in case that there is no guest NUMA topology configured.
See qemuBuildMemPathStr() function for details.

This use-case was broken by commit

We allowed this configuration and it was working as expected therefore
we can consider it as regression.  We should have never allowed such

silently ignore the 'nodeset' attribute if it's set to '0'.

Move the call back after formatting all disks and reiterate the disks to
find the floppy controllers.

This also moves the '-global' directive which sets up the default
ISA-FDC to the end after all the disks but since we are modifying the

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,

Therefore introduce a new, effectively a 'disable', type for video

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.

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
