aca7ff5f70 libxl: add support for PVH
Since this is something between PV and HVM, it makes sense to put the
setting in place where domain type is specified.
To enable it, use <os><type machine="xenpvh">xenpvh</type></os>. It is
also included in capabilities.xml, for every supported HVM guest type - it
doesn't seems to be any other requirement (besides new enough Xen).

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.

Since commit 8259255 usage of a primary connection driver for
a virConnect has been modified to open (virConnectOpen) and use
a connection to the specific driver in order to handle the API
calls to/for that driver. This causes some confusion and issues
for ACL polkit rule scripts to know exactly which driver by
name will be used.

Add some documentation describing the processing of the primary
and secondary connection as well as the list of the connect_driver

6af8417415 conf: Introduce RDT monitor host capability
This patch is introducing cache monitor(CMT) to cache and
memory bandwidth monitor(MBM) for monitoring CPU memory
bandwidth.

The host capability of the two monitors is also introduced
in this patch.

For CMT, the host capability is shown like:
  <host>
  ...
    <cache>
      <bank id='0' level='3' type='both' size='15' unit='MiB' cpus='0-5'>
        <control granularity='768' min='1536' unit='KiB' type='both' maxAllocs='4'/>
      </bank>
      <monitor level='3' 'reuseThreshold'='270336' maxMonitors='176'>
        <feature name='llc_occupancy'/>
      </monitor>
    </cache>
    ...
  </host>

For MBM, the capability is shown like this:
  <host>
    ...
    <memory_bandwidth>
      <node id='1' cpus='6-11'>
        <control granularity='10' min ='10' maxAllocs='4'/>
      </node>
      <monitor maxMonitors='176'>
        <feature name='mbm_total_bytes'/>
        <feature name='mbm_local_bytes'/>
      </monitor>
    </memory_bandwidth>

5bdcef13d1 libxl: drop support for Xen < 4.6
Currently the libxl driver claims support for Xen >= 4.4, but
Xen 4.4 and 4.5 are no longer supported upstream. Let's increase
the minimum supported Xen version to 4.6 and change the defined
LIBXL_API_VERSION to 0x040500, which is the API version defined
when Xen 4.6 was released.

Since Xen 4.6 contains a pkgconfig file, drop the now unused code
that falls back to using LIBVIRT_CHECK_LIB in the absence of
pkgconfig file. In addition, bumping the LIBXL_API_VERSION
required adjusting the calls to libxl_set_vcpuaffinity to account
for the extra parameter in the 0x040500 version of the API.

cfdc0c771a Forget last daemon/ dir artefacts
The most important part is LIBVIRTD_PATH env var fix. It is used
in virFileFindResourceFull() from tests. The libvirtd no longer
lives under daemon/.

Then, libvirtd-fail test was still failing (as expected) but not
because of missing config file but because it was trying to
execute (nonexistent) top_builddir/daemon/libvirtd which
fulfilled expected outcome and thus test did not fail.

Thirdly, lcov was told to generate coverage for daemon/ dir too.

Fourthly, our compiling documentation was still suggesting to run
daemonn/libvirtd.

And finally, some comments in a systemtap file and a probes file
were still referring to daemon/libvirtd.

6c0d0210cb src: Make virStr*cpy*() functions return an int
Currently, the functions return a pointer to the
destination buffer on success or NULL on failure.

Not only does this kind of error handling look quite
alien in the context of libvirt, where most functions
return zero on success and a negative int on failure,
but it's also somewhat pointless because unless there's
been a failure the returned pointer will be the same
one passed in by the user, thus offering no additional
value.

Change the functions so that they return an int
instead.

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.

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).

SEV feature supports running encrypted VM under the control of KVM.
Encrypted VMs have their pages (code and data) secured such that only the
guest itself has access to the unencrypted version. Each encrypted VM is
associated with a unique encryption key; if its data is accessed to a
different entity using a different key the encrypted guests data will be
incorrectly decrypted, leading to unintelligible data.

TSEG (Top of Memory Segment) is one of many regions that SMM (System Management

lives in TSEG nowadays and b) QEMU just (well, some time ago) added support for
so called 'extended' TSEG.  The difference to the TSEG implemented in real q35's
MCH (Memory Controller Hub) is that it can offer one extra size to the guest OS
apart from the standard TSEG's 1, 2, and 8 MiB and that size can be selected in
1 MiB increments.  Maximum may vary based on QEMU and is way too big, so we
don't need to check for the maximum here.  Similarly to the memory size we'll
leave it to the hypervisor to try satisfying that and giving us an error message
in case it is not possible.

Commit id '02129b7c0' added a single pagesElem for slightly

listing and the other for NUMA supported page sizes. For the
former, only the pages unit and size are formatted, while for
the latter the pages unit, size, and availability data is formatted.

The virt-xml-validate would fail because it expected something
extra in the host page size output. So split up pagesElem a bit
and create pagesHost and pagesNuma for the differences.

Modify some capabilityschemadata output to have the output - even
though the results may not be realistic with respect to the
original incarnation of the data.

b50efe97ad conf: Add VM Generation ID parse/format support
The VM Generation ID is a mechanism to provide a unique 128-bit,
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.

Convert it to tristate. For writing XML this is semanticly the same,
<vmcoreinfo/> is processed as <vmcoreinfo state='on'/>.

For apps reading guest XML this is technically an API change,
as they might misinterpret <vmcoreinfo state='off'/>, however this
has only been present in libvirt since 3.10.0 and I don't think any

Currently the virDrvConnectOpen method is supposed to handle both
opening an explicit URI and auto-probing a driver if no URI is
given. Introduce a dedicated virDrvConnectURIProbe method to enable the
probing functionality to be split from the driver opening functionality.

It is still possible for NULL to be passed to the virDrvConnectOpen
method after this change, because the remote driver needs special
handling to enable probing of the URI against a remote libvirtd daemon.

Historically we have used a bare lxc:/// URI for connecting to LXC. This
is different from our practice with QEMU, UML, Parallels, Libxl, BHyve
and VirtualBox drivers, which all use a path of '/system' or '/session'
or both.

By making LXC allow '/system', we have fully standardized on the use of
either '/system' or '/session' for all the stateful drivers that run
inside libvirtd.

a8ea89d258 xen: encourage use of xen:///system URI as preferred format
Historically we have used a bare xen:/// URI for connecting to the
legacy Xen driver. The new libxl Xen driver follows the new practice
of allowing '/system' as a path, as well as bare '/' for compat with
the old Xen driver.

This documents xen:///system as the preferred format for Xen, leaving
xen:/// as an undocumented feature just for back-compat.

898edc9617 conf: Prefer pcie-to-pci-bridge to dmi-to-pci-bridge
Both pcie-to-pci-bridge and dmi-to-pci-bridge can be used to
create a traditional PCI topology in a pure PCIe guest such as
those using the x86_64/q35 or aarch64/virt machine type;
however, the former should be preferred, as it doesn't need to
obey limitation of real hardware and is completely
architecture-agnostic.

will get an error. Document this fact.

c8fec25692 conf: Add support for setting Chassis SMBIOS data fields
This type of information defines attributes of a system
chassis, such as SMBIOS Chassis Asset Tag.

access inside VM (for example)
Linux:   /sys/class/dmi/id/chassis_asset_tag.
Windows: (Get-WmiObject Win32_SystemEnclosure).SMBIOSAssetTag
          wirhin Windows PowerShell.

As an example, add the following to the guest XML

    <chassis>
      <entry name='manufacturer'>Dell Inc.</entry>
      <entry name='version'>2.12</entry>
      <entry name='serial'>65X0XF2</entry>

12bc2b817f Revert "qemu: Expose rx/tx_queue_size in qemu.conf too"
This reverts commit 038eb472a0.

On reflection adding defaults for arbitrary guest XML device config
settings to the qemu.conf is not a sustainable path. Removing the
support for rx/tx queue size so that it doesn't set a bad precedent.

d64d5ccb06 docs: document requirement to provide Signed-off-by lines for DCO
Document that contributors are required to assert compliance with the
Developers Certification of Origin 1.1, by providing Signed-off-by tags
for all commit messages. The DCO is formally stating what we have long
implicitly expected of contributors in terms of their legal rights to
make the contribution. This puts the project in a stronger position
should any questions around contributions be raised going forward in the
future.

038eb472a0 qemu: Expose rx/tx_queue_size in qemu.conf too
In 2074ef6cd4 and c56cdf259 (and friends) we've added two
attributes to virtio NICs: rx_queue_size and tx_queue_size.
However, sysadmins might want to set these on per-host basis but
don't necessarily have an access to domain XML (e.g. because they
are generated by some other app). So let's expose them under
qemu.conf (the settings from domain XML still take precedence as
they are more specific ones).
