d947fa8a08 conf: Introduce firmware attribute to <os/>
The idea is that using this attribute users enable libvirt to
automagically select firmware image for their domain. For
instance:

  <os firmware='efi'>
    <type arch='x86_64' machine='pc-q35-4.0'>hvm</type>
    <loader secure='no'/>
  </os>

  <os firmware='bios'>
    <type arch='x86_64' machine='pc-q35-4.0'>hvm</type>
  </os>

(The automagic of selecting firmware image will be described in
later commits.)

Accepted values are 'bios' and 'efi' to let libvirt select
corresponding type of firmware.

I know it is a good sign to introduce xml2xml test case when
changing XML config parser but that will have to come later.
Firmware auto selection is not enabled for any driver just yet so
any xml2xml test would fail right away.

cdd592553a virDomainLoaderDefParseXML: Allow loader path to be NULL
Except not really. At least for now.

In the future, the firmware will be selected automagically.
Therefore, it makes no sense to require the pathname of a
specific firmware binary in the domain XML. But since it is not
implemented do not really allow the path to be NULL. Only move
code around to prepare it for further expansion.

* "virtio-transitional" maps to qemu "virtio-scsi-pci-transitional"
* "virtio-non-transitional" maps to qemu "virtio-scsi-non-transitional"

The naming here doesn't match the pre-existing model=virtio-scsi.
The prescence of '-scsi' there seems kind of redundant as we have
type='scsi' already, so I decided to follow the pattern of other
patches and use virtio-transitional etc.

qemu vhost-scsi devices map to XML roughly like:

    <hostdev mode='subsystem' type='scsi_host'>

To support vhost-scsi-pci-{non-}traditional in qemu, we
need to to extend the SCSI Host hostdev XML to handle
model= value. This matches the XML model= format used
for mediated devices. This is just the domain_conf bits
and some XML test cases.

Use of virtio-X naming here does not match the hostdev
protocol=vhost nor does it match the qemu vhost-X device
naming, however it's more consistent with all other
model= names in this area, and also matches the
inconsistency of <vsock> devices which use model=virtio
but map to vhost-vsock on the qemu commandline

ae05211a36 network: set firewalld zone of bridges to "libvirt" zone when appropriate
This patch restores broken guest network connectivity after a host
firewalld is switched to using an nftables backend. It does this by
adding libvirt networks' bridge interfaces to the new "libvirt" zone
in firewalld.

After this patch, the bridge interface of any network created by
libvirt (when firewalld is active) will be added to the firewalld
zone called "libvirt" if it exists (regardless of the firewalld
backend setting). This behavior does *not* depend on whether or not
libvirt has installed the libvirt zone file (set with
"--with[out]-firewalld-zone" during the configure phase of the package
build).

If the libvirt zone doesn't exist (either because the package was
configured to not install it, or possibly it was installed, but
firewalld doesn't support rule priorities, resulting in a parse
error), the bridge will remain in firewalld's default zone, which
could be innocuous (in the case that the firewalld backend is
iptables, guest networking will still function properly with the
bridge in the default zone), or it could be disastrous (if the
firewalld backend is nftables, we can be assured that guest networking
will fail). In order to be unobtrusive in the former case, and
informative in the latter, when the libvirt zone doesn't exist we
then check the firewalld version to see if it's new enough to support
the nftables backend, and then if the backend is actually set to
nftables, before logging an error (and failing the net-start
operation, since the network couldn't possibly work anyway).

When the libvirt zone is used, network behavior is *slightly*
different from behavior of previous libvirt. In the past, libvirt
network behavior would be affected by the configuration of firewalld's
default zone (usually "public"), but now it is affected only by the
"libvirt" zone), and thus almost surely warrants a release note for
any distro upgrading to libvirt 5.1 or above. Although it's
unfortunate that we have to deal with a mandatory behavior change, the
architecture of multiple hooks makes it impossible to *not* change
behavior in some way, and the new behavior is arguably better (since
it will now be possible to manage access to the host from virtual
machines vs from public interfaces separately).

07c9d6601d qemu: use line breaks in command line args written to log
The QEMU command line arguments are very long and currently all written
on a single line to /var/log/libvirt/qemu/$GUEST.log. This introduces
logic to add line breaks after every env variable and "-" optional

600462834f Remove all Author(s): lines from source file headers
In many files there are header comments that contain an Author:
statement, supposedly reflecting who originally wrote the code.
In a large collaborative project like libvirt, any non-trivial
file will have been modified by a large number of different
contributors. IOW, the Author: comments are quickly out of date,
omitting people who have made significant contribitions.

In some places Author: lines have been added despite the person
merely being responsible for creating the file by moving existing
code out of another file. IOW, the Author: lines give an incorrect
record of authorship.

With this all in mind, the comments are useless as a means to identify
who to talk to about code in a particular file. Contributors will always
be better off using 'git log' and 'git blame' if they need to  find the
author of a particular bit of code.

This commit thus deletes all Author: comments from the source and adds
a rule to prevent them reappearing.

The Copyright headers are similarly misleading and inaccurate, however,
we cannot delete these as they have legal meaning, despite being largely
inaccurate. In addition only the copyright holder is permitted to change
their respective copyright statement.

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.

4f1107614d docs: Enhance polkit documentation to describe secondary connection
https://bugzilla.redhat.com/show_bug.cgi?id=1631606

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
names used for each 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'>

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.

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.

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).

The launch-security element can be used to define the security

When 'sev' is used, the VM will be launched with AMD SEV feature enabled.
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.

1bd5a08d38 conf, schema, docs: Add support for TSEG size setting
TSEG (Top of Memory Segment) is one of many regions that SMM (System Management
Mode) can occupy.  This one, however is special, because a) most of the SMM code
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.

The old behaviour was bhyve -c C, where C is a number of vCPUs, is

So if we have CPU topology in the domain XML, use the new syntax,
otherwise keep the old behaviour.
