Using virtio-blk with SEV on host kernels prior to 5.1 didn't work

Since docs generated from RST by docutils have a '<div class='document'
id='$DOCNAME>' we actually don't need an extra wrapper for them.
Additionally if we standardize on one of them we can use the same styles
for both. I've picked the latter because it makes more sense to use the
document name as 'id'.
This patch:
1) Modifies the XSL trasformation to add the wrapper only if it's not
present.
2) Modifies the XSL transformation to use 'id' for document name and
class='document' for the wrapper element.
3) Changes docs.html/index.html/hvsupport.html to use 'id' instead of

This patch adds new schema and adds support for parsing and formatting
domain configurations that include vdpa devices.
vDPA network devices allow high-performance networking in a virtual
machine by providing a wire-speed data path. These devices require a
vendor-specific host driver but the data path follows the virtio
specification.
When a device on the host is bound to an appropriate vendor-specific
driver, it will create a chardev on the host at e.g. /dev/vhost-vdpa-0.
That chardev path can then be used to define a new interface with
type='vdpa'.

Meson unfortunately doesn't give us any means to share the code using
xsltproc to output HTMLs processed by our template. This means we will
have to resort to copy&paste engineering.
To make things simpler, let's use the same block of code in
docs/meson.build but also any of the subdirs which generate htmls.
This will be achieved by making it configurable and wrapping it in a
comment that instructs anybody editing it to keep it identical.
We need to be able to configure the template file used and installation
directory. The rest of the processing is same as we do in
docs/meson.build.

Since we no longer reformat the XSLT-transformed files, there's no need
to use an external script any more.
Unfortunately this hid errors from 'xsltproc' as return value was not
checked and the stderr was piped into xmllints stdin. The result was
that any invalid input file would result into an empty output file.
Since the script's only purpose was to prevent additional temporary
files at the time we were reformatting the output in a pipeline we no
longer need this.
Moving the generation directly into the meson definition makes it more
obvious what's happening and saves readers from having to parse what's
going on. A free bonus is that errors are now properly caught and
reported.

These XML attributes have been mandatory since the introduction of SEV
support to libvirt. This design decision was based on QEMU's
requirement for these to be mandatory for migration purposes, as
differences in these values across platforms must result in the
pre-migration checks failing (not that migration with SEV works at the
time of this patch).
Expecting the user to specify these is cumbersome and the same XML
cannot be re-used across different revisions of SEV. Since
we have SEV platform information saved in QEMU capabilities, we can
make the attributes optional and should fill them in automatically
in the QEMU driver right before starting it.

Hyper-V version numbers are not compatible with the encoding in

For example, the Windows Server 2016 Hyper-V version is 10.0.14393: its
micro is over 14 times larger than the encoding allows.
This commit repacks the Hyper-V version number in order to preserve all
of the digits. The major and minor are concatenated (with minor zero-
padded to two digits) to form the repacked major value. This works
because Microsoft's major and minor versions numbers are unlikely to
exceed 99. The repacked minor value is derived from the digits in the
thousands, ten-thousands, and hundred-thousands places of Hyper-V's
micro. The repacked micro is derived from the digits in the ones, tens,

In [1], changes were made to remove the existing auto-alignment
for pSeries NVDIMM devices. That design promotes strange situations
where the NVDIMM size reported in the domain XML is different
from what QEMU is actually using. We removed the auto-alignment
and relied on standard size validation.
However, this goes against Libvirt design philosophy of not
tampering with existing guest behavior, as pointed out by Daniel
in [2]. Since we can't know for sure whether there are guests that
are relying on the auto-alignment feature to work, the changes
made in [1] are a direct violation of this rule.

There was one attempt a year ago done by me to drop HAL [1] but it was
never resolved. There was another time when Dan suggested to drop HAL
driver [2] but it was decided to keep it around in case device
assignment will be implemented for FreeBSD and the fact that
virt-manager uses node device driver [3].
I checked git history and code and it doesn't look like bhyve supports
device assignment so from that POV it should not block removing HAL.
The argument about virt-manager is not strong as well because libvirt
installed from FreeBSD packages doesn't have HAL support so it will not
affect these users as well [4].
The only users affected by this change would be the ones compiling
libvirt from GIT on FreeBSD.
I looked into alternatives and there is libudev-devd package on FreeBSD
but unfortunately it doesn't work as it doesn't list any devices when
used with libvirt. It provides libudev APIs using devd.
I also looked into devd directly and it provides some APIs but there are
no APIs for device monitoring and events so that would have to be
somehow done by libvirt.
Main motivation for dropping HAL support is to replace libdbus with GLib
dbus implementation and it cannot be done with HAL driver present in
libvirt because HAL APIs heavily depends on symbols provided by libdbus.

Local socket connections were outright disabled because there was no "server"
part in the URI. However, given how requirements and usage scenarios are
evolving, some management apps might need the source libvirt daemon to connect
to the destination daemon over a UNIX socket for peer2peer migration. Since we
cannot know where the socket leads (whether the same daemon or not) let's decide
that based on whether the socket path is non-standard, or rather explicitly
specified in the URI. Checking non-standard path would require to ask the
daemon for configuration and the only misuse that it would prevent would be a
pretty weird one. And that's not worth it. The assumption is that whenever
someone uses explicit UNIX socket paths in the URI for migration they better
know what they are doing.

This change models Xen's permissive setting by adding a writeFiltering

is set to 'no', the Xen permissive setting will be enabled and guests
will be able to write any values into the device's configuration space.
The permissive setting remains disabled in the absense of the

Xen supports passing arbitrary arguments to the QEMU device model via
the 'extra' member of the public libxl_domain_build_info structure.
This patch adds a 'xen' namespace extension, similar to the QEMU and
bhyve drivers, to map arbitrary arguments to the 'extra' member. Only
passthrough of arguments is supported. Passthrough of environment
variables or capabilities adjustments is not supported.

Introduce a new device element "<audio>" which allows

element to specific audio backend.
Example:
<sound model='ich7'>
<audio id='1'/>
</sound>
<audio id='1' type='oss'>
<input dev='/dev/dsp0'/>
<output dev='/dev/dsp0'/>
</audio>
This block maps to OSS audio backend on the host using
/dev/dsp0 device for both input (recording)
and output (playback).
OSS is the only backend supported so far.

Changes:
- Update the descriptions of --current & --config flags.
For --config, the reason to rephrase "next boot" to "next start"
is: "Next boot may still imply somebody selecting "reboot" in the
guest OS and fully expecting the changes to be applied." (per Peter
Krempa)
For --current, existing documentation says:
"If *--current* is specified, affect the current guest state."
It's not entirely clear what states can "current" mean or imply. So
rephrase it in context of the other two related flags --live and
--config.
- While at it, I also took the liberty to replace the few occurrences
of "peristent domain[s]" with "persistent guest[s]"
Fix all occurrences (i.e. as many as I could spot) of this.

Role(master or peer) controls how the domain behaves on migration.
For more details about migration with ivshmem, see
https://git.qemu.org/?p=qemu.git;a=blob_plain;f=docs/system/ivshmem.rst;hb=HEAD
It's a optional attribute in libvirt, and qemu will choose default
role for ivshmem device if the user is not specified.
With device property 'role', the value can be 'master' or 'peer'.
- 'master' (means 'master=on' in qemu), the guest will copy
the shared memory on migration to the destination host.
- 'peer' (means 'master=off' in qemu), the migration is disabled.
