The 'newapi.xsl' stylesheet was referencing non-existing paths to the
XML files holding ACL permission flags for individual APIs. Additionally
the 'document()' XSL function doesn't even allow concatenation of the
path as it was done via '{$builddir}/src..', but requires either direct
argument or use of the 'concat()' function.
This meant that the 'acls' variable was always empty and thus none of
our API documentation was actually generated with the 'acl' section.
Fix it by passing the path to the XML via an argument to the stylesheet
as the files differ based on which document is being generated.
Since the 'admin' API does not have ACL we need to handle it separately

This implements XML config to represent a subset of the features
supported by 'passt' (https://passt.top), which is an alternative
backend for emulated network devices that requires no elevated
privileges (similar to slirp, but "better").
Along with setting the backend to use passt (via <backend
type='passt'/> when the interface type='user'), we also support
passt's --log-file and --interface options (via the <backend>
subelement logFile and upstream attributes) and its --tcp-ports and
--udp-ports options (which selectively forward incoming connections to
the host on to the guest) via the new <portForward> subelement of
<interface>. Here is an example of the config for a network interface
that uses passt to connect:
<interface type='user'>
<mac address='52:54:00:a8:33:fc'/>
<ip address='192.168.221.122' family='ipv4'/>
<model type='virtio'/>
<backend type='passt' logFile='/tmp/xyzzy.log' upstream='eth0'/>
<portForward address='10.0.0.1' proto='tcp' dev='eth0'>
<range start='2022' to='22'/>
<range start='5000' end='5099' to='1000'/>
<range start='5010' end='5029' exclude='yes'/>
</portForward>
<portForward proto='udp'>
<range start='10101'/>
</portForward>
</interface>
In this case:
* the guest will be offered address 192.168.221.122 for its interface
via DHCP
* the passt process will write all log messages to /tmp/xyzzy.log
* routes to the outside for the guest will be derived from the
addresses and routes associated with the host interface "eth0".
* incoming tcp port 2022 to the host will be forwarded to port 22
on the guest.
* incoming tcp ports 5000-5099 (with the exception of ports 5010-5029)
to the host will be forwarded to port 1000-1099 on the guest.
* incoming udp packets on port 10101 will be forwarded (unchanged) to
the guest.

the following disclaimer:
Note: runtime-collected statistics and their names fall outside QEMU's usual
deprecation policies. QEMU will try to keep the set of available data
stable, together with their names, but will not guarantee stability
at all costs; the same is true of providers that source statistics
externally, e.g. from Linux. For example, if the same value is being
tracked with different names on different architectures or by different
providers, one of them might be renamed. A statistic might go away if
an algorithm is changed or some code is removed; changing a default
might cause previously useful statistics to always report 0. Such
changes, however, are expected to be rare.
Since libvirt is not doing any form of conversion of the stats we can't
meaningfully document any of the returned fields. At the same time we
can't even meaningfully provide any form of API stability for the field
names.
Modify the documentation for the 'VIR_DOMAIN_STATS_VM' group both in the
API docs and in the virsh man page to reflect that and disclaim any form
of stability guarantees we provide normally.

Due to the setup of the modular daemon service files the reverting to non-socket
activated daemons could have never worked. The reason is that masking the
socket files prevents starting the daemons since they require (as in Requires=
rather than Wants= in the service file) the sockets. On top of that it creates
issues with some libvirt-guests setups and needlessly increases our support
matrix.
Nothing prevents users to modify their setup in a way that will still work
without socket activation, but supporting such setup only creates burden on our
part.
This technically reverts most of commit 59d30adacd except the change made to
the libvirtd manpage since the monolithic daemon still supports traditional mode
of starting even on systemd.

Libvirt provides QMP passthrough APIs for the QEMU driver and these are
exposed in virsh. It is not especially pleasant, however, using the raw
QMP JSON syntax. QEMU has a tool 'qmp-shell' which can speak QMP and
exposes a human friendly interactive shell. It is not possible to use
this with libvirt managed guest, however, since only one client can
attach to the QMP socket at any point in time. While it would be
possible to configure a second QMP socket for a VM, it may not be
an known requirement at the time the guest is provisioned.
The virt-qmp-proxy tool aims to solve this problem. It opens a UNIX
socket and listens for incoming client connections, speaking QMP on
the connected socket. It will forward any QMP commands received onto
the running libvirt QEMU guest, and forward any replies back to the
QMP client. It will also forward back events.
$ virsh start demo
$ virt-qmp-proxy demo demo.qmp &
$ qmp-shell demo.qmp
Welcome to the QMP low-level shell!
Connected to QEMU 6.2.0
(QEMU) query-kvm
{
"return": {
"enabled": true,
"present": true
}
}
Note this tool of course has the same risks as the raw libvirt
QMP passthrough. It is safe to run query commands to fetch information
but commands which change the QEMU state risk disrupting libvirt's
management of QEMU, potentially resulting in data loss/corruption in
the worst case. Any use of this tool will cause the guest to be marked
as tainted as an warning that it could be in an unexpected state.
Since this tool introduces a python dependency it is not desirable
to include it in any of the existing RPMs in libvirt. This tool is
also QEMU specific, so isn't appropriate to bundle with the generic
tools. Thus a new RPM is introduced 'libvirt-clients-qemu', to
contain additional QEMU specific tools, with extra external deps.

After some debugging and discussion with systemd team it turns out we
are misusing the ordering in libvirt-guests.service. That happened
because we want to support both monolithic and modular daemon setups and
on top of that we also want to support socket activation and services
without socket activation. Unfortunately this is impossible to express
in the unit file because of how transactions are handled in systemd when
dependencies are resolved and multiple actions (jobs) are queued. For
explanation from Michal Sekletar see comment #7 in the BZ this patch is
fixing:
https://bugzilla.redhat.com/show_bug.cgi?id=1964855#c7
In order to support all the scenarios this patch also amends the
manpages so that users that are changing the default can also read how
to correct the dependency ordering in libvirt-guests unit file.
Ideally we would also keep the existing configuration during upgrade,
but due to our huge support matrix this seems hardly feasible as it
could introduce even more problems.

When reconnecting to a running QEMU process, we construct the
per-domain path in all hugetlbfs mounts. This is a relict from
the past (v3.4.0-100-g5b24d25062) where we switched to a
per-domain path and we want to create those paths when libvirtd
restarts on upgrade.
And with namespaces enabled there is one corner case where the
path is not created. In fact an error is reported and the
reconnect fails. Ideally, all mount events are propagated into
the QEMU's namespace. And they probably are, except when the
target path does not exist inside the namespace. Now, it's pretty
common for users to mount hugetlbfs under /dev (e.g.
/dev/hugepages), but if domain is started without hugepages (or
more specifically - private hugetlbfs path wasn't created on
domain startup), then the reconnect code tries to create it.
But it fails to do so, well, it fails to set seclabels on the
path because, because the path does not exist in the private
namespace. And it doesn't exist because we specifically create
only a subset of all possible /dev nodes. Therefore, the mount
event, whilst propagated, is not successful and hence the
filesystem is not mounted. We have to do it ourselves.
If hugetlbfs is mount anywhere else there's no problem and this
is effectively a dead code.

complication: many distro packages for edk2 include, in addition
to general purpose firmware images, builds that are targeting the
Confidential Computing use case.
For those, the firmware descriptor will not advertise the
enrolled-keys feature, which will technically make them suitable
for satisfying a configuration such as
<os firmware='efi'>
<firmware>
<feature state='off' name='enrolled-keys'/>
</firmware>
</os>
In practice, users will expect the general purpose build to be
