We already use templating to generate sockets, which are all
based off libvirtd's. Push the idea further, and extend it to
cover services as well.
This is more challenging, as the various modular daemons each have
their own needs in terms of what system services needs to be
available before they can be started, which other components of
libvirt they depend on, and so on.
In order to make this sort of per-service tweaks possible, we
introduce a Python script that can merge two systemd units
together. The script is aware of the semantics of systemd's unit
definition format, so it can intelligently merge sections
together.
This generic systemd unit merging mechanism will also supersede
the extremely ad-hoc @deps@ variable, which is currently used in
a single scenario.

For most services, the socket paths can be derived trivially from
the name of the daemon: for virtqemud, for example, they will be
/run/libvirt/virtqemud-sock
/run/libvirt/virtqemud-sock-ro
/run/libvirt/virtqemud-admin-sock
libvirtd and virtproxyd are the exceptions, since their socket
paths will be
/run/libvirt/libvirt-sock
/run/libvirt/libvirt-sock-ro
/run/libvirt/libvirt-admin-sock
So we still need to be able to provide a custom @sockprefix@ in
those cases, but in the most common scenario we can do away with
the requirement by introducing a sensible default.

Commit 93af79fb removed a cleanup label in favor of returning error
values directly in certain cases. But the final return value was changed
from -1 to 0. If we get to the end of the function, that means that
we've waited for the process to exit but it still exists. So we should
return -1. The error message was still being set correctly, but we were

As of v9.4.0-rc2~5 it is possible to specify guest address where
a virtio-mem/virtio-pmem memory device is mapped to. What that
commit forgot to introduce was a check for overlaps.
And yes, this is technically an O(n^2) algorithm, as
virDomainMemoryDefValidate() is called over each memory device
and after this, virDomainMemoryDefValidate() also iterates over
each memory device. But given there's usually only a handful of
such devices, and this runs only when parsing domain XML I guess
code readability wins over some less obvious solution.

Inside of virDomainMemoryDefValidate() there's a check that
address where a virtio-mem memory device is mapped to is a
multiple of its block size. But this check is off by a couple of
bits, because the memory address is in bytes while the block size
is in kibibytes. Therefore, when checking whether address is a
multiple of the block size, the latter has to be multiplied by a
factor of 1024.

The current message can be misleading, because it seems to suggest
that no firmware of the requested type is available on the system.
What actually happens most of the time, however, is that despite
having multiple firmwares of the right type to choose from, none
of them is suitable because of lacking some specific feature or
being incompatible with some setting that the user has explicitly
enabled.
Providing an error message that describes exactly the problem is
not feasible, since we would have to list each candidate along
with the reason why we rejected it, which would get out of hand
quickly.
As a small but hopefully helpful improvement over the current
situation, reword the error message to make it clearer that the
culprit is not necessarily the firmware type, but rather the
overall domain configuration.
