In our meson scripts, we use configure_file(copy:true) to copy
files from srcdir into builddir. However, as of meson-0.64.0,
this is deprecated [1] in favor of using:
fs = import('fs')
fs.copyfile(in, out)
Except, the submodule's new method wasn't introduced until
0.64.0. And since we can't bump the minimal meson version we
require, we have to work with both: new and old versions.
Now, the fun part: fs.copyfile() is not a drop in replacement as
it returns different type (a custom_target object). This is
incompatible with places where we store the configure_file()
retval in a variable to process it further.
While we could just replace 'copy:true' with a dummy
'configuration:...' (say 'configuration: configmake_conf') we
can't do that for binary files (like src/fonts/ or src/images/).
Therefore, places where we are not interested in the retval can
be switched to fs.copyfile() and places where we are interested
in the retval will just use a dummy 'configuration:'.
Except, src/network/meson.build. In here we not just copy the
file but also specify alternative install dir and that's not
something that fs.copyfile() can handle. Yet, using 'copy: true'
is viewed wrong [2].

With cgroupv2 this has better effect on the resource allocation. An
excerpt from Documentation/admin-guide/cgroup-v2.rst explains is this
way:
Migrating a process across cgroups is a relatively expensive operation
and stateful resources such as memory are not moved together with the
process. This is an explicit design decision as there often exist
inherent trade-offs between migration and various hot paths in terms
of synchronization cost.
[...]
Setting a non-empty value to "cpuset.mems" causes memory of
tasks within the cgroup to be migrated to the designated nodes if
they are currently using memory outside of the designated nodes.

When starting QEMU, or when hotplugging a PCI device QEMU might
lock some memory. How much? Well, that's an undecidable problem.
But despite that, we try to guess. And it more or less works,
until there's a counter example. This time, it's a guest with
both <hostdev/> and an NVMe <disk/>. I've started a simple guest
with 4GiB of memory:
# virsh dominfo fedora
Max memory: 4194304 KiB
Used memory: 4194304 KiB
And here are the amounts of memory that QEMU tried to lock,
obtained via:
grep VmLck /proc/$(pgrep qemu-kvm)/status
1) with just one <hostdev/>
VmLck: 4194308 kB
2) with just one NVMe <disk/>
VmLck: 4328544 kB
3) with one <hostdev/> and one NVMe <disk/>
VmLck: 8522852 kB
Now, what's surprising is case 2) where the locked memory exceeds
the VM memory. It almost resembles VDPA. Therefore, treat is as
such.
Unfortunately, I don't have a box with two or more spare NVMe-s
so I can't tell for sure. But setting limit too tight means QEMU
refuses to start.

This is a relic of commit v3.7.0-rc1~132 when getter/setter APIs

Throughout all of our network driver code we assume that
dnsmasqPid of value -1 means the network has no dnsmasq process
running. There are plenty of calls to:
virNetworkObjSetDnsmasqPid(obj, -1);
or:
pid_t dnsmasqPid = virNetworkObjGetDnsmasqPid(obj);
if (dnsmasqPid > 0) ...;
Now, a virNetworkObj is created via virNetworkObjNew() which
might as well set this de-facto default value.

Assume there's a dnsmasq running (because there's an active
virtual network that spawned it). Now, shut down the daemon,
remove the dnsmasq binary and start the daemon again. At this
point, networkUpdateState() is called, but dnsmasq_caps is NULL
(because networkStateInitialize() called earlier failed to set
them, rightfully though).
Now, the networkUpdateState() tries to read the dnsmasq's PID
file using virPidFileReadIfAlive() which takes a path to the
corresponding binary as one of its arguments. To provide that
path, dnsmasqCapsGetBinaryPath() is called, but since
dnsmasq_caps is NULL, it dereferences it and thus causes a crash.
It's true that virPidFileReadIfAlive() can deal with a removed
binary (well virPidFileReadPathIfAlive() which it calls can), but
iff the binary path is provided in its absolute form. Otherwise,
virFileResolveAllLinks() fails to canonicalize the path
(expected, the path doesn't exist anyway).
Therefore, reading dnsmasq's PID file didn't work before
v8.1.0-rc1~401 which introduced this crash. It was always set to
-1. But passing NULL as binary path instead, makes
virPidFileReadIfAlive() return early, right after the PID file is
read and it's confirmed the PID exists.
Yes, this may yield wrong results, as the PID might be of a
completely different binary. But this problem is preexistent and
until we start locking PID files, there's nothing we can do about
it. IOW, it would require rework of dnsmasq PID file handling.
