There are two functions declared in qemu_capspriv.h:
1) virQEMUCapsInitHostCPUModel() which is not used anywhere but
qemu_capabilities.c,
2) virQEMUCapsSetSEVCapabilities() which is my personal favorite
but despite that it's never implemented nor called.
Drop them.

We already allow users to provide TFTP root path in network XML
and not specify any DHCP. This makes sense, because dnsmasq is
not only DHCP server but also TFTP server and users might have
a DHCP server configured on their own, outside of libvirt's
control and want just the TFTP part.
By moving TFTP config generator out of DHCP generator and calling
it for every IPv4 range, users can finally enable just TFTP.

Generating configuration file for dnsmasq is done in

In networkDnsmasqConfContents() there's a for() loop which
initializes some variables in its initialization block. This
makes both the loop() statement and variable declaration block
look needlessly ugly. Speaking of variable declaration, also move
some variables which are used only within blocks into their
respective blocks.

The virDomainObj struct has @pid member where the domain's
hypervisor PID is stored (e.g. QEMU/bhyve/libvirt_lxc/... PID).
However, we are not consistent when it comes to shutoff state.
Initially, because virDomainObjNew() uses g_new0() the @pid is
initialized to 0. But when domain is shut off, some functions set
it to -1 (virBhyveProcessStop, virCHProcessStop, qemuProcessStop,
..).
In other places, the @pid is tested to be 0, on some other places
it's tested for being negative and in the rest for being
positive.
To solve this inconsistency we can stick with either value, -1 or
0. I've chosen the latter as it's safer IMO. For instance if by
mistake we'd kill(vm->pid, SIGTERM) we would kill ourselves
instead of init's process group.

In qemu_extdevice.c lives code that handles helper daemons that
are required for some types of devices (e.g. virtiofsd,
vhost-user-gpu, swtpm, etc.). These devices have their own
handling code in separate files, with only a very basic functions
exposed (e.g. for starting/stopping helper process, placing it
into given CGroup, etc.). And these functions all work over a
single instance of device (virDomainVideoDef *, virDomainFSDef *,
etc.), except for TPM handling code which takes virDomainDef *
and iterates over it inside its module.
Remove this oddness and make qemuExtTPM*() functions look closer
to the rest of the code.

We have our own implementation of setns() which was introduced in
v1.2.9-rc1~190 and extended afterwards. The reason was that back
in 2014 we were dealing with glibc that in some of its older
versions did not provide the function. Mostly for non-intel
arches. Nevertheless, glibc now offers the function for all
architectures we care about (aarch64 being the freshest
architecture where the function was introduced, in glibc-2.17).

When a SIGHUP is received a thread is spawned that runs
virStateReload(). However, if SIGINT is received while the former
thread is still running then we may get into problematic
situation: the cleanup code in main() sees drivers initialized
and thus calls virStateCleanup(). So now we have two threads, one
running virStateReload() the other virStateCleanup(). In this
situation it's very likely that a race condition occurs and
either of threads causes SIGSEGV.
To fix this, unmark drivers as initialized in the
virStateReload() thread for the time the function runs.
