The systemd-machined tools libvirt uses were split into a
systemd-container RPM. Without depending on this, libvirt
may silently fallback to the non-systemd cgroup impl which
is not desirable.

IPv6 RA always contains an implicit default route via
the link-local address of the source of RA. This forces
the guest to install a route via isolated network, which
may disturb the guest's networking in case of multiple interfaces.
More info in 013427e6e7.
The validity of this route is controlled by "default [route] lifetime"
field of RA. If the lifetime is set to 0 seconds, then no route
is installed by receiver.
dnsmasq 2.67+ supports "ra-param=<interface>,<RA interval>,<default
lifetime>" option. We pass "ra-param=*,0,0"
(here, RA_interval=0 means default) to disable default gateway in RA
for isolated networks.

At least with systemd v210, NOTIFY_SOCKET is abstact, e.g.
@/org/freedesktop/systemd1/notify. sendmsg() fails on such a socket
with "Connection refused". The unix(7) man page contains the following
details wrt abstract socket addresses
abstract: an abstract socket address is distinguished (from a
pathname socket) by the fact that sun_path[0] is a null byte
('\0'). The socket's address in this namespace is given by the
additional bytes in sun_path that are covered by the specified
length of the address structure. (Null bytes in the name have
no special significance.)
So we need to be more precise about the address length, setting it to
the sizeof sa_family_t + length of address copied to sun_path instead
of setting it to the sizeof the entire sockaddr_un struct.

When fetching domains with virConnectListAllDomains() and when filtering
by snapshot existence is requested the ESX driver first lists all the
domains and then check one-by-one for snapshot existence. This process
takes unnecessarily long time.
To significantly improve the time necessary to finish the query we can
request the snapshot related info directly when querying the list of
domains from VMware.

The old 32-bit-only mingw project had a mismatch in its <sys/types.h>
that omitted ssize_t, but where size_t was a different rank than
int as picked by gnulib. But now that mingw64 (both 32- and 64-bit)
is the more popular platform (Fedora has dropped mingw in favor of
mingw64), we no longer need to carry a hack to gnulib to cater to
the old mingw. This reverts part of commit 1012dc2933.

Commit c9c03ea stopped creating an intermediate file during syntax-check
to save on execution time. It also switched to outputting the whole
incorrectly wrapped file instead of a diff needed to fix it.
Feed the newly wrapped file to diff via a pipe.
Note that fixing it by running test-wrap-argv.pl --in-place or
the unit test with VIR_TEST_REGENERATE_OUTPUT is easier.
Commit 843a70a changed test-wrap-argv.pl to use
/usr/bin/env perl
instead of
/usr/bin/perl
However when called from qemuxml2argvtest with
VIR_TEST_REGENERATE_OUTPUT, PATH is set to '/bin'.
Find the path to perl early in virTestMain, in case we
are going to need it later after we've overridden PATH.
In commit ec5dcf2a and b0b4a35c we have moved qemuhotplugtest's XMLs to

If the config file does not end with a \n, the parser will append
one. When re-allocating the array though, it is mistakenly assuming
that 'len' is the length including the trailing NUL, but it does
not. So we must add 2 to len, when reallocating, not 1.

The virconftest is different from all our other tests in that
the C program only tests a single in/out config file pair. It
relies on a shell wrapper to invoke it once for each test
file.
This gets rid of the shell wrapper and makes the C program
actually run over each test file using the normal test pattern.

In the mock, we have a stub for virNetDevTapCreate(). However,
the mocked version does not exactly as it's native counterpart.
The function receives a string, which is an interface name that
caller would like to have, but it's not guaranteed that they will
get just that one. If they don't, the function free()-s the one
passed and returns the new one. Just like the mocked version. But
what is the mocked version missing is the free().

This one's a bit more complicated. In qemuProcessPrepareDomain()
a master key for encrypting secret for ciphered disks is created.
This object lives within qemuDomainObjPrivate object. It is freed
in qemuProcessStop(), but if nobody calls it (for instance like
our qemuxml2argvtest does), the key object leaks.

Setting up cgroups and other things for all kinds of threads (the
emulator thread, vCPU threads, I/O threads) was copy-pasted every time
new thing was added. Over time each one of those functions changed a
bit differently. So create one function that does all that setup and
start using it, starting with I/O thread setup. That will shave some
duplicated code and maybe fix some bugs as well.
