Long ago we adapted to Linux kernel changes which inverted the
behaviour of the conntrack --ctdir setting:
commit a6a04ea47a
Author: Stefan Berger <stefanb@us.ibm.com>
Date: Wed May 15 21:02:11 2013 -0400
nwfilter: check for inverted ctdir
Linux netfilter at some point (Linux 2.6.39) inverted the meaning of the
'--ctdir reply' and newer netfilter implementations now expect
'--ctdir original' instead and vice-versa.
We check for the kernel version and assume that all Linux kernels with version
2.6.39 have the newer inverted logic.
Any distro backporting the Linux kernel patch that inverts the --ctdir logic
(Linux commit 96120d86f) must also backport this patch for Linux and
adapt the kernel version being tested for.

Given our supported platform targets, we no longer need to
consider a version of Linux before 2.6.39, so can drop
support for the old direction behaviour.
The test suite updates are triggered because that never
probed for the ctdir direction, and so the iptables syntax
generator unconditionally dropped the ctdir args.

The way that vircgroupmock works is that the vircgrouptest
creates a temporary directory and sets LIBVIRT_FAKE_ROOT_DIR env
variable which is then checked by the mock at the beginning of
basically every function it overrides (access(), stat in all its
flavours, mkdir(), etc.). The mock then creates a CGroup dir
structure. But the test is allowed to change the directory, to
accommodate environment for the particular test case. This is
done by changing the environment variable which is then detected
by the mock and the whole process repeats.
However, the way the mock detect changes is buggy. After it got
the environment variable it compares it to the last known value
(global variable @fakerootdir) and if they don't match the last
known value is set to point to the new value. Problem is that the
result of getenv() is assigned to the @fakerootdir directly.
Therefore, @fakerootdir points somewhere into the buffer of
environment variables. In turn, when the test sets new value (via
g_setenv()) it may be placed at the very same position in the env
var buffer and thus the mock fails to detect the change.
The solution is to keep our private copy of the value (by
g_strdup()) which makes the variable not rely on
getenv()/setenv() placing values at random positions.

Currently the 'nvram_template' entry is mandatory when parsing the
firmware descriptor based on flash. QEMU is extending the firmware
descriptor spec to make the 'nvram_template' optional, depending
on the value of a new 'mode' field:
- "split"
* "executable" contains read-only CODE
* "nvram_template" contains read-write VARS
- "combined"
* "executable" contains read-write CODE and VARs
* "nvram_template" not present
- "stateless"
* "executable" contains read-only CODE and VARs
* "nvram_template" not present
In the latter case, the guest OS can write vars but the
firmware will make no attempt to persist them, so any changes
will be lost at poweroff.
For now we parse this new 'mode' but discard any firmware
which is not 'mode=split' when matching for a domain.
In the tests we have a mixture of files with and without the
mode attribute.

When building the default memory backend (which has id='pc.ram')
and no guest NUMA is configured then
qemuBuildMemCommandLineMemoryDefaultBackend() is called. However,
its return value is ignored which means that on invalid
configuration (e.g. when non-existent hugepage size was
requested) an error is reported into the logs but QEMU is started
anyway. And while QEMU does error out its error message doesn't
give much clue what's going on:
qemu-system-x86_64: Memory backend 'pc.ram' not found
While at it, introduce a test case. While I could chose a nice
looking value (e.g. 4MiB) that's exactly what I wanted to avoid,
because while such value might not be possible on x84_64 it may
be possible on other arches (e.g. ppc is notoriously known for
supporting wide range of HP sizes). Let's stick with obviously
wrong value of 5MiB.
