QEMU commit 3984890 introduced the "pci-hole64-size" property,
to i440FX-pcihost and q35-pcihost with a default setting of 2 GB.
Translate <pcihole64>x<pcihole64/> to:
-global q35-pcihost.pci-hole64-size=x for q35 machines and
-global i440FX-pcihost.pci-hole64-size=x for i440FX-based machines.
Error out on other machine types or if the size was specified
but the pcihost device lacks 'pci-hole64-size' property.

<controller type='pci' index='0' model='pci-root'>
<pcihole64 unit='KiB'>1048576</pcihole64>
</controller>
It can be used to adjust (or disable) the size of the 64-bit
PCI hole. The size attribute is in kilobytes (different unit
can be specified on input), but it gets rounded up to
the nearest GB by QEMU.
Disabling it will be needed for guests that crash with the
64-bit PCI hole (like Windows XP), see:

Extend the probing for qemu-img command line options to check
if -o compat is supported. If the volume definition specifies
the qcow2 format but no compat level and -o compat is supported,
specify -o compat=0.10 to create a QCOW2v2 image.

Re-arrange the code so that the returned bitmap is always initialized to
NULL even on early failures and return an error message as some callers
are already expecting it. Fix up the rest not to shadow the error.
Only compile securityselinuxhelper.c if xattr support was detected to
avoid this error:
securityselinuxhelper.c:34:24: fatal error: attr/xattr.h: No such file
or directory compilation terminated.
Since all SELinux tests depend upon the securityselinuxhelper library,
these test programs are now only build when xattr support is
available.
In commit f905cc9984 a use of
uninitialized data was fixed based on a coverity report. It
turns out it was possible to trigger this issue by pointing
libvirt at non-existent certificate files, typically causing
a crash.
This adds a test case for that scenario. With the above
commit reverted, this new test case will crash with a SEGV.
With the fix applied, it passes, reporting a normal libvirt
error to the caller.

Commit 904e05a2 (v0.9.9) added a per-<disk> seclabel element with
an attribute relabel='no' in order to try and minimize the
impact of shutdown delays when an NFS server disappears. The idea
was that if a disk is on NFS and can't be labeled in the first
place, there is no need to attempt the (no-op) relabel on domain
shutdown. Unfortunately, the way this was implemented was by
modifying the domain XML so that the optimization would survive
libvirtd restart, but in a way that is indistinguishable from an
explicit user setting. Furthermore, once the setting is turned
on, libvirt avoids attempts at labeling, even for operations like
snapshot or blockcopy where the chain is being extended or pivoted
onto non-NFS, where SELinux labeling is once again possible. As
a result, it was impossible to do a blockcopy to pivot from an
NFS image file onto a local file.
The solution is to separate the semantics of a chain that must
not be labeled (which the user can set even on persistent domains)
vs. the optimization of not attempting a relabel on cleanup (a
live-only annotation), and using only the user's explicit notation
rather than the optimization as the decision on whether to skip
a label attempt in the first place. When upgrading an older
libvirtd to a newer, an NFS volume will still attempt the relabel;
but as the avoidance of a relabel was only an optimization, this
shouldn't cause any problems.
In the ideal future, libvirt will eventually have XML describing
EVERY file in the backing chain, with each file having a separate
<seclabel> element. At that point, libvirt will be able to track
more closely which files need a relabel attempt at shutdown. But
until we reach that point, the single <seclabel> for the entire
<disk> chain is treated as a hint - when a chain has only one
file, then we know it is accurate; but if the chain has more than
one file, we have to attempt relabel in spite of the attribute,
in case part of the chain is local and SELinux mattered for that
portion of the chain.

Coverity reported a memleak in the test added in 7efd5fd1b0. In case
the code will be broken and the code will actually parse a faulty bitmap
the resulting pointer would be leaked. Free it although that shouldn't
ever happen.
Currently the virConnectBaselineCPU API does not expose the CPU features
that are part of the CPU's model. This patch adds a new flag,
VIR_CONNECT_BASELINE_CPU_EXPAND_FEATURES, that causes the API to explicitly
list all features that are part of that model.

Previous patch fixed an issue where, when parsing a bitmap from the
string, the bounds of the bitmap weren't checked. That flaw resulted into
crashes. This test tests that case to avoid it in the future.
This resolves the issue that prompted the filing of
https://bugzilla.redhat.com/show_bug.cgi?id=928638
(although the request there is for something much larger and more
general than this patch).
commit f3868259ca disabled the
forwarding to upstream DNS servers of unresolved DNS requests for
names that had no domain, but were just simple host names (no "."
character anywhere in the name). While this behavior is frowned upon
by DNS root servers (that's why it was changed in libvirt), it is
convenient in some cases, and since dnsmasq can be configured to allow
it, it must not be strictly forbidden.
This patch restores the old behavior, but since it is usually
undesirable, restoring it requires specification of a new option in
the network config. Adding the attribute "forwardPlainNames='yes'" to
the <dns> elemnt does the trick - when that attribute is added to a
network config, any simple hostnames that can't be resolved by the
network's dnsmasq instance will be forwarded to the DNS servers listed
in the host's /etc/resolv.conf for an attempt at resolution (just as
any FQDN would be forwarded).
When that attribute *isn't* specified, unresolved simple names will
*not* be forwarded to the upstream DNS server - this is the default
behavior.
I noticed this yesterday and fixed it in a different way, but ended up
with one more problem. It was probably the way I fixed it combined
with one more filename changed.
Anyway, why I'm saying this is that one more filename should be renamed
in order to avoid a race (which I was unable to reproduce, though).
I checked this is the last file those two tests have in common by going
through the code and the re-checked by this "script":
strace -o session.trace -e open ./virnettlssessiontest
strace -o context.trace -e open ./virnettlscontexttest
sort \
<(sed -n '/^open/s/open("\([^"]*\)",.*$/\1/p' context.trace | sort -u)\
<(sed -n '/^open/s/open("\([^"]*\)",.*$/\1/p' session.trace | sort -u)\
| uniq -d| grep '.pem$'
So it should be enough to make these tests independent of each other.

The logic set up in previous patch for exposing VIR_TEST_EXPENSIVE
to individual tests is as follows:
make check VIR_TEST_EXPENSIVE=0 => getenv("VIR_TEST_EXPENSIVE") sees "0"
make check VIR_TEST_EXPENSIVE=1 => getenv("VIR_TEST_EXPENSIVE") sees "1"
make check => getenv("VIR_TEST_EXPENSIVE") sees
either "0" or "1", based on configure options
cd tests; ./FOOtest => getenv("VIR_TEST_EXPENSIVE") sees
whatever is in your environment (usually NULL, but possibly garbage)
Merely checking if VIR_TEST_EXPENSIVE is set in the environment
does the wrong thing; likewise, it is unsafe to assume the
variable will always contain a valid number.
As such, it helps to have helper functions, instead of making each
expensive test repeat the probe of the environment.

The gnulib testsuite is relatively stable - the only times it is
likely to have a test change from pass to fail is on a gnulib
submodule update or a major system change (such as moving from
Fedora 18 to 19, or other large change to libc). While it is an
important test for end users on arbitrary machines (to make sure
that the portability glue works for their machine), it mostly
wastes time for development testing (as most developers aren't
making any of the major changes that would cause gnulib tests
to alter behavior). Thus, it pays to make the tests optional
at configure time, defaulting to off for development, on for
tarballs, with autobuilders requesting it to be on. It also
helps to allow a make-time override, via VIR_TEST_EXPENSIVE=[01]
(much the way automake sets up V=[01] for overriding the configure
time default of how verbose to be).
Automake has some pretty hard-coded magic with regards to the
TESTS variable; I had quite a job figuring out how to keep
'make distcheck' passing regardless of the configure option
setting in use, while still disabling the tests at runtime
when I did not configure them on and did not use the override
variable. Thankfully, we require GNU make, which lets me
hide some information from Automake's magic handling of TESTS.
