In the Makefile in tests/ we initialize couple of variables like
test_programs, test_libraries and test_helpers. These variables
contain all the targets that we need to build in order to run
the test suite. So we initialize test_programs and test_helpers
and then conditionally add targets to them depending on what we
are building with. Then we repeat the same process with
test_libraries. It makes no sense to have two separate if-endif
sequences.

This tests uses preload, which should work on any ELF-based platform
(and indeed it passes on Linux, GNU/kFreeBSD, and FreeBSD).
Also remove the WITH_DBUS conditional, as the test is already built
based on that conditional.
Add tests for controller based disks to check disk address compatibility

If the allocation fails in DO_TEST_FLUSH_PROLOGUE, then 'mgr == NULL',
but the code continues on - which won't be good. So modify the macro
to cause an immediate failure and jump to a cleanup label.

If you've ever tried running a huge page backed guest under
different user than in qemu.conf, you probably failed. Problem is
even though we have corresponding APIs in the security drivers,
there's no implementation and thus we don't relabel the huge page
path. But even if we did, so far all of the domains share the
same path:
/hugepageMount/libvirt/qemu
Our only option there would be to set 0777 mode on the qemu dir
which is totally unsafe. Therefore, we can create dir on
per-domain basis, i.e.:
/hugepageMount/libvirt/qemu/domainName
and chown domainName dir to the user that domain is configured to
run under.

Since the great rework of how we store vcpu- and iothread-related
data, we have overly complex part of code that is trying to format the
scheduler tuning data in as less lines as possible by grouping
settings for multiple threads. That was designed as an input syntax
sugar for users, but we don't need to also use that when formatting
the XML. Switching to simple enumeration makes the code nicer,
shorter and more welcoming to future changes.

So far the NSS module looks up only hostnames as provided by
guests themselves. However, there are some cases where this is
not enough: e.g. when there's a fresh new guest being installed
(with some generic hostname) say from a live ISO image; or some
(older) systems don't advertise their hostname in DHCP
transactions at all.
In cases like that it would be helpful if we translate domain
name as seen by libvirt too so that users can:
# virsh start $dom && ssh $dom
In order to achieve that new libvirt-guest module is introduced,
while older libvirt module maintains its current behaviour (that
is translating guest provided names into IP addresses).

The name of the exported functions for an NSS module is quite
fixed, it is derived from the module name:

Since we will create another NSS module with very similar

Problem with VIR_FREE() is that we are not linking
libvirt-utils.so to our mock libs therefore there will be an
unresolved symbol. Fortunately, nsstest that eventually links
with the nssmock links also with libvirt-utils.so and thus the
symbol is resolved after all. However, if one wants to run the
test binary under valgrind it is impossible to do so. Because of
the unresolved symbol.

If libvirtd is running unprivileged, it can open a device's PCI config
data in sysfs, but can only read the first 64 bytes. But as part of
determining whether a device is Express or legacy PCI,
qemuDomainDeviceCalculatePCIConnectFlags() will be updated in a future
patch to call virPCIDeviceIsPCIExpress(), which tries to read beyond
the first 64 bytes of the PCI config data and fails with an error log
if the read is unsuccessful.
In order to avoid creating a parallel "quiet" version of
virPCIDeviceIsPCIExpress(), this patch passes a virQEMUDriverPtr down
through all the call chains that initialize the
qemuDomainFillDevicePCIConnectFlagsIterData, and saves the driver
pointer with the rest of the iterdata so that it can be used by
qemuDomainDeviceCalculatePCIConnectFlags(). This pointer isn't used
yet, but will be used in an upcoming patch (that detects Express vs
legacy PCI for VFIO assigned devices) to examine driver->privileged.
QEMU 2.8.0 adds support for unavailable-features in
query-cpu-definitions reply. The unavailable-features array lists CPU
features which prevent a corresponding CPU model from being usable on
current host. It can only be used when all the unavailable features are
disabled. Empty array means the CPU model can be used without
modifications.
We can use unavailable-features for providing CPU model usability info
in domain capabilities XML:
<domainCapabilities>

<mode name='host-passthrough' supported='yes'/>
<mode name='host-model' supported='yes'>
<model fallback='allow'>Skylake-Client</model>

"host" CPU model is supported by a special host-passthrough CPU mode and
users is not allowed to specify this model directly with custom mode.
Thus we should not advertise "host" CPU model in domain capabilities.
This worked well on architectures for which libvirt provides a list of
supported CPU models in cpu_map.xml (since "host" is not in the list).
But we need to explicitly filter "host" model out for all other
architectures.
