Querying "host" CPU model expansion only makes sense for KVM. QEMU 2.9.0
introduces a new "max" CPU model which can be used to ask QEMU what the
best CPU it can provide to a TCG domain is.

While query-cpu-model-expansion returns only boolean features on s390,
but x86_64 reports some integer and string properties which we are

While reviewing a patch from Andrea that modified this test case, I
realized that although it was "properly failing" (it's a negative
test), that it was failing for the wrong reason (the MULTIFUNCTION cap
wasn't set in the test case, so it was saying that multifunction=on
wasn't supported by the QEMU binary; instead it should have been
complaining that it had run out of PCI slots of the appropriate type
and couldn't automatically add any more).
This improper failure had started when I added the patch to
automatically aggregate pcie-root-ports onto multiple functions of
each pcie-root slot, but I hadn't noticed it because the test still
failed.
This patch corrects the test case to 1) set the MULTIFUNCTION flag in
the caps, and 2) attempt to add 241 pcie-root-ports to a domain. Since
there are 30 slots available on a pcie-root (slot 0 is reserved, and
slot 31 is used by the integrated SATA controller), and a
pcie-root-port can only be placed on a function of a slot on
pcie-root, the maximum number of pcie-root-ports in any domain is 240.
virQEMUCapsHasPCIMultiBus() performs a version check on
the QEMU binary to figure out whether multiple buses are
supported, so to get the correct aliases assigned when
dealing with pSeries guests we need to spoof the version
accordingly in the test suite.
Due to the extra architecture-specific logic, it's already
necessary for users to call virQEMUCapsHasPCIMultiBus(),
so the capability itself is just a pointless distraction.
While "x86" is a CPU sub driver name, it is not a recognized name of any
architecture known to libvirt. Let's use "x86_64" prefix which can be
used with virArch APIs.

Our documentation of the domain capabilities XML says that the fallback
attribute of a CPU model is used to indicate whether the CPU model was
detected by libvirt itself (fallback="allow") or by asking the
hypervisor (fallback="forbid"). We need to properly set
fallback="forbid" when CPU model comes from QEMU to match the
documentation.

Now that QEMU_CAPS_DEVICE_PCI_BRIDGE is no longer checked
unless a pci-bridge is really part of the configuration,
and most uses of the legacy PCI controller combo have been
dropped from tests that use PCIe machine types, we can
drop the corresponding capabilities from a lot of test
cases.
Up until a while ago, libvirt would automatically add a legacy
PCI controllers combo (dmi-to-pci-bridge + pci-bridge) to any
PCIe machine type (x86_64/q35 and aarch64/virt).
As a result, a number of input and output files in the test
suite ended up containing the legacy PCI controllers, even
though they are not needed or in any way relevant to the
feature being tested.
Get rid of most of the occurrences. Most of the time, this
just means removing the controllers from the input file and
regenerating the output files; in a few instances, some
minor tweaking is performed on the input file, most notably
removing the memory balloon: as memory balloon support was
not the scope of the test being changed, there is no loss
of test coverage from doing so.
Several occurrences of the legacy PCI controllers remain in
the test suite, both because removing their usage would have
required even more tweaking, and because we still want to
have coverage of this perfectly valid combination.
The 'raw' block driver in Qemu is not directly interesting from
libvirt's perspective, but it can be layered above some other block
drivers and this may be interesting for the user.
The patch adds support for the 'raw' block driver. The driver is treated
simply as a pass-through and child driver in JSON is queried to get the
necessary information.

Add a new storage driver registration function that will force the
backend code to fail if any of the storage backend modules can't be
loaded. This will make sure that they work and are present.
If driver modules are enabled turn storage driver backends into
dynamically loadable objects. This will allow greater modularity for
binary distributions, where heavyweight dependencies as rbd and gluster
can be avoided by selecting only a subset of drivers if the rest is not
necessary.
The storage modules are installed into 'LIBDIR/libvirt/storage-backend/'
and users can override the location by using
'LIBVIRT_STORAGE_BACKEND_DIR' environment variable.
rpm based distros will at this point install all the backends when
libvirt-daemon-driver-storage package is installed.
Add APIs that allow to dynamically register driver backends so that the
list of available drivers does not need to be known during compile time.
This will allow us to modularize the storage driver on runtime.
Pass the registration function name to virDriverLoadModule so that we
can later call specific functions if necessary (e.g. for testing
purposes). This gets rid of the rather ugly automatic name generator and
unifies the code to load/initialize the modules.
It's also clear which registration function gets called.
QEMU 2.9.0 is not released yet but it's close to its release and
we need this data to implement new features that will be in
that release.

Add a test that allows providing the parent fabric_wwn in the input XML
in order to create the vHBA.
This also fixes a mixed setting of the fabric_wwn field from the read
test driver XML strings.
Add a test that will mimic creation and destruction of a vHBA
by using node device XML. The design will allow for testing the
multiple mechanisms.
The first test uses just <parent> in the node device XML. This is
somewhat similar to the existing objecteventtest, except that this
test will not provide input wwnn/wwpn's (similar to how the process
is described for the the libvirt wiki).
This requires mocking the virRandomGenerateWWN since parsing the
input XML (virNodeDevCapSCSIHostParseXML) requires either a provided
wwnn/wwpn in the XML or the ability to randomly generate the wwnn/wwpn.
Create a virscsihost.c and place the functions there. That removes the
last #ifdef __linux__ from virutil.c.
Take the opporunity to also change the function names and in one case
the parameters slightly
Rather than have them mixed in with the virutil apis, create a separate
virvhba.c module and move the vHBA related calls into there. Soon there
will be more added.
Also modify the names of the functions and some arguments to be more
indicative of what is really happening. Adjust the callers respectively.
While I was changing fchosttest, rather than the non-descriptive names
test1...test6, rename them to match what the test is doing.
Commit id '666bee3' made fabric_name optional; however, if fabric name
was present, then a leak would occur.

Alter "test-scsi-host-vport" to be "scsi_host1" to match the real
environment. This is the vport capable HBA - IOW the NPIV device.
Add more fields to scsi_host1 as well.
Alter the XML being used by the objecttest to create a vHBA in order
to match the scsi_host1 parent name and to use validateable wwnn/wwpn.
This will allow for realistic testing.

To make sure bit 'b' fits into the bitmap, we need to allocate b+1
bits, since we number from 0.
Adjust the bitmap test to set a bit at a multiple of 16.
That way the test fails without this fix, because the VIR_REALLOC
call clears the newly added memory even if the original pointer
has not changed.
Due to a logic error, the autofilling of USB port when a bus is
specified:
<address type='usb' bus='0'/>
does not work for non-hub devices on domain startup.
Fix the logic in qemuDomainAssignUSBPortsIterator to also
assign ports for USB addresses that do not yet have one.

Recently e1000 NIC support was added to bhyve; implement that in
the bhyve driver:
- Add capability check by analyzing output of the 'bhyve -s 0,e1000'
command
- Modify bhyveBuildNetArgStr() to support e1000 and also pass
virConnectPtr so it could call bhyveDriverGetCaps() to check if this
NIC is supported
- Modify command parsing code to add support for e1000 and adjust tests
- Add net-e1000 test
