ppc64Compute() is used only once, by virCPUppc64Compare(), which
doesn't use the 'guest' parameter. It was last used by an API
called 'cpuGuestData' that was dropped by commit 03fa904c0c.
Removing the 'guest' parameter will not only remove unused code from
ppc64Compute() but also remove the ppc64MakeCPUData() entirely.

Originally the default encryption engine is populated in the disk
post-parse callback code. This works for disks but for any additional
images introduced either via the block copy API or via the backup API we
don't populate the default.
In case when the backup or block copy is requested on an encrypted image
this would then lead to an error:
error: internal error: Unexpected enum value 0 for virStorageEncryptionEngine
This patch adds another point where we populate the default which is
when setting up a virStorageSource for actual usage.
We keep the original setting in the post-parse callback as that's the
only point that is recorded in the XML file after definition.

Add a test case where 'ramfb' is explicitly disabled for a mediated

Reviewed-by: Ján Tomko <jtomko@redhat.com>
Before commit 73c352ab8c which converted the hostdev commandline
formatter to JSON the 'ramfb' property was formatted only if it was
enabled.
The main reason for that is that enabling 'ramfb' switches the device
model to 'vfio-pci-nohotplug' which actually has the property, while
'vfio-pci' (used when 'ramfb' is disabled or absent) doesn't have it.
Restore the logic to format 'ramfb' only when it's enabled and add a
comment that it's deliberate.

x86Compute() is a static function called only by virCPUx86Compare()
which passes NULL to the 'guest' parameter of x86Compute().
The last caller of x86Compute() that used it with 'guest' != NULL
was an API called 'cpuGuestData'. This API was dropped by commit
03fa904c0c a few years ago. Since then all callers of x86Compute()
uses it with 'guest' = NULL.
Removing the 'guest' parameter allow us to remove a good chunk of
logic that isn't being used for awhile.

There is no guarantee that QEMU and libvirt have been configured
with the same prefix.
In particular, Homebrew on macOS will pass a different, private
prefix for each package version and then use symlinks to make
the files for a specific version appear in the usual locations.
This works perfectly fine as long as one package doesn't try to
go poking around another package's data - which is exactly what
libvirt needs to do in order to read and parse the QEMU interop
data.
qemu_datadir can now be explicitly provided to make this and
other uncommon scenarios work. The common scenario, where QEMU
and libvirt both use the same prefix, is unaffected.

Commit 65b0b746b5 changed spice tests to use latest caps. Before this
change, "FLAG_REAL_CAPS" wasn't being set in testQemuInfoInitArgs(). The
absence of this flag triggered the code path inside
testCompareXMLToArgv() that executed testUpdateQEMUCaps(). This function
will update the host CPU via virQEMUCapsUpdateHostCPUModel() into
virQEMUCapsInitHostCPUModel(). In this function,
virQEMUCapsInitCPUModel() would end up updating the hostCPU inside the
qemuCaps (via virQEMUCapsProbeHostCPU()). Before the forementioned
commit, the host CPU was being defaulted to x86_64, vendor Intel, for
the 'graphics-spice-timeout' test that is using the 'pc' machine type
and 'accel=kvm'.
Today, "FLAG_REAL_CAPS" is being set because we're using the latest caps
from x86_64. This means that the whole code path mentioned above is
skipped. qemuCaps are now being loaded via virQEMUCapsLoadCache()
directly. Without the handling being done by testUpdateQEMUCaps(), the
host CPU is being retrieved later on, down below
qemuProcessCreatePretendCmdPrepare() into qemuProcessUpdateGuestCPU().
The latter will attempt to update the domain cpu and executing a
virCPUCompare with the hostCPU and def->cpu.
All this logic ended up causing a failure of the
'graphics-spice-timeout' test in ppc64 and s390x hosts. This test is
being run with KVM acceleration, and the KVM driver for ppc64 and s390x
will return a default x86_64 CPU with vendor "AMD", making
virCPUCompare() fail with the following message:
"QEMU XML-2-ARGV graphics-spice-timeout.x86_64-latest ... libvirt: CPU
Driver error : the CPU is incompatible with host CPU: host CPU vendor does
not match required CPU vendor Intel"
Fix this test by setting cpu check='none' and avoid the virCPUCompare()
that causes the problem for ppc64 and s390x hosts.
Note that this is a build fix. A more adequate fix would be to mock the
getHost() interface of the cpuDriverX86 for non-x86 hosts, allowing
'fullCPU' to be retrieved in qemuProcessUpdateGuestCPU(), and a proper
x86 CPU to be retrieved in the scenario described above.
