Add test data based on qemu commit v6.0.0-540-g6005ee07c3.
Notable changes are the removal of 'sheepdog' disk storage protocol.
Additionally the cpu model reported when probing seems to have changed
from:
"model-id": "AMD Ryzen 9 3900X 12-Core Processor "
to:
"model-id": "QEMU TCG CPU version 2.5+"
despite building on the same machine. This probably also results in the
2 test changes in the CPU definition which popped up in this update.

QEMU is dropping sheepdog support in 6.1 so we need to limit the test
case to the latest version supporting sheepdog as it won't be described
by the QMP schema any more.

QEMU dropped sheepdog support for the 6.1 release. Since we use schema
validation in the image creation it would create test failures.
In this instance we just drop the test altogether as adding versioned
capabilities would be a bit too overkill for this scenario.

For the real-capabilities test cases testing 'latest' capabilities we
strip off the alias from 'pc' to the appropriate versioned machine type
to prevent update to all tests when bumping qemu capabilities.
Recenly we also started caching the capabilities to prevent re-parsing
the XML all the time. The commit adding the caching kept the alias
stripping prior to cache insertion, thus the cache contains the stripped
alias.
This leads to problem when a test case is added where the 'latest'
equals to the selected version.
Move the machine alias stripping after we create a local copy thus
stripping it only for 'latest' tests.

Since Xen 4.5 libxl allows to set affinities during domain creation.
This enables Xen to allocate the domain memory on NUMA systems close to
the specified pcpus.
Libvirt can now handle <domain/cputune/vcpupin> in domU.xml correctly.
Without this change, Xen will create the domU and assign NUMA memory and
vcpu affinities on its own. Later libvirt will adjust the affinity,
which may move the vcpus away from the assigned NUMA node.

The aim of this function is to return whether domain definition

The basic use case of VIR_IDENTITY_AUTORESTORE() is in
conjunction with virIdentityElevateCurrent(). What happens is
that virIdentityElevateCurrent() gets current identity (which
increases the refcounter of thread local virIdentity object) and
returns a pointer to it. Later, when the variable goes out of
scope the virIdentityRestoreHelper() is called which calls
virIdentitySetCurrent() over the old identity. But this means
that the refcounter is increased again.
Therefore, we have to explicitly decrease the refcounter by
calling g_object_unref().

The original virNumaGetNodeCPUs() returns an empty virBitmap if
given NUMA node has no CPUs. But that's not how our mock behaves
- it looks under $fakesysfs/node/node$N/cpulist only to find an
empty file which is then passed to virBitmapParseUnlimited()
which threats such input as error.
Fortunately, we don't have any fake sysfs data where this path is

When a test has a wrapper over main() (e.g. because it's
preloading some mock libraries). the main() is renamed to
something else (usually mymain()), and main() is generated by
calling one of VIR_TEST_MAIN() or VIR_TEST_MAIN_PRELOAD() macros.
This has a neat side effect - if mymain() returns an error a
short summary is printed, e.g.:
Some tests failed. Run them using:
VIR_TEST_DEBUG=1 VIR_TEST_RANGE=5-6 ./virtest
However, this detection only works if EXIT_FAILURE is returned by
mymain(). Document and enforce this limitation.

A secret can be marked with the "private" attribute. The intent was that
it is not possible for any libvirt client to be able to read the secret
value, it would only be accesible from within libvirtd. eg the QEMU
driver can read the value to launch a guest.
With the modular daemons, the QEMU, storage and secret drivers are all
running in separate daemons. The QEMU and storage drivers thus appear to
be normal libvirt client's from the POV of the secret driver, and thus
they are not able to read a private secret. This is unhelpful.
With the previous patches that introduced a "system token" to the
identity object, we can now distinguish APIs invoked by libvirt daemons
from those invoked by client applications.

When fetching the value of a private secret, we need to use an elevated
identity otherwise the secret driver will deny access.
When using the modular daemons, the elevated identity needs to be active
before the secret driver connection is opened, and it will apply to all
APIs calls made on that conncetion.
When using the monolithic daemon, the identity at time of opening the
connection is ignored, and the elevated identity needs to be active
precisely at the time the virSecretGetValue API call is made.
After acquiring the secret value, the elevated identity should be
cleared.
This sounds complex, but is fairly straightfoward with the automatic
cleanup callbacks.

The drivers can all call virGetConnectXXX to open a connection to a
secondary driver. For example, when creating a encrypted storage volume,
the storage driver has to open a secret driver connection, or when
starting a guest, the QEMU driver has to open the network driver to
lookup a virtual network.
When using monolithic libvirtd, the connection has the same effective
identity as the client, since everything is still in the same process.
When using the modular daemons, however, the remote daemon sees the
identity of the calling daemon. This is a mistake as it results in
the modular daemons seeing the client with elevated privileges.
We need to pass on the current identity explicitly when opening the
secondary drivers. This is the same thing that is done by daemon RPC
dispatcher code when it is directly forwarding top level API calls
from virtproxyd and other daemons.

When creating the system identity set the system token. The system
token is currently stored in a local path
/var/run/libvirt/common/system.token
Obviously with only traditional UNIX DAC in effect, this is largely
security through obscurity, if the client is running at the same
privilege level as the daemon. It does, however, reliably distinguish
an unprivileged client from the system daemons.
With a MAC system like SELinux though, or possible use of containers,
access can be further restricted.
A possible future improvement for Linux would be to populate the
kernel keyring with a secret for libvirt daemons to share.

We want a way to distinguish between calls from a libvirt daemon, and a
regular client application when both are running as the same user
account. This is not possible with the current set of attributes
recorded against an identity, as there is nothing that is common to all
of the modular libvirt daemons, while distinct to all other processes.
We thus introduce the idea of a system token, which is simply a random
hex string that is only known by the libvirt daemons, to be recorded
against the system identity.
