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 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.

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.

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.

The securityselinuxhelper is a mock that's replacing libselinux
APIs with our own implementation to achieve deterministic
results. Our implementation uses env vars (among other things) to
hold internal state. For instance, "FAKE_SELINUX_CONTEXT" and
"FAKE_SELINUX_DISABLED" variables are used. However, as we were
switching from setenv() to g_setenv() we also changed the set of
possible retvals from setcon_raw() and security_disable().
Previously, the retval of setenv() was used directly which
returns 0 on success and -1 on error. But g_setenv() has
different retval semantics: it returns 1 on success and 0 on
error.
This discrepancy can be observed by running viridentitytest where
case #2 reports an error ("!") - because setcon_raw() returns 1.

the upper limit for the value is UINT_MAX, well UINT_MAX / 1024

The function is used to automatically feed a buffer into a pipe which
can be used by the command to read contents of the buffer.
Rather than passing in a pipe, let's create the pipe inside
virCommandSetSendBuffer and directly associate the reader end with the
command. This way the ownership of both ends of the pipe will end up
with the virCommand right away reducing the need of cleanup in callers.
The returned value then can be used just to format the appropriate
arguments without worrying about cleanup or failure.

The <teaming> element in <interface> allows pairing two interfaces
together as a simple "failover bond" network device in a guest. One of
the devices is the "transient" interface - it will be preferred for
all network traffic when it is present, but may be removed when
necessary, in particular during migration, when traffic will instead
go through the other interface of the pair - the "persistent"
interface. As it happens, in the QEMU implementation of this teaming
pair (called "virtio failover" in QEMU) the transient interface is
always a host network device assigned to the guest using VFIO (aka
"hostdev"); the persistent interface is always an emulated virtio NIC.
When support was initially added for <teaming>, it was written to
require that the transient/hostdev device be defined using <interface
type='hostdev'>; this was done because the virtio failover
implementation in QEMU and the virtio guest driver demands that the
two interfaces in the pair have matching MAC addresses, and the only
way libvirt can guarantee the MAC address of a hostdev network device
is to use <interface type='hostdev'>, whose main purpose is to
configure the device's MAC address before handing the device to
QEMU. (note that <interface type='hostdev'> in turn requires that the
network device be an SRIOV VF (Virtual Function), as that is the only
type of network device whose MAC address we can set in a way that will
survive the device's driver init in the guest).
It has recently come up that some users are unable to use <teaming>
because they are running in a container environment where libvirt
doesn't have the necessary privileges or resources to set the VF's MAC
address (because setting the VF MAC is done via the same device's PF
(Physical Function), and the PF is not exposed to libvirt's container).
At the same time, these users *are* able to set the VF's MAC address
themselves in advance of staring up libvirt in the container. So they
could theoretically use the <teaming> feature if libvirt just skipped
the "setting the MAC address" part.
Fortunately, that is *exactly* the difference between <interface
type='hostdev'> (which must be a "hostdev VF") and <hostdev> (a "plain
hostdev" - it could be *any* PCI device; libvirt doesn't know what type
of PCI device it is, and doesn't care).
But what is still needed is for libvirt to provide a small bit of
information on the QEMU commandline argument for the hostdev, telling
QEMU that this device will be part of a team ("failover pair"), and
the id of the other device in the pair.
To make both of those goals simultaneously possible, this patch adds
support for the <teaming> element to plain <hostdev> - libvirt doesn't
try to set any MAC addresses, and QEMU gets the extra commandline
argument it needs)
(actually, this patch adds only the parsing/formatting of the
<teaming> element in <hostdev>. The next patch will actually wire that
into the qemu driver.)

In commit 88957116c9 I've adapted
libvirt to QEMU's deprecation of -mem-path and -mem-prealloc and
switched to memory-backend-* even for system memory. My claim was
that that's what QEMU does under the hood anyway. And indeed it
was: see QEMU commit 900c0ba373aada4c13d47d95330aa72ec4067ba5 and
look at function create_default_memdev().
However, then commit d96c4d5f193e0e45beec80a6277728b32875bddb was
merged into QEMU. While it was fixing a bug, it also changed the
create_default_memdev() function in which it started turning off
use of canonical path (by setting
"x-use-canonical-path-for-ramblock-id" attribute to false). This
wasn't documented until QEMU commit
8db0b20415c129cf5e577a593a4a0372d90b7cc9. The path affects
migration - the same path has to be used on the source and on the
destination. Therefore, if there is old guest started with '-m X'
it has "pc.ram" block which doesn't use canonical path and thus
when migrating to newer QEMU which uses memory-backend-* we have
to turn off the canonical path explicitly. Otherwise,
"/objects/pc.ram" path would be expected by QEMU which doesn't
match the source.
Ideally, we would need to set it only for some machine types
(4.0 and older) because newer machine types already do what we
are doing. However, we treat machine types as opaque strings and
therefore we don't want to parse nor inspect their versions. But
then again, newer machine types already do what we are doing in
this commit, so when old machine types are deprecated and removed
we can remove our hack and forget it ever happened.
