Dirty ring feature was introduced in qemu-6.1.0, this patch
add the corresponding feature named 'dirty-ring', which enable
dirty ring feature when starting VM.
To enable the feature, the following XML needs to be added to
the guest's domain description:
<features>
<kvm>
<dirty-ring state='on' size='xxx'>
</kvm>
</features>
If property "state=on", property "size" must be specified, which
should be power of 2 and range in [1024, 65526].

When libvirt added support for firewalld, all iptables/ebtables rules
were added via the firewalld "passthrough" API when firewalld was
enabled (the "firewalld backend"), or run directly by libvirt when
firewalld was disabled (the so-called "direct
backend"). virfirewalltest.c dutifully ran each test twice, once with
the each backend enabled.
But commit b19863640d changed the code to *always* directly run
iptables/ebtables commands, and never use the firewalld passthrough
API, effectively making the direct and firewalld backends identical,
except that when libvirt receives notice that firewalld has restarted
or reloaded its rules, the firewalld backend sends an extra "iptables
-V" command via firewalld's passthrough API (and waits for a response)
prior to running all the rest of the iptables commands directly; this
assures that a newly-restarted firewalld has finished its work on the
filter tables before libvirt starts messing with it. (Because this
code is only executed in response to an event from dbus, it isn't
tested in the unit tests).
In spite of this, we still go through all the virfirewall tests twice
though - once for the direct backend, and once for the firewalld
backend, even though these take the same codepath.
In commit b19863640d I had left this double-testing in thinking that
someday we might go back to actually doing something useful with the
firewalld backend in the course of adding support for native nftables,
but I've now realized that for the case of nftables we will be *even
more* divorced from firewalld, so there is really no point in keeping
this code around any longer. (It's likely/probable that the tests will
be done twice again in the future, but it will be enough different
that it is better to remove this code and re-implement from scratch
when adding the nftables backend, rather than trying to directly
modify the existing code and end up with something even more
confusing).
This patch eliminates all the test duplication in virfirewalltest.c,
including mocking dbus, which is unnecessary since none of the tests
use dbus (for now we ensure that by explicitly setting the virfirewall
backend to DIRECT before any of the tests have run. Eventually the
concept of a "firewalld backend" will disappear completely, but that's
for another patch.)

The opening of files for FD passing for a chardev backend was
historically done in the function which is formatting the commandline.
This has multiple problems. Firstly the function takes a lot of
parameters which need to be passed through the commandline formatters.
This made the 'qemuBuildChrChardevStr' extremely unappealing to the
extent that we have multiple other custom formatters in places which
didn't really want to use the function.
Additionally the function is also creating files in the host in certain
configurations which is wrong for a commandline formatter to do. This
meant that e.g. not all chardev test cases can be converted to use
DO_TEST_CAPS_LATEST as we attempt to use such code path and attempt to
create files outside of the test directory.
This patch moves the opening of the filedescriptors from
'qemuBuildChrChardevFileStr' into a new helper
'qemuProcessPrepareHostBackendChardevOne' which is called using
'qemuDomainDeviceBackendChardevForeach'.
To preserve test behaviour we also have another instance
'testPrepareHostBackendChardevOne' which is populating mock
filedescriptors.

Commit bc24810c2c modified code querying blockstats to use the

are not attached to a frontend such as block copy and backup scratch
images.
Unfortunately that broke the old blockstats because if 'query-nodes' is
enabled qemu doesn't output the 'qdev' parameter which our code used for
matching to the disk and also qemu neglects to populate the frontend
stats at all so we can't even switch to using nodename for matching.
To fix this we need to do two calls, one with 'query-nodes' disabled
using the old logic to populate everything and then an additional one
which populates all the remaining images.

When guest has NUMA nodes and QEMU is new enough to report
default RAM ID then ideally we would use -numa memdev= combined
with memory-backend-* combo becasue -mem-path/-mem-prealloc/-numa
mem are deprecated. Well, there is one problem - the .memdev=
attribute is machine type dependent (just look at arguments of
virQEMUCapsGetMachineNumaMemSupported()) and to ensure backwards
compatibility we prefer -numa mem= over -numa memdev=.
But there was one corner case when -mem-prealloc was requested
but not generated on the cmd line. It all starts with
qemuBuildMemCommandLine() which generates just '-m XXX' and
because it sees defaultRAMid and guest NUMA nodes greater than
zero it does nothing more.
Then, qemuBuildNumaCommandLine() sees that -numa mem= is still
supported for given machine type and nothing else set
@needBackend thus qemuBuildMemPathStr() is called which output
-mem-prealloc only in a few cases assuming it was outputted
earlier.

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.

While invalid values need to be ignored when presenting VPD data to the
user, it would be good to attempt to parse a valid portion of the VPD
instead of marking it invalid as a whole.
Based on a mailing list discussion, the set of accepted characters is
extended to the set of printable ASCII characters.
https://listman.redhat.com/archives/libvir-list/2021-October/msg01043.html
The particular example encountered on real hardware was multi-faceted:
* "N/A" strings present in read-only fields. This would not be a useful
valid value for a field (especially if a unique serial number is
expected), however, it was decided to delegate handling of those kinds
of values to higher-level software;
* "4W/1W PCIeG2x4" - looks like some vendors use even more printable
characters in the ASCII range than we currently allow. Since the
PCI/PCIe VPD specs mention alphanumeric characters without specifying
the full character set, it looks like this is ambiguous for vendors
and they tend to use printable ASCII characters;
* 0xFF bytes present in VPD-W field values. Those bytes do not map to
printable ASCII code points and were probably used by the vendor as

* RV and RW fields must be at the last position in their respective
section (per the conditions in the spec). Therefore, the parser now
stops iterating over fields as soon as it encounters one of those
fields and checks whether the end of the resource has been reached;
* The lack of the RW field is not treated as a parsing error since we
can still extract valid data even though this is a PCI/PCIe VPD spec
violation;
* Individual fields must have a valid length - the parser needs to check
for invalid length values that violate boundary conditions of the
resource.
* A zero-length field may be the last one in the resource, however, the
boundary check is currently too strict to allow that.

Normally a change which changes a commandline output should be happening
only after the impacted real-caps test files are forked in the version
preceding the change, but in this case it's not necessary as the logic
for generating the device properties stays identical and we just change
the output format (avoid conversion). Additionally we still have a lot

The types for the special fields of the 'virtio-blk-pci' according to
QEMU are:
iothread=<link<iothread>>
ioeventfd=<bool> - on/off (default: true)
event_idx=<bool> - on/off (default: true)
scsi=<bool> - on/off (default: false)
num-queues=<uint16> - (default: 65535)
queue-size=<uint16> - (default: 256)
For all disks we also use the following properties (based on 'scsi-hd'):
device_id=<str>
share-rw=<bool> - (default: false)
drive=<str> - Node name or ID of a block device to use as a backend
chardev=<str> - ID of a chardev to use as a backend <- vhost-user-blk-pci
bootindex=<int32>
logical_block_size=<size> - A power of two between 512 B and 2 MiB (default: 0)
physical_block_size=<size> - A power of two between 512 B and 2 MiB (default: 0)
wwn=<uint64> - (default: 0)
rotation_rate=<uint16> - (default: 0)
vendor=<str>
product=<str>
removable=<bool> - on/off (default: false)
write-cache=<OnOffAuto> - on/off/auto (default: "auto")
cyls=<uint32> - (default: 0)
heads=<uint32> - (default: 0)
secs=<uint32> - (default: 0)
bios-chs-trans=<BiosAtaTranslation> - Logical CHS translation algorithm, auto/none/lba/large/rechs (default: "auto") <- ide-hd
serial=<str>
werror=<BlockdevOnError> - Error handling policy, report/ignore/enospc/stop/auto (default: "auto")
rerror=<BlockdevOnError> - Error handling policy, report/ignore/enospc/stop/auto (default: "auto")
The 'wwn' field is changed from a hex string to a number since qemu
actually treats it as a number.
