5d18d740d8 qemu: support dirty ring feature
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].

d20ebdda28 qemu: Switch to -accel
We currently use -machine accel=XXX which is just a syntax sugar
for -accel XXX. The former doesn't allow specifying arguments for
accelerator, because all arguments passed to -machine are
treated as arguments of machine itself.

The -accel argument was introduced in QEMU commit
v2.9.0-rc0~70^2~19 and since our minimum required version is
newer (2.11.0) we can safely assume its existence and use it
without any capability.

3010a69226 qemu_command: Generate -mem-prealloc in one corner case more
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.

bbbf774fb2 tests/qemuxml2*/graphics-spice-timeout: skip CPU model check
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.

d73265af6e qemu_command: do not use host-nodes for system memory
Commit 88957116c9 switched to use
memory-backend-* for regular VM memory as well. That change indirectly
started using 'host-nodes' for system memory which results in QEMU
calling mbind() to bind the system memory to specific NUMA node if the
VM XML contains the configuration similar to this:

  ...
  <numatune>
    <memory mode='strict' nodeset='0'/>
  </numatune>
  ...

Once the VM was started with that configuration it was no longer
possible to change the memory NUMA nodeset.

swtpm_setup v0.7 or later is installed and may not have any effect
otherwise.

    target-i386: Register aliases for feature names with underscores

Libvirt names use underscores so we conditionally tranlate the
names when talking to new QEMU. Since the min QEMU was raised to
version 2.11.0, all QEMU versions we talk to expect hypens, so
the translation can be done unconditionally.

c9b13e0557 qemu: Use JSON directly for '-device'
Starting with QEMU-6.2 started accepting a JSON object as argument for
'-device' which will also become the only syntax considered stable by
qemu in the future.

Since libvirt was recently converted to generate the properties via JSON
to begin wit we can start using it on the commandline as well, by simply
enabling the QEMU_CAPS_DEVICE_JSON capability, which we do by probing
for the 'json-cli' feature flag of 'device_add'.

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
of tests validating the conversion to the old commandline options.

7300ccc9b3 conf: introduce support for acpi-bridge-hotplug feature
This change introduces a new libvirt sub-element <pci> under
<features> that can be used to configure all pci related features.
Currently the only sub-sub element supported by this sub-element is
'acpi-bridge-hotplug' as shown below:

<features>
  <pci>
    <acpi-bridge-hotplug state='on|off'/>
  </pci>
</features>

The above option is only available for the QEMU driver, for x86 guests
only. It is a global option, affecting all PCI bridge controllers on
the guest.

The 'acpi-bridge-hotplug' option enables or disables ACPI hotplug
support for cold-plugged pci bridges. Examples of bridges include the
PCI-PCI bridge (pci-bridge controller) for pc (i440fx) machinetypes,
or PCIe-PCI bridges and pcie-root-port controllers for q35
machinetypes.

For pc machinetypes in x86, this option has been available in QEMU
since version 2.1. Please see the following changes in qemu repo:

9e047b982452c6 ("piix4: add acpi pci hotplug support")
133a2da488062e ("pc: acpi: generate AML only for PCI0 devices if PCI
               bridge hotplug is disabled")

For q35 machinetypes, this was introduced in QEMU 6.1 with the
following changes in qemu repo:

(a) c0e427d6eb5fef ("hw/acpi/ich9: Enable ACPI PCI hot-plug")
(b) 17858a16950860 ("hw/acpi/ich9: Set ACPI PCI hot-plug as default on
                   Q35")

The reasons for enabling ACPI based hotplug for PCIe (q35) based
machines (as opposed to native hotplug) are outlined in (b). There are
use cases where users would still want to use native
hotplug. Therefore, this config option enables users to choose either
ACPI based hotplug or native hotplug for bridges (for example for pcie
root port controller in q35 machines).

Qemu capability validation checks have also been added along with
related unit tests to exercise the new conf option.

<controller type='pci' model='pci-root'>

'<target hotplug='off/on'/>' is only valid for pc (i440fx-based x86)
machinetypes and turns on the following command line option that is passed
to qemu for x86 guests:

with a 'hotplug' property. This property can be used to enable or disable
hotplug for the pci-root controller. For example, in order to disable hotplug
on the pci-root controller, one has to use set '<target hotplug='off'>' as
shown below:

<controller type='pci' model='pci-root'>
  <target hotplug='off'/>
</controller>

'<target hotplug='on'>' option would enable hotplug for pci-root controller.
This is also the default value. This option is only available for pc machine
types and is applicable for qemu/kvm accelerator only.This feature was

f931cb7f21 conf: Introduce virtio-mem <memory/> model
The virtio-mem is paravirtualized mechanism of adding/removing
memory to/from a VM. A virtio-mem-pci device is split into blocks
of equal size which are then exposed (all or only a requested
portion of them) to the guest kernel to use as regular memory.
Therefore, the device has two important attributes:

  1) block-size, which defines the size of a block
  2) requested-size, which defines how much memory (in bytes)
     is the device requested to expose to the guest.

The 'block-size' is configured on command line and immutable
throughout device's lifetime. The 'requested-size' can be set on
the command line too, but also is adjustable via monitor. In
fact, that is how management software places its requests to
change the memory allocation. If it wants to give more memory to
the guest it changes 'requested-size' to a bigger value, and if it
wants to shrink guest memory it changes the 'requested-size' to a
smaller value. Note, value of zero means that guest should
release all memory offered by the device. Of course, guest has to
cooperate. Therefore, there is a third attribute 'size' which is
read only and reflects how much memory the guest still has. This
can be different to 'requested-size', obviously. Because of name
clash, I've named it 'current' and it is dealt with in future
commits (it is a runtime information anyway).

In the backend, memory for virtio-mem is backed by usual objects:
memory-backend-{ram,file,memfd} and their size puts the cap on
the amount of memory that a virtio-mem device can offer to a
guest. But we are already able to express this info using <size/>
under <target/>.

Therefore, we need only two more elements to cover 'block-size'
and 'requested-size' attributes. This is the XML I've came up
with:

  <memory model='virtio-mem'>
    <source>
      <nodemask>1-3</nodemask>
      <pagesize unit='KiB'>2048</pagesize>
    </source>
    <target>
      <size unit='KiB'>2097152</size>
      <node>0</node>
      <block unit='KiB'>2048</block>
      <requested unit='KiB'>1048576</requested>
    </target>
    <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
  </memory>

I hope by now it is obvious that:

  1) 'requested-size' must be an integer multiple of
     'block-size', and
  2) virtio-mem-pci device goes onto PCI bus and thus needs PCI
     address.

Then there is a limitation that the minimal 'block-size' is
transparent huge page size (I'll leave this without explanation).

SeaBIOS >= 1.11 has built-in support for outputting to the serial

is 2.11.0, which bundled SeaBIOS 1.11. Thus we have no need to
use '-device sga' anymore.

This change results in a slight layout difference for option ROMs
in memory, however, it does not affect the migration data stream
format on the wire and once migration is complete the target QEMU
memory layout for ROMs matches the source QEMU once again.

dc0b9c8376 qemu: block: Pass discard requests through the copy-on-read block filter
We need to pass the 'trim' requests through the copy-on-read filter so
if a user configures a discard policy on the disk the requests get
through to the appropriate format layer in the blockdev tree.

c6d7b9a261 qemu: Don't use memory-backend-memfd for NVDIMMs
If guest is configured to use memfd then the function that build
memory-backend-* part of command line will put
memory-backend-memfd, always. Even for NVDIMMs. This is not
correct, because NVDIMMs need a backing path (usually to a real
host NVDIMM device). Therefore, regardless of memfd being
requested, we have to stick with memory-backend-file.
