[PATCH 0/2] network: support NAT networking for FreeBSD/pf
by Roman Bogorodskiy
This series implements NAT networks support for FreeBSD using the Packet
Filter (pf) firewall.
The commit messages provide high-level details and limitations of the
current implementation, and I'll use this cover letter to provide some
more technical details and describe testing I have performed for this
change.

[PATCH 0/4] Allow xml-configured coredump format on VM crash
by Nikolai Barybin
When libvirt processes VM crash event it always dumps core in raw
format.
This series makes it possible to configure dump format via domain xml.
This would be especcialy helpful for Windows guests, because it requires
a lot effort to convert raw dump into wingdb.

[PATCH 0/4] USB hostdev: allow addressing by port
by Maximilian Martin
This resubmission splits up the previous patch into multiple patches and
incorporates review comments from Michal Prívozník.
Currently, only vendor/product and bus/device matching are supported for USB host
devices. Neither of these provide a stable and persistent way of assigning a guest
a specific host device. Vendor/product can be ambiguous. Device numbers change on
every enumeration.
This patch adds a bus/port matching, which allows a specific port on the host to be
specified using the dotted notation found in Linux's "devpath" sysfs attribute.
This patch is based on the previous work of Thomas Hebb: https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/message/7...

[PATCH 0/3] qemu: Replace usb-storage with usb-bot
by Akihiko Odaki
usb-storage is a compound device that automatically creates a USB mass
storage device and a SCSI device as its backend. Unfortunately it lacks
some configuration options that are usually present with a SCSI device,
and cannot represent CD-ROM in particular.
Replace usb-storage with usb-bot, which can be combined with a manually
created SCSI device. libvirt will configure the SCSI device in a way
identical with how QEMU does for usb-storage except that now it respects
a configuration option to represent CD-ROM.

[PATCH v3 0/6] qemu: acpi-generic-initiator support
by Andrea Righi
= Overview =
This patch set introduces support for acpi-generic-initiator devices,
supported by QEMU [1].
The acpi-generic-initiator object is required to support Multi-Instance GPU
(MIG) configurations on NVIDIA GPUs [2]. MIG enables partitioning of GPU
resources into multiple isolated instances, each requiring a dedicated NUMA
node definition.
= Implementation =
This patch set implements the libvirt counterpart to the QEMU feature,
enabling users to configure acpi-generic-initiator objects within libvirt
domain XML.
This includes:
- adding XML syntax to define acpi-generic-initiator objects,
- resolving the acpi-generic-initiator definitions into the proper QEMU
command-line arguments,
- ensuring compatibility with existing NUMA configuration.
= Example =
- Domain XML:
```

Question about SEV* guests and automatic firmware selection
by Jim Fehlig
Hi All,
While investigating an internal bug report, we noticed that a minimal firmware
auto-selection configuration along with SEV* fails to find a match. E.g. the
following config
<domain type="kvm">
<os firmware="efi">
<type arch="x86_64" machine="q35">hvm</type>
<boot dev="hd"/>
</os>
<launchSecurity type="sev">
<policy>0x07</policy>
</launchSecurity>
...
</domain>
Fails with "Unable to find 'efi' firmware that is compatible with the current
configuration". A firmware that should match has the following json description
{
"description": "UEFI firmware for x86_64, with AMD SEV",
"interface-types": [
"uefi"
],
"mapping": {
"device": "flash",
"mode": "stateless",
"executable": {
"filename": "/usr/share/qemu/ovmf-x86_64-sev.bin",
"format": "raw"
}
},
"targets": [
{
"architecture": "x86_64",
"machines": [
"pc-q35-*"
]
}
],
"features": [
"acpi-s4",
"amd-sev",
"amd-sev-es",
"amd-sev-snp",
"verbose-dynamic"
],
"tags": [
]
}
Auto-selection works fine if I specify a 'stateless' firmware, e.g. amend the
above config with
<os firmware="efi">
<type arch="x86_64" machine="q35">hvm</type>
<loader stateless="yes"/>
<boot dev="hd"/>
</os>
Being unfamiliar with the firmware auto-selection code, I tried the below naive
hack, which only led to test failures and the subsequent runtime error "unable
to find any master var store for loader: /usr/share/qemu/ovmf-x86_64-sev.bin".
Should auto-selection work with the minimal config, or is it expected that user
also specify a stateless firmware?
Regards,
Jim

[PATCH RESEND 0/6] Add support for configuring PCI high memory MMIO size
by Matthew R. Ochs
Resending: Series has been re-based over latest upstream.
This patch series adds support for configuring the PCI high memory MMIO
window size for aarch64 virt machine types. This feature has been merged
into the QEMU upstream master branch [1] and will be available in QEMU 10.0.
It allows users to configure the size of the high memory MMIO window above
4GB, which is particularly useful for systems with large amounts of PCI
memory requirements.
The feature is exposed through the domain XML as a new PCI feature:
<features>
<pci>
<highmem-mmio-size unit='G'>512</highmem-mmio-size>
</pci>
</features>
When enabled, this configures the size of the PCI high memory MMIO window
via QEMU's highmem-mmio-size machine property. The feature is only
available for aarch64 virt machine types and requires QEMU support.
This series depends on [2] and should be applied on top of those patches.
For your convenience, this series is also available on Github [3].

[PATCH v3 0/5] Adding POWER11 CPU Support
by Narayana Murty N
This patch series introduces the necessary changes to
support the power11 CPU and power11 host in libvirt.
Additionally, it updates the QEMU capabilities with
the latest QEMU version v10.0.0-rc2 to include power11
in the capabilities tests.During testing of v2 patches
found a bug in qemu which sets wrong default cpu for
pre-9.0 machines, that was fixed in qemu v10.0.0-rc2.
Patch Summary:
Patch 0001: tests: Pin pseries-2.7 tests to the version 7.0.
Patch 0002: Fix: qemuhotplugtest Set the cpu version at source as POWER9.
Patch 0003: Add capabilities test support for QEMU 10.0.0 on PPC64.
Patch 0004: Add POWER11 CPU model support.
Patch 0005: Add POWER11 host model support and accept case-insensitive.
The corresponding patches for the Linux kernel and QEMU
are already upstream. Relevant links are provided below:
Linux kernel patches:
1. Linux P11 support: commit c2ed087ed35c ("powerpc: Add Power11 architected and raw mode")
2. Linux P11 KVM support: commit 96e266e3bcd6 ("KVM: PPC: Book3S HV: Add Power11 capability support for Nested PAPR guests")
Qemu patches:
3. Qemu P11 support: commit 273db89bcaf4 ("ppc/pseries: Add Power11 cpu type")
4. Qemu P11 DD02.0 support: commit c0d964076c3e ("target/ppc: Add Power11 DD2.0 processor")
5. Qemu pre-9.0 pseries michines changing default cpu with Qemu commit 1490d0bcdfcb ("ppc/spapr: fix default cpu for pre-9.0 machines.").

[PATCHv2 0/5] qemu: Introduce nvme disk emulation support
by honglei.wang＠smartx.com
From: hongleiwang <honglei.wang(a)smartx.com>
QEMU has supported nvme disk emulation for a long time,
see: https://qemu-project.gitlab.io/qemu/system/devices/nvme.html.
The following patches introduce nvme-ns disk bus type:
A disk with nvme-ns as bus is represented as an nvme namespace
and needs to be attached to an nvme controller. In XML, it can be
used like this:
<devices>
...
<disk type='file' device='disk'>
<driver name='qemu' type='raw'/>
<source file='/tmp/data.img'/>
<target dev='nvmensa' bus='nvme-ns'/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
<controller type='nvme' index='0'>
<serial>nvme-controller-serial-value</serial>
<address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/>
</controller>
...
</devices>
Signed-off-by: ray <honglei.wang(a)smartx.com>

Compared to patch v1, this version removes the nvme bus type implementation
and keeps only the nvme controller + nvme-ns bus approach.
ray (5):
qemu: Add support for NVMe namespace disk bus type
qemu_capabilities: Add support for nvme-ns bus capabilities
schema: Add nvme controller and nvme-ns bus defination
tests: Add test case for nvme-ns device configuration
NEWS: Document qemu nvme disk emulation feature

[PATCH v2 0/5] docs: automated info about machine deprecation/removal info
by Daniel P. Berrangé
Since we deprecate and remove versioned machine types on a fixed
schedule, we can automatically ensure that the docs reflect the
latest version info, rather than requiring manual updates on each
dev cycle.
The first patch in this series removes the hack which postponed
automatic removal of versioned machine types to the 10.1.0 release,
since we're now in the 10.1.0 dev cycle.
The second patch in this series fixes the logic to ensure dev snapshots
and release candidates don't have an off-by-1 error in setting
deprecation and removal thresholds - they must predict the next formal
release version number.
The following three patches deal with the docs stuff.
With this series applied all versioned machine types prior to 4.1
are now removed (hidden). We can delete the code at our leisure.
Changed in v2:
- Remove hack that temporarily postponed automatic deletion
of machine types
- Fix docs version info for stable bugfix releases
Daniel P. Berrangé (5):
Revert "include/hw: temporarily disable deletion of versioned machine
types"
include/hw/boards: cope with dev/rc versions in deprecation checks
docs/about/deprecated: auto-generate a note for versioned machine
types
docs/about/removed-features: auto-generate a note for versioned
machine types
include/hw/boards: add warning about changing deprecation logic
