[PATCH v3 0/5] Adding POWER11 CPU Support
by Narayana Murty N 13 May '25

13 May '25

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 12 May '25

12 May '25

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

[PATCH] qemu: fix qemuMigrationCapability enum
by Dmitry Frolov 12 May '25

12 May '25

Enum variable of type qemuMigrationCapability is checked for zero in src/qemu/qemu_migration_params.c:729. "if (item->optional) { ..." Actualy, QEMU_MIGRATION_CAP_XBZRLE enum constant has value 0. Thus, all uninitialized .optinnal fields of the static array qemuMigrationParamsFlagMap[] will be implicitly initialized with value 0 (QEMU_MIGRATION_CAP_XBZRLE). To my opinion, introducing a separate enum for optional capabilities, would be a better solution. Found by Linux Verification Center (linuxtesting.org) with SVACE.

[PATCH v2 0/5] docs: automated info about machine deprecation/removal info
by Daniel P. Berrangé 11 May '25

11 May '25

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 docs/about/deprecated.rst | 7 ++++ docs/about/removed-features.rst | 10 +++--- docs/conf.py | 39 +++++++++++++++++++++- include/hw/boards.h | 58 +++++++++++++++++++++------------ 4 files changed, 89 insertions(+), 25 deletions(-) -- 2.49.0

RFC: libvirt-tck bhyve/FreeBSD support
by Roman Bogorodskiy 09 May '25

09 May '25

Hi, I'd like to test the bhyve driver using libvirt-tck, which seems to be very useful both from the continuous integration perspective, and making the bhyve driver closer to other drivers to improve integration with other tooling. As a small proof-of-concept I made just a single test 060-persistent-lifecycle.t work with bhyve, though it was enough to highlight a bunch of issues. I've created a pull request on Gitlab: https://gitlab.com/libvirt/libvirt-tck/-/merge_requests/58 but apparently it's not very active there, so I'll briefly repeat it here as well. Issues I encountered: * Network Filters not supported It could be solved by implementing the network filters (obviously), but realistically it's probably not going to happen soon. I guess there are at least 3 options to solve that: - Add a test suite config knob to skip nwfilters - Don't fail the test suite on non-implemented list_nwfilters - In the bhyve driver, add a minimal implementation which always returns 0 rules * Hardcoded /dev/urandom RNG devices As the bhyve driver now supports virtio-rnd with /dev/random backend, should there be a configuration knob for libvirt-tck to override the RNG device definition? * Missing IDE device support Bhyve does not (and likely never will) support IDE devices, but supports SATA devices. Similar to the previous item, should there be a config knob? Or maybe just change default to sata? * Missing pty console support Bhyve does not support pty consoles. The bhyve driver currently supports the nmdm console, and bhyve also supports virtio-console and TCP socket connection which are not yet supported by the driver. * Firmware loader specification This is probably one of the trickiest ones. When no loader specified, the bhyve driver uses the bhyveload(8) loader which allows to boot FreeBSD guests only. That means that any other guest OS requires specifying the BHYVE_UEFI.fd firmware (or use grub-bhyve). I see two options for that: - A test suite/framework configuration knob (again) - Change the bhyve driver to default to BHYVE_UEFI.fd. I like this option for two reasons: it makes bhyve domain XMLs more compatible with other drivers, and also looks like a more reasonable default, because for example I don't run FreeBSD guests inside bhyve very often, so for most of my domains I have to set loader. It's a bit inconvenient that the firmware is not a part of bhyve and needs to be installed through the port, but we can make it possible to set the default firmware via the build option and allow to override that via the bhyve driver configuration, which should provide enough flexibility to users, I guess. Any thoughts and recommendations how to tackle this project appreciated. Thanks, Roman
