[PATCH 0/2] docs: improve isa-debugcon example
by Laszlo Ersek 18 May '23

18 May '23

The feature from libvirt 8.1 that the OVMF debug log can be captured with native domain XML elements is super useful, but the example snippet in the documentation is more difficult to use than necessary. Improve it. Cc: "Daniel P. Berrangé" <berrange(a)redhat.com> Cc: Andrea Bolognani <abologna(a)redhat.com> Thanks!

[PATCH V3 0/3] migration: add qemu parallel migration options
by Jiang Jiacheng 18 May '23

18 May '23

Add compress method zlib and zstd for parallel migration and new migration options to set qemu's parameter related with parallel migration(multifd-compression, multifd-zlib-level and multifd-zstd-level). These parameters has been supported by QEMU since 5.0. v3 of: https://listman.redhat.com/archives/libvir-list/2023-February/237604.html diff to v2: * merge the processing of new method into 'qemuMigrationParamsSetCompression' * improve descriptions for the new options.

[PATCH v3] vfio/pci: Propagate ACPI notifications to user-space via eventfd
by Grzegorz Jaszczyk 17 May '23

17 May '23

From: Grzegorz Jaszczyk <jaz(a)semihalf.com> To allow pass-through devices receiving ACPI notifications, permit to register ACPI notify handler (via introduced new ioctl) for a given device. The handler role is to receive and propagate such ACPI notifications to the user-space through the user provided eventfd. This allows VMM to receive and propagate them further to the VM, where the actual driver for pass-through device resides and can react to device specific notifications accordingly. The eventfd usage ensures VMM and device isolation: it allows to use a dedicated channel associated with the device for such events, such that the VMM has direct access. Since the eventfd counter is used as ACPI notification value placeholder, the eventfd signaling needs to be serialized in order to not end up with notification values being coalesced. Therefore ACPI notification values are buffered and signalized one by one, when the previous notification value has been consumed. Signed-off-by: Grzegorz Jaszczyk <jaz(a)semihalf.com> --- Changelog v2..v3: - Fix compilation warnings when building with "W=1" Changelog v1..v2: - The v2 implementation is actually completely different then v1: instead of using acpi netlink events for propagating ACPI notifications to the user space take advantage of eventfd, which can provide better VMM and device isolation: it allows to use a dedicated channel associated with the device for such events, such that the VMM has direct access. - Using eventfd counter as notification value placeholder was suggested in v1 and requires additional serialization logic introduced in v2. - Since the vfio-pci supports non-ACPI platforms address !CONFIG_ACPI case. - v1 discussion: https://patchwork.kernel.org/project/kvm/patch/20230307220553.631069-1-jaz@… --- drivers/vfio/pci/vfio_pci_core.c | 214 +++++++++++++++++++++++++++++++ include/linux/vfio_pci_core.h | 11 ++ include/uapi/linux/vfio.h | 15 +++ 3 files changed, 240 insertions(+) diff --git a/drivers/vfio/pci/vfio_pci_core.c b/drivers/vfio/pci/vfio_pci_core.c index a5ab416cf476..2d6101e89fde 100644 --- a/drivers/vfio/pci/vfio_pci_core.c +++ b/drivers/vfio/pci/vfio_pci_core.c @@ -10,6 +10,7 @@ #define pr_fmt(fmt) KBUILD_MODNAME ": " fmt +#include <linux/acpi.h> #include <linux/aperture.h> #include <linux/device.h> #include <linux/eventfd.h> @@ -679,6 +680,70 @@ void vfio_pci_core_disable(struct vfio_pci_core_device *vdev) } EXPORT_SYMBOL_GPL(vfio_pci_core_disable);

[PATCH] virmockstathelpers: Adapt to musl-1.2.4
by Michal Privoznik 15 May '23

15 May '23

With musl-1.2.3: I get the following macros defined (from $builddir/meson-config.h): #define WITH_LSTAT 1 #define WITH_LSTAT64 1 #define WITH_LSTAT_DECL 1 #define WITH_STAT 1 #define WITH_STAT64 1 #define WITH_STAT_DECL 1 #define WITH___LXSTAT 1 #define WITH___LXSTAT64 1 #define WITH___XSTAT 1 #define WITH___XSTAT64 1 which in turn means the virmockstathelpers.c ends up defining: MOCK_STAT64 MOCK_LSTAT64 But with musl-1.2.4 everything changes and the set of defined macros gets simplified to: #define WITH_LSTAT 1 #define WITH_LSTAT_DECL 1 #define WITH_STAT 1 #define WITH_STAT_DECL 1 #define WITH___LXSTAT 1 #define WITH___XSTAT 1 which results in no MOCK_* macros defined in virmockstathelpers.c, i.e. no stat() mocking, nada. The reason for this simplification are thess musl commits [1][2] which removed all 64 bit aliases. And that's not what our logic for deciding what flavor of stat() to mock counted with. Nevertheless, we do build with Alpine Linux in our CI, so how come we don't see this problem there? Well, simply because Alpine Linux maintainers decided to revert the commits [3][4]. But on distributions that use vanilla musl, this problem can be seen easily. 1: https://git.musl-libc.org/cgit/musl/commit/?id=246f1c811448f37a44b41cd8df8d… 2: https://git.musl-libc.org/cgit/musl/commit/?id=25e6fee27f4a293728dd15b65917… 3: https://git.alpinelinux.org/aports/commit/main/musl?id=6a5563fbb45b3d9d6067… 4: https://git.alpinelinux.org/aports/commit/main/musl?id=a089bd852f8983623fa8… Resolves: https://bugs.gentoo.org/906167 Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- tests/virmockstathelpers.c | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) diff --git a/tests/virmockstathelpers.c b/tests/virmockstathelpers.c index 5b1f3b08a7..a02ee04503 100644 --- a/tests/virmockstathelpers.c +++ b/tests/virmockstathelpers.c @@ -64,6 +64,10 @@ * building on Apple Silicon (aarch64) those functions are missing * from the header altogether and should not be mocked. * + * Starting from 1.2.4, the musl library dropped 64-bit aliases, i.e. there's + * no stat64() only stat().

[RFC PATCH] hostdev:Introduce vDPA device to hostdev subsystem as a new subtype
by libai 10 May '23

10 May '23

The following is the xml of vdpa device: <devices> <hostdev mode='subsystem' type='vdpa'> <source dev='/dev/vhost-vdpa-0'/> </hostdev> </devices> And the command line passed to QEMU is as follows: -device {"driver":"vhost-vdpa-device-pci","vhostdev":"/dev/vhost-vdpa-0"} This solution is selected according to the previous discussion on the solution of supporting the vDPA device.

[libvirt PATCH 0/5] qemu: Find helpers at runtime
by Andrea Bolognani 10 May '23

10 May '23

This removes the need to have them present in the build environment and makes things more flexible. Note that we currently *do not* have the helpers available in most CI environments, or have BuildRequires for them in the spec file. That only works for Fedora and RHEL because the hardcoded fallback paths happen to match those used on those distributions: everywhere else, the choice is to either ensure that the additional packages are installed in the build environment or to produce a build of libvirt that can't use the corresponding features out of the box.

[PATCH] logging: Provide empty VIRTLOGD_ARGS in the unit file
by Michal Privoznik 09 May '23

09 May '23

For all our daemons, we provide VIRXXXD_ARGS env var in the unit file. The variable can then be overridden in corresponding file: EnvironmentFile=-@initconfdir@/virtxxxd The daemon is then executed as: ExecStart=@sbindir@/virtxxxd $VIRTXXXD_ARGS But virlogd is exception, for no good reason. And while there are probably no arguments we want to pass to virtlogd by default, just mimic what we do for say virtlockd, where we also don't pass any default argument.

[RFC PATCH] hostdev:Introduce vDPA device to hostdev subsystem as a new subtype
by libai 06 May '23

06 May '23

The following is the xml of vdpa device: <devices> <hostdev mode='subsystem' type='vdpa'> <source dev='/dev/vhost-vdpa-0'/> </hostdev> </devices> And the command line passed to QEMU is as follows: -device {"driver":"vhost-vdpa-device-pci","vhostdev":"/dev/vhost-vdpa-0"} This solution is selected according to the previous discussion on the solution of supporting the vDPA device.

[libvirt PATCH] .gitlab-ci.yml: Fix Leap 15.4 codestyle job
by Erik Skultety 05 May '23

05 May '23

Commit a3cc0e9ceb3e forgot to tweak the codestyle job so that we refer to Leap 15.4 as Leap 15 (with the recent change in lcitool). However, it was easy to miss as that job is not managed by the manifest.

[PATCH] qemu: hotplug: Reorder setup of disk backend metadata
by Peter Krempa 05 May '23

05 May '23

The regular VM startup code first calls the setup of the disk backing chain as defined in the XML and then calls the function to load the rest of the backing chain from the image metadata. The hotplug code did it the other way around, thus causing a failure when attempting to attach a QCOW2 image via FD passing. Reorder the hotplug code to have the same order.
