[PATCH 0/1] qemu: support VIR_DOMAIN_VCPU_ASYNC for live vCPU unplug
by Akash Kulhalli 23 Apr '26

23 Apr '26

This series adds asynchronous live vCPU unplug support for QEMU. It introduces a new flag `VIR_DOMAIN_VCPU_ASYNC` for the vCPU management APIs and adds a new libvirt event with the ID `VIR_DOMAIN_EVENT_ID_VCPU_REMOVED` that contains the vCPU ID. When async mode is requested, libvirt returns after successfully submitting the unplug request, instead of doing a short wait for the event to arrive (like its non-async counterpart); it reports the final outcome through domain events: successful completion emits a `vcpu-removed` event while guest-rejected unplug requests continue to emit `device-removal-failed`. This also addresses the current gap where a successful vCPU hot-unplug does not emit any domain event that `virsh event` (or any listener that uses the libvirt APIs) can observe. With the new event now in place, third-party API users can now watch for successful unplug completion events, instead of only seeing failure notification events. Async mode is limited to live vCPU unplug only. The series also threads the new event through the remote protocol and extends the user-facing tooling around it: both `virsh setvcpus` and `virsh setvcpu` gain a new `--async` flag, and `virsh event` gains `vcpu-removed` as an event that it can watch for and track successful unplug operations. All existing tests covering these paths have passed. A follow-up commit adding/enhancing explicit async test coverage is forthcoming.

[PATCH] bhyve: add virtio-console support
by Roman Bogorodskiy 22 Apr '26

22 Apr '26

Bhyve supports virtio-console devices using the following syntax: -s 2:0,virtio-console,org.qemu.guest_agent.0=/path/to/unix/socket,other.port=/other/socket,... There are two details about that to consider. The first one is that only up to 16 ports per console is supported. This is different from the default (31), so update the code to manually add the virtio-serial controllers with 16 ports. For the existing controllers, make sure to set max ports to 16 or error out if ports count greater than 16 was specified. The second one is that bhyve does not clean up UNIX sockets for these devices. So update virBhyveProcessStop() to remove leftover sockets. Not adding capabilities probing as the virtio-console device is available on all supported FreeBSD versions and on all supported arches.

[PATCH RFC 0/6] Add qemu-vnc support
by marcandre.lureau＠redhat.com 22 Apr '26

22 Apr '26

From: Marc-André Lureau <marcandre.lureau(a)redhat.com> Hi, This series allows to run the QEMU VNC server in a standalone process. The qemu-vnc binary is aimed to be released with QEMU 11.1. It is still being reviewed (https://patchew.org/QEMU/20260410-qemu-vnc-v2-0-231416f76dc3@redhat.com/) The standalone VNC activates automatically when a domain has both <graphics type='dbus'/> (bus mode) and <graphics type='vnc'/>, and the qemu-vnc binary is available. Comments welcome! Marc-André Lureau (6): qemu: add standalone VNC state directory qemu: add qemu-vnc configuration qemu: add qemu-vnc helper unit qemu: integrate standalone VNC in domain lifecycle qemu: wire up standalone VNC in driver APIs qemu: add tests for standalone VNC graphics po/POTFILES | 1 + src/qemu/libvirtd_qemu.aug | 1 + src/qemu/meson.build | 1 + src/qemu/qemu.conf.in | 8 + src/qemu/qemu_command.c | 2 + src/qemu/qemu_conf.c | 8 + src/qemu/qemu_conf.h | 2 + src/qemu/qemu_domain.c | 1 + src/qemu/qemu_domain.h | 2 + src/qemu/qemu_driver.c | 68 ++- src/qemu/qemu_extdevice.c | 13 +- src/qemu/qemu_hotplug.c | 12 + src/qemu/qemu_process.c | 40 +- src/qemu/qemu_vnc.c | 407 ++++++++++++++++++ src/qemu/qemu_vnc.h | 41 ++ src/qemu/test_libvirtd_qemu.aug.in | 1 + ...hics-vnc-standalone-p2p.x86_64-latest.args | 34 ++ ...phics-vnc-standalone-p2p.x86_64-latest.xml | 40 ++ .../graphics-vnc-standalone-p2p.xml | 39 ++ ...s-vnc-standalone-socket.x86_64-latest.args | 33 ++ ...cs-vnc-standalone-socket.x86_64-latest.xml | 40 ++ .../graphics-vnc-standalone-socket.xml | 40 ++ ...graphics-vnc-standalone.x86_64-latest.args | 33 ++ .../graphics-vnc-standalone.x86_64-latest.xml | 40 ++ .../graphics-vnc-standalone.xml | 40 ++ tests/qemuxmlconftest.c | 4 + tests/testutilsqemu.c | 9 + 27 files changed, 950 insertions(+), 10 deletions(-) create mode 100644 src/qemu/qemu_vnc.c create mode 100644 src/qemu/qemu_vnc.h create mode 100644 tests/qemuxmlconfdata/graphics-vnc-standalone-p2p.x86_64-latest.args create mode 100644 tests/qemuxmlconfdata/graphics-vnc-standalone-p2p.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/graphics-vnc-standalone-p2p.xml create mode 100644 tests/qemuxmlconfdata/graphics-vnc-standalone-socket.x86_64-latest.args create mode 100644 tests/qemuxmlconfdata/graphics-vnc-standalone-socket.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/graphics-vnc-standalone-socket.xml create mode 100644 tests/qemuxmlconfdata/graphics-vnc-standalone.x86_64-latest.args create mode 100644 tests/qemuxmlconfdata/graphics-vnc-standalone.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/graphics-vnc-standalone.xml -- 2.53.0

[PATCH v2] qemu: fix potential hang in qemuMigrationSrcCancelUnattended during reconnect
by Denis V. Lunev 22 Apr '26

22 Apr '26

When libvirtd reconnects to a running QEMU process that had an in-progress migration, qemuProcessReconnect first connects the monitor and only later recovers the migration job. During this window the async job is VIR_ASYNC_JOB_NONE, so any MIGRATION status events from QEMU are silently dropped by qemuProcessHandleMigrationStatus. If the migration was already cancelled or completed by QEMU during this window, no further events will be emitted. When qemuMigrationSrcCancelUnattended later restores the async job and calls qemuMigrationSrcCancel with wait=true, the wait loop calls qemuDomainObjWait (virCondWait with no timeout) and blocks forever waiting for an event that will never arrive. Fix this by re-querying QEMU migration state with qemuMigrationAnyRefreshStatus after restoring the async job but before calling qemuMigrationSrcCancel. If QEMU has already reached a terminal state, the cancel is skipped. Signed-off-by: Denis V.

[PATCH 0/3] build: Add option to disable building monolithic libvirtd
by Jim Fehlig 20 Apr '26

20 Apr '26

This is a V1 of an RFC series I posted earlier https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/D22C… As Daniel suggested, it leaves the semantics of existing 'driver_libvirtd' option unchanged and introduces a new 'libvirtd' option. Michal's comments also incorporated into V1. Patch 1 is new to the series. I suppose it can be pushed independently, unless I'm missing some meson magic.

[PATCH] virfile: safezero: handle posix_fallocate()'s EOPNOTSUPP
by Roman Bogorodskiy 20 Apr '26

20 Apr '26

FreeBSD 15.x updated posix_fallocate() to return EOPNOTSUPP instead of EINVAL when the operation is not supported. Quoting posix_fallocate(2): Previous versions of posix_fallocate used EINVAL to indicate that the operation is not supported by the file system, as specified in IEEE Std 1003.1 (“POSIX.1”) Base Specifications, Issue 7. IEEE Std 1003.1 (“POSIX.1”) Base Specifications, Issue 8 switched to requiring EOPNOTSUPP for this error case. ZFS adopted the latter convention in FreeBSD 15.0, and the remaining filesystems in base adopted it in FreeBSD 15.1. Update safezero_posix_fallocate() to handle this return value along with EINVAL to fix the waterfall down to safezero_slow() for filesystems that do not support that.

[PATCH v6 02/22] vhost: drop backend_features field
by Vladimir Sementsov-Ogievskiy 20 Apr '26

20 Apr '26

This field is mostly unused and sometimes confusing. We even have a TODO-like comment to drop it, the comment is removed in this commit. The field is used to held VHOST_USER_F_PROTOCOL_FEATURES for vhost-user and/or VHOST_NET_F_VIRTIO_NET_HDR for vhost-net (which may be vhost-user-net). But we can simply recalculate these two flags in place from hdev->features, and from net-client for VHOST_NET_F_VIRTIO_NET_HDR. Note: removing field from x-query-virtio-status result is incompatible change. We can do it because the command is unstable.
