[PATCH v1] tests: add capabilities for QEMU 10.0.0 on s390x

by Shalini Chellathurai Saroja

Let us introduce the xml and reply files for QEMU 10.0.0 on s390x. Notable changes: - new s390-ccw-virtio-10.0 machine type - old machine types (2.4 - 2.8) dropped - new CPU models - New devices: - virtio-mem-ccw - chardev now supports qemu-vdagent Signed-off-by:

[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] virbitmap: Change return type of virBitmapToData to void

[PATCH] USB hostdev: allow addressing by port

by Maximilian Martin

From: Maximilian Martin <maximilian_martin(a)gmx.de> 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 v2 0/4] 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 9.2.1 to include POWER11 in the capabilities tests. Patch Summary: Patch 0001: Remove test cases for the QEMU-dropped pseries-2.7 machine. Patch 0002: Add capabilities test support for QEMU 9.2.0 on PPC64. Patch 0003: Add POWER11 CPU model support. Patch 0004: Add POWER11 host model support. 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") Signed-off-by: Narayana Murty N <nnmlinux(a)linux.ibm.com> ---- Changelog: -V1:https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/4A3IND2QP5CE654XE755ICRZKLUNYXAE/ *Addressed v2 patch readability issues. *Fixed the Unit test failures at individual patch levels.

[PATCH v3 00/20] Add qemu RDP server support

by marcandre.lureau＠redhat.com

From: Marc-André Lureau <marcandre.lureau(a)redhat.com> Hi, This patch series offers an out-of-process Remote Desktop Protocol (RDP) server solution utilizing QEMU's -display dbus interface, offering improved modularity and potential security benefits compared to built-in server. This initiative was spearheaded by Mihnea Buzatu during the QEMU Summer of Code 2023. The project's goal was to develop an out-of-process RDP server using the -display dbus interface, implemented in Rust. Given that the IronRDP crate lacked some server support at the time, investments in IronRDP were required. I finally released an initial v0.1 version of qemu-rdp on crates.io (https://crates.io/crates/qemu-rdp). That should allow more people to review and evaluate the state of this work. On unix systems, with cargo/rust toolchain installed, it should be as easy as running "cargo install qemu-rdp", apply this patch series for libvirt, set the "rdp_tls_x509_cert_dir" location for your TLS certificates, and configure a VM with both dbus & rdp graphics (run "virsh domdisplay DOMAIN" to get the display connection details). Thanks for the reviews & feedback! v3: thanks to Martin Kletzander review - drop "[PATCH v2 05/21] qemu: fall-through for unsupported graphics" patch - drop extra \n when reporting dbus-daemon log - check password != NULL or VIR_ERR_INTERNAL_ERROR - remove some needless #include/leftover - remove some needless g_auto pointer - rebased - add r-b tags v2: thanks to Daniel review - drop extra error report from "qemu: report an error for unsupported graphics" - replace g_return pre-conditions with ATTRIBUTE_NONNULL - improve "qemu/dbus: keep a connection to the VM D-Bus" to also reconnect - use domainLogContext for logging (for virtiofs as well) - check for qemu-rdp availabilty for setting 'rdp' capability - make dbus-addr qemu-rdp capability mandatory - rebased - add r-b tags Marc-André Lureau (20): build-sys: drop -Winline when optimization=g build: fix -Werror=maybe-uninitialized qemu-slirp: drop unneeded check for OOM util: annotate non-null arguments for virGDBusCallMethod() qemu: add rdp state directory qemu: add qemu RDP configuration conf: parse optional RDP username & password conf: generalize virDomainDefHasSpiceGraphics qemu: use virDomainDefHasGraphics qemu: add RDP ports range allocator qemu: limit to one <graphics type='rdp'> qemu/virtiofs: use domainLogContext qemu/dbus: keep a connection to the VM D-Bus qemu/dbus: log daemon stdout/err, use domainLogContext qemu: validate RDP configuration qemu: add qemu-rdp helper unit qemu: pass virQEMUDriverConfig to capabilities qemu: add 'rdp' capability if qemu-rdp is available qemu: add RDP support tests: add qemu <graphics type='rdp'/> test docs/formatdomain.rst | 25 +- meson.build | 7 +- po/POTFILES | 1 + src/conf/domain_conf.c | 28 +- src/conf/domain_conf.h | 5 +- src/conf/schemas/domaincommon.rng | 10 + src/libvirt_private.syms | 2 +- src/qemu/libvirtd_qemu.aug | 7 + src/qemu/meson.build | 1 + src/qemu/qemu.conf.in | 31 ++ src/qemu/qemu_capabilities.c | 24 +- src/qemu/qemu_capabilities.h | 12 +- src/qemu/qemu_command.c | 8 +- src/qemu/qemu_conf.c | 56 ++- src/qemu/qemu_conf.h | 13 + src/qemu/qemu_dbus.c | 69 ++- src/qemu/qemu_dbus.h | 3 + src/qemu/qemu_domain.c | 1 + src/qemu/qemu_domain.h | 4 + src/qemu/qemu_driver.c | 20 + src/qemu/qemu_extdevice.c | 46 +- src/qemu/qemu_hotplug.c | 51 ++- src/qemu/qemu_hotplug.h | 1 + src/qemu/qemu_process.c | 169 ++++++- src/qemu/qemu_rdp.c | 424 ++++++++++++++++++ src/qemu/qemu_rdp.h | 73 +++ src/qemu/qemu_slirp.c | 6 -

[PATCH 0/3] ch: monitor daemonization, sync after reboot, and shutdown fixes

by Kirill Shchetiniuk

1. Run CH monitor as a daemon Made the monitor process daemonized to prevent VM termination if the CH driver crashes. Added pidfile for daemon's pid aquiring and tracking as well as its init. 2. Update domain info after reboot Fixed an issue where domain properties (e.g., serial console path) were not updated after VM reboot. Added VIR_CH_EVENT_VM_REBOOTED handling to keep the transient domain definition consistent. 3. Update VM shutdown event handler VM monitor was still up even if VM was shut off, which led to an inability to start the domain again. virsh # shutdown ch-test Domain 'ch-test' is being shutdown virsh # list Id Name State ------------------------------ 722117 ch-test shut off Ensured the CH monitor process terminates along with the VM shutdown (e.g., executed using virsh). Updated virCHEventStopProcess to have proper job type.

[PATCH 1/5] virpci: Switch to an implementation using libpciaccess

by Alexander Shursha

The current virpci code uses the Linux-specific sysfs subsystem, which makes it impossible to use on other Unix-like systems. The libpciaccess library provides a cross-platform API for accessing the PCI bus. Employ it to make the code portable. This makes libpciaccess a non-optional dependency of libvirt.
