The 12.5.0 release of both libvirt and libvirt-python is tagged and signed tarballs are available at https://download.libvirt.org/ https://download.libvirt.org/python/ Thanks everybody who helped with this release by sending patches, reviewing, testing, or providing feedback. Your work is greatly appreciated. * New features * bhyve: Extend the guest agent support The bhyve driver now supports several APIs on top of the guest agent: * Getting and setting guest OS SSH keys * Setting guest OS user's password * Getting and setting guest OS time Additionally, domain rebooting and shutting down using the agent is now supported. * bhyve: Support ``on_reboot`` and ``on_poweroff`` actions The bhyve driver now respects the domain's ``on_reboot`` and ``on_poweroff`` actions. * bhyve: Support populating SMBIOS fields Add support for populating the SMBIOS fields as defined by the ``<sysinfo type='smbios'>`` section of the domain's XML. * qemu: Add support for standalone VNC server Starting with this release, libvirt might spawn a standalone qemu-vnc process instead of QEMU's built-in VNC server, for enhanced security. * Improvements * Enable hyperv driver on RHEL The spec file now enables the Hyper-V driver when building on Red Hat Enterprise Linux. * remote: allow passing argv to the ext transport The ext transport not only allows spawning a process (via the ``command`` attribute), but as of this release also specifying additional arguments to it, via ``argv`` attribute. * Introduce ``VIR_CONNECT_GET_DOMAIN_CAPABILITIES_SUPPORTED_CPU_FEATURES`` flag Some CPU features may be enabled explicitly, but should not automatically become part of a host-model CPU and thus are not normally visible in domain capabilities. Users can now request such features to be shown in the host-model CPU in domain capabilities using the new flag. It is exposed as ``--supported-cpu-features`` option for ``virsh domcapabilities``. * Bug fixes * Ensure proper shutdown ordering of ``virtlogd`` and ``virtlockd`` The logging and locking helper daemons now shutdown after the daemon running the ``qemu`` hypervisor driver since their services may be needed to shutdown the VMs run by the qemu driver. * qemu: Record selected ``virtio`` video device model into the XML The ``qemu`` driver may depending on platform and installed QEMU modules pick one of two distinct virtio video device types for the primary device. The choice was not recorded in the XML and since the devices are incompatible it can cause failures on migration when the destination picks the wrong device. This version thus records the picked device both for running VMs on upgrade and for new devices to prevent this problem in the future. * bhyve: Guest agent related fixes A few bugs related to the guest agent communication are fixed, from not properly initializing an agent to crashing when the agent socket cannot be opened. * Fix domain capabilities on AMD CPUs QEMU 10.1 and newer does not automatically enable features from arch-capabilities MSR on AMD CPUs as they are specific for Intel CPUs and KVM is just emulating them on AMD. But advertising them on AMD CPUs can cause Windows guest OS to crash so they are hidden by default now. But the features are still supported and can be enabled explicitly, for example, when migrating existing domains. Libvirt now detects this scenario and properly shows the affected features as enabled in domain capabilities when requested by ``VIR_CONNECT_GET_DOMAIN_CAPABILITIES_SUPPORTED_CPU_FEATURES`` flag. * vmx: Properly show all 64 disks on a SCSI controller Due to an off-by-one error a last, 64th disk was not shown in a domain XML, which is now fixed. Enjoy. Jirka
