Hello, hope it works in German. Need some help. My problem: Windows 10 won't boot anymore, automatic repair doesn't work either. Is there a way to repair Win10 and how? Best regards Gilbert Adam

[PATCH] rpm: fix setting of VIR_TEST_DEBUG
by Daniel P. Berrangé 05 Jun '24

05 Jun '24

The %meson_test macro expands to have a newline at the start, so rather than expanding to VIR_TEST_DEBUG=1 meson test .... we get VIR_TEST_DEBUG=1 meson test .... which has no effect, since VIR_TEST_DEBUG isn't exported.

[PATCH] interface: fix udev reference leak with invalid flags
by Daniel P. Berrangé 05 Jun '24

The udevInterfaceGetXMLDesc method takes a reference on the udev driver as its first action. If the virCheckFlags() condition fails, however, this reference is never released.

Release of libvirt-10.4.0
by Jiri Denemark 03 Jun '24

03 Jun '24

The 10.4.0 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 * qemu: Support for ras feature for virt machine type It is now possible to set on/off ``ras`` feature in the domain XML for virt (Arm) machine type as ``<ras state='on'/>``. * SSH proxy for VM Libvirt now installs a binary helper that allows connecting to QEMU domains via SSH using the following scheme: ``ssh user@qemu/virtualMachine``. * qemu: Support for ``virtio`` sound model Sound devices can now be configured to use the virtio model with ``<sound model='virtio'/>``. This model is available from QEMU 8.2.0 onwards. * network: use nftables to setup virtual network firewall rules The network driver can now use nftables rules for the virtual network firewalls, rather than iptables. With the standard build options, nftables is preferred over iptables (with fallback to iptables if nftables isn't installed), but this can be modified at build time, or at runtime via the firewall_backend setting in network.conf. (NB: the nwfilter driver still uses ebtables/iptables). * Improvements * qemu: add zstd to supported compression formats Extend the list of supported formats of QEMU save image by adding zstd compression. * qemu: Implement support for hotplugging evdev input devices As of this release, hotplug and hotunplug of evdev ``<input/>`` devices is supported. * Bug fixes * virsh/virt-admin: Fix ``--help`` option for all commands A bug introduced in `v10.3.0 (2024-05-02)`_ caused that the attempt to print help for any command by using the ``--help`` option in ``virsh`` and ``virt-admin`` would print:: $ virsh list --help error: command 'list' doesn't support option --help instead of the help output. A workaround for the affected version is to use the help command:: $ virsh help list * qemu: Fix ``virsh save`` and migration when storage in question is root_squashed NFS Attempting to save a VM to a root_squash NFS mount or migrating with disks hosted on such mount could, in some scenarios, result in error stating:: 'Unknown error 255' The bug was introduced in `v10.1.0 (2024-03-01)`_. * qemu: Don't set affinity for isolcpus unless explicitly requested When starting a domain, by default libvirt sets affinity of QEMU process to all online CPUs. This also included isolated CPUs (``isolcpus=``) which is wrong. As of this release, isolated CPUs are left untouched, unless explicitly configured in domain XML. * qemu_hotplug: Properly assign USB address to hotplugged usb-net device Previously, the network device hotplug logic would try to ensure only CCW or PCI addresses. With recent support for the usb-net model, USB addresses for usb-net network devices are assigned automatically. * qemu: Fix hotplug of ``virtiofs`` filesystem device with ``<boot order=`` set The bug was introduced in `v10.3.0 (2024-05-02)`_ when attempting to reject unsupported configurations. During hotplug the addresses are assigned after validation and thus errorneously reject valid configs. Enjoy. Jirka
