[PATCH] conf: Restrict model type to enum members
by Adam Julis 08 Jan '25

08 Jan '25

Historically, we supported any string as the model type for network devices. This approach allowed us to stay up-to-date with QEMU's frequent introduction of new model types. However, this solution now causes more problems than benefits. A clearly nonsensical model name can pass validation but result in a QEMU internal error when the VM is started. This patch restricts model types to members of the 'virDomainNetModelType' enum. The enum has been extended to include all model types currently supported by QEMU. If QEMU introduces new models in the future, the enum must be updated to support them. Resolves: https://issues.redhat.com/browse/RHEL-72082 Signed-off-by: Adam Julis <ajulis(a)redhat.com> --- I'm not sure if the virtio-net-pci should be in this enum, since its not located in qemu repo in hw/net/ but in hw/virtio/. When I manually tested it, the qemu this option supported.

[RFC v3 PATCH 0/4] iproute2 bridge vlan support
by Leigh Brown 08 Jan '25

08 Jan '25

As requested by Laine, I have converted the code to use netlink rather than executing bridge vlan commands. I have also checked it compiles under FreeBSD. Description ----------- The iproute2 bridge command supports the capability for VLAN filtering that allows each interface connected to a standard linux bridge to be configured to use one or more VLANs. For simple setups, this capability is enough to allow virtual machines or containers to be put onto separate VLANs without creating multiple bridges and VLANs on the host. The first patch adds a new function virNetDevBridgeSetupVlans() that will, given a virNetDevVlan structure, execute the required bridge vlan commands to configure the given interface accordingly. The second patch updates the virNetDevBridgeAddPort() function to allow a virNetDevVlan parameter to be passed, and to call the virNetDevBridgeSetupVlans() function. The third patch updates the lxc and tap code to pass the virNetDevLan parameter from the configuration and to update the XML domain and network validation to permit the VLAN-related tags for standard bridges. The fourth patch updates documentation to match the new capability. Changes since v2 ---------------- - Convert to use netlink rather than executing bridge vlan commands. - Add unsupported on this platform error message on FreeBSD. Changes since v1 ---------------- - Fix bug in virNetDevSetupVlans where bridge port has no native vlan. - Update bridge network validation to permit vlan configuration. - Update documentation to match the functionality. - Tweak some of the commit descriptions for clarity. Usage example ------------- Configure the host with systemd-networkd as follows: /etc/systemd/network/br0.netdev (br0.network not shown) [NetDev] Name=br0 Kind=bridge MACAddress=xx:xx:xx:xx:xx:xx [Bridge] VLANFiltering=on /etc/systemd/network/eno1.network [Match] Name=eno1 [Network] Bridge=br0 [Link] MTUBytes=9000 [BridgeVLAN] VLAN=40 [BridgeVLAN] VLAN=60 Then add <vlan> tags into the lxc or qemu config: lxc interface definition: <interface type='bridge'> <mac address='xx:xx:xx:xx:xx:xx'/> <source bridge='br0'/> <vlan> <tag id='40'/> </vlan> </interface> qemu interface definition: <interface type='network'> <mac address='xx:xx:xx:xx:xx:xx'/> <source network='br0'/> <vlan> <tag id='60'/> </vlan> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x01' slot='0x00' function='0x0'/> </interface> Then, after starting them, you will see the following $ sudo bridge vlan port vlan-id eno1 1 PVID Egress Untagged 40 60 br0 1 PVID Egress Untagged vnet0 60 PVID Egress Untagged vnet1 40 PVID Egress Untagged Regards, Leigh Brown (4): util: add netlink bridge vlan filtering util: Add vlan support to virNetDevBridgeAddPort Enable vlan support for standard linux bridges docs: standard linux bridges now support vlans docs/formatdomain.rst | 37 +++++++++--------- docs/formatnetwork.rst | 45 +++++++++++----------- src/conf/domain_validate.c | 3 +- src/lxc/lxc_process.c | 3 +- src/network/bridge_driver.c | 13 ++++--- src/util/virnetdevbridge.c | 75 +++++++++++++++++++++++++++++++++++-- src/util/virnetdevbridge.h | 4 +- src/util/virnetdevtap.c | 2 +- src/util/virnetlink.c | 66 ++++++++++++++++++++++++++++++++ src/util/virnetlink.h | 7 ++++ 10 files changed, 202 insertions(+), 53 deletions(-) -- 2.39.5

[PATCH] qemu: allow migration of guest with mdev vGPU to VF vGPU
by Laine Stump 08 Jan '25

08 Jan '25

GPU vendors are moving away from using mdev to create virtual GPUs towards using SRIOV VFs that are vGPUs. In both cases, once created the vGPUs are assigned to guests via <hostdev> (i.e. VFIO device assignment), and inside the guest the devices look identical, but mdev vGPUs are located by QEMU/VFIO using a uuid, while VF vGPUs are located with a PCI address. So although we generally require the device on the source host to exactly match the device on the destination host, in the case of mdev-created vGPU vs. VF vGPU migration *can* potentially work, except that libvirt has a hard-coded check that prevents us from even trying. This patch loosens up that check so that we will allow attempts to migrate a guest from a source host that has mdev-created vGPUs to a destination host that has VF vGPUs (and vice versa). The expectation is that if this doesn't actually work then QEMU will fail and generate an error that we can report.

[PATCH v2 0/4] fix AppArmor policy restore for runtime rules
by Georgia Garcia 07 Jan '25

07 Jan '25

Some rules are generated dynamically during boot and added to the AppArmor policy. An example of that is macvtap devices that call the AppArmorSetFDLabel hook to add a rule for the tap device path. Since this information is dynamic, it is not available in the xml config, therefore whenever a "Restore" hook is called, the entire profile is regenerated by virt-aa-helper based only the information from the VM definition, so the dynamic/runtime information is lost. This patchset fixes that by storing these rules in a different file called libvirt-uuid.runtime_files, which is included by libvirt-uuid.files that already exists. It also includes other fixes like memory leaks, adoption of the GLib API in the apparmor files and a fix on the AppArmor policy that incorrectly applies apparmor policy syntax.

by Jiri Denemark 07 Jan '25

We are getting close to 11.0.0 release of libvirt. To aim for the release on Wednesday 15 Jan I suggest entering the freeze on Thursday 09 Jan and tagging RC2 on Monday 13 Jan. I hope this works for everyone. Jirka
