[PATCH v3 0/2] Fix forward type=hostdev nets for apparmor
by Tim Small 09 Jun '25

09 Jun '25

Fixes a bug whereby apparmor permissions aren't granted to allow a PCI SR-IOV virtual function to be used in a kvm guest when the VF is defined via a forward type='hostdev' network (as per the 'hostdev' option documented here: https://libvirt.org/formatnetwork.html#connectivity ). Downstream bug here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=993856 qemu accesses these PCI virtual functions using the vfio API, so no additional permissions to access to the PCI device resources etc. via /sys/devices/pci[...]/resource et al. are necessary. This is a resend with fixed From in body for the patch emails, and change notes in patch emails. Thanks, Tim.

[PATCH v5 0/3] Fix virtio console port assignment issue

Changelog: --- v5: - Added xml tests to tests/qemuxmlconfdata - Fixed virito -> virtio typo in commit message --- v4: - Update commit messages --- v3: - Added Reviewed-By - Included CI Results Link --- v2: - Split patch into two commits - Added fixes tag --- This libvirt patch series does the following: 1. fixes an issue with virtio console device port auto assignment on vioserial buses 2. updates console port reservation comment and changes the allowZero variable to allowPortZero for clarity 3. Adds tests for virtio console on the vioserial bus Currently in libvirt, a virtio console device cannot be auto assigned a port number greater than zero on a vioserial bus. This leads to port collision errors when adding more than 1 virtio console device on a single vioserial bus. After applying this patch, one can add multiple console ports under a single vioserial bus.
