Weekly status for the week of 10th April to 16th April.
Introduction
The highlight of the past week was the release of LXD 5.13! This release includes several new features from our roadmap including adding new virtual machine and OVN network functionality, new authentication options and improved storage pool management.
Please see the release notes and release video for more details:

Job openings
Canonical Ltd. strengthens its investment into LXD and is looking at building multiple squads under the technical leadership of @stgraber.
As such, we are looking for first line managers (highly technical) and individual contributors to grow the team and pursue our efforts around scalability and clustering.
All positions are 100% remote with some travel for internal events and conferences.
For more info please see LXD related openings at Canonical Ltd (2022-2023)
LXD
All of the functional changes from last week were included in LXD 5.13.
New features:
- Added nested VLAN
ovnNICs. This provides the ability to get up to 4096 additionalovnNICs into an instance without having to use additional PCI addresses/veth pairs for additional virtual NICs. See LXD 5.13 has been released - Added support for OpenID Connect authentication. As part of a push to provide a more industry standard solution to authentication and authorization in LXD, we’ve begun the work by adding support for OpenID Connect for authentication. See LXD 5.13 has been released
- Added support for VDPA acceleration when using SR-IOV with
ovnNICs. See LXD 5.13 has been released - Added Layer 3 only support to
ovnnetworks. See LXD 5.13 has been released
Improvements:
- Added an example in the help text of
lxc network create. - Clarify the cluster member name options in
lxc cluster add. - New VM volumes on ZFS storage pools now set the ZFS
primarycacheandsecondarycacheoptions tometadata. This is to avoid double caching the VM filesystem activity both inside the guest’s filesystem cache and in the host’s ARC cache. - Added support for compression in metrics API.
Bug fixes:
- Fixed regression that was preventing ZFS block volume devices from being deactivated on instance stop.
- Fixed live migration cleanup on premature error to avoid leaving blocked QEMU processes running on the target host.
- Fixed virtual function and representor port clean up on instance stop when using
ovnNICs withsriov=acceleration. - Fixed metric duplication issue in metrics API.
LXC
Bug fixes:
- Fixed
setproctitle()'s parsing of/proc/pid/statto make it safe.
LXCFS
Bug fixes:
- Resolve cpu cgroup path separately from cpuset as the cgroup path is different in kubernetes with containerd runtime.
LXD Charm
Improvements:
- Add metrics-endpoint interface to integrate with prometheus-k8s charm.
YouTube videos
The LXD team is running a YouTube channel with live streams covering LXD releases and weekly videos on different aspects of LXD. You may want to give it a watch and/or subscribe for more content in the coming weeks.
