Weekly status for the week of 9th January to 15th January.
Introduction
The highlight of the past week was the release of LXD 5.10. This release continues the push to get the most performance out of our database and preparatory work for upcoming features, and includes some quality of life improvements and a good number of bugfixes.
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
Improvements:
- Added support for setting TX queue length on veth-based NIC devices. See
queue.tx.lengthsetting onbridged,p2pandroutedNIC types. - Reduced database transactions and queries used when listing cluster members and showing their config.
- Continued documentation restructuring and content improvements for instances, server and networks.
Bug fixes:
- Fixed a deadlock in
unix-charandunix-blockdevice source monitoring handler. - Fixes deletion of ephemeral VM instances on stop.
- Don’t allow manual targeting of a cluster member outside of the allowed groups of a restricted project. Previously the
restricted.cluster.groupsproject setting restricted which groups could be used when creating a new instance, but allowed any cluster member to be manually targeted. Now only members within at least one of the allowed groups can be manually targeted. - Fixed an issue where the snapshots listed in
lxc info <snapshot>were sorted alphabetically rather than by time (oldest first). Also fixed some cases in the API where snapshots were ordered by date only, and didn’t take into account the time part of the snapshot’s creation date.
LXC
Bug fixes:
- Allow overlay mount in
lxc-default-cgnsAppArmor profile. - Fix build error on sparc64 caused by using the gold linker.
LXCFS
Bug fixes:
- Handle NULL path in lxcfs_releasedir/lxcfs_release.
LXD Charm
Improvements:
- Add
grafana-dashboard-k8sinterface. - Add snap-config-lxcfs-debug parameter.
YouTube videos
