Weekly status #296

Weekly status for the week of 24th April to 30th April.


This past week some of the LXD team were in Prague for the Canonical roadmap sprint and this week the rest of the LXD team have joined them for the engineering sprint.

As well as planning for the next development cycle the team were also focused on reducing our bug backlog ready for the start of the next cycle.

Additionally @stgraber finished his video series on LXD instance devices by adding a summary video covering the nic top-level device type.

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)



  • Added qemu.conf to allowed files that can be accessed when retrieving logs.
  • Added oidc.* keys to bash completion.
  • Added support in the DB generation package to support marshalling/unmarshalling.

Bug fixes:

  • Fixed regression in snapshot pruning where snapshots that should have been deleted were not immediately removed.
  • Fixed lxc exec losing some output sometimes on highly loaded systems.
  • Fixed incorrect return type of GetStoragePoolVolumeNamesAllProjects in API client package to allow differentiating volumes of the same name in different projects.
  • Fixed lxc export so that if an export file name is not specified then the file created is named after the instance and uses the correct extension name based on the compression used.
  • Fixed panic in LXD when invalid migration success response was sent by client by handling a nil success message correctly.
  • Fixed regression in operation lock timeout for instance create by removing the automatic timeout of operation locks. As part of this the instance shutdown and instance restart tasks now use a default 10 minute timeout if not specified (rather than the previous indefinite timeout).
  • Fixed an issue with ZFS filesystem volumes when using block mode with ext4 that was restricting the root disk minimum size an instance could use when being created from an image. The fix was to disable resize2fs safety checks when creating instance volumes from an image volume that were smaller than the original image volume. By disabling safety checks the resize2fs command is able to shrink the volume to a smaller size, and it will still fail if the target size is genuinely too small. Disabling safety checks means that if the resize fails the volume will be left in an inconsistent state, but this does not matter when creating an instance as LXD will then delete the volume as part of the cleanup process.



  • Added the --with-post-files flag to the build-dir command. If set, it runs those post-files actions which don’t have a type filter set.

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.
