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)



  • Aligned instance automatic scheduled snapshots and snapshot pruning with the recently changed custom volume snapshot tasks so that instance snapshots are pruned before new snapshots are created. This reduces the risks of a disk space shortage occurring.
  • Added support for triggering host-side device cleanup when a VM crashes or becomes non-responsive (at least when its QMP socket becomes non-functional).
  • Added support for vhost-net CPU offloading for VM NICs.
  • Added support for using the size storage pool property when creating an lvm thin-pool ontop of an existing volume group or physical device. Previously the thin-pool was created using 100% of the volume group free space, but this can now be overridden if needed.
  • Added support for copying running VMs (with understanding of both the default consistent mode and the optional --allow-inconsistent mode).
  • Updated the default storage pool loop file size logic to take into account free space on the host’s filesystem rather than overall disk size. If there is less than 5GiB space available the pool creation will be rejected without the user specifying a desired size explicitly. This is to try and avoid people getting into scenarios where they have created a sparse loop file backed storage pool that is larger than their actual free space and then encountering disk I/O errors when the parent filesystem runs out of space.

Bug fixes:

  • Fixed some issues with cluster healing, including adding support for instances in non-default projects, and attempting to start instances after healing.
  • Fixed cluster member rename so that the cluster member is aware its name has changed.
  • Fixed an issue where it was possible to import an instance backup over the top of an existing instance in certain scenarios. This is not a supported operation.
  • Fixed VM filesystem volumes incorrectly being created as ZVOL block volumes when zfs.block_mode was enabled. The VM filesystem volume is just used for config and its not appropriate/relevant for VMs to be influenced by the zfs.block_mode setting.

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.
