Weekly status for the week of the 18th to the 24th July.

Introduction

The highlight of the past week was the release of LXD 5.4. This is the latest feature release and includes the new OVN load balancer feature. Please see the release notes and release video for more information.

Additionally @stgraber has produced a video covering LXD storage benchmarking:

LXD

The Ceph storage pool setting ceph.osd.force_reuse has been deprecated, as LXD expects a dedicated OSD pool, and as these are easily created in Ceph there is no known reason why LXD would need to share an OSD pool with another application.

Improvements:

  • Several DB query optimizations to improve instance start and launch speed.
  • Further improved our storage and cloud-init documentation.

Bug fixes:

  • Added support for volume.* storage pool settings to specifying the defaults for all storage volume settings. These settings will be consistently copied into any new volumes created.
  • Clarified that the --log-level flag on the lxc monitor command can only be used with the pretty formatting mode.
  • Fixed ParseFloat warnings when getting instance state of a stopped instance on an LVM thinpool.
  • Fixed handling of ethtool errors in the resources API.
  • Added handling of I/O errors from QEMU (caused when the disk is full).
  • Fixed possible hang when downloading an image if the remote server was not responding properly due to no HTTP header timeout being applied.
  • Fixed internal instance reference leak in VM driver monitor go routine.
  • Fixed DB generator to produce code compliant with our code style linters.
  • Removed some internal structs that were incorrectly added to our public API package.

Distrobuilder

Improvements:

  • Added Rocky Linux 9 support.

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.
