Weekly status for the week of the 23rd May to the 29th May.

Introduction

The highlight of the past week was the release of LXD 5.2.

Please see the LXD release notes and live stream for more details:

We have also been focusing on reducing our issues backlog and our ongoing roadmap projects, including one of our roadmap items to add HTTP streaming support to the devlxd notification API (which was requested by the cloud-init team).

LXD

New features:

  • This adds http streaming support to the /1.0/events endpoint of devlxd. Clients can be notified about events without having to use websockets.

Improvements:

  • Ongoing work to refactor the VM QEMU config file to make the generation process clearer and more testable.
  • Added multi-hop support to the LXD BGP router exporter. This allows the upstream router to be more than 1 network hop away from the LXD server.
  • Database performance optimizations by reducing the amount of queries run.

Bug fixes:

  • Fixed an issue when copying instances and custom volumes to a different storage pool where the source volume config options were not used when mounting the volume on the source to send and thus if the source volume had config that was required for mounting (such as block.filesystem) then the migration couldn’t proceed.
  • Fixed an issue that prevented custom volume snapshot config from being copied when copying to a different storage pool.
  • Fixed an issue that was preventing --allow-inconsistent option from working when doing instance refresh on same storage pool.
  • Add mknod capability to the image unpack AppArmor profile as this is needed for the official Ubuntu images now.
  • Disable IPv6 on bridge networks when no ipv6.address setting is specified, to disable the link-local automatic address from being added to it.
  • Handle ethtool not supported errors in resources API.
  • Fixed an issue when copying profiles between projects.
  • Fixed an issue with forkfile idle cleanup when transferring a large number of files.

LXCFS

Bug fixes:

  • Correct file size of /sys/devices/system/cpu/online

Distrobuilder

Improvements:

  • Switch to use qcow2-v3 format for VM images (this is the default since QEMU 1.7).

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.
