Weekly status for the week of the 5th of July to the 11th of July.

Introduction

The highlight of the past week was the release of LXD 4.16, please see the release notes for more details.

In preparation for that release, quite a few improvements to the lifecycle API were landed. There was also a round of improvement around race conditions in SR-IOV device handling as well as improving VM startup.

Additionally, there was some preparation work for the upcoming LTS bugfix releases which are due later this week.

The LXD team is hiring

The LXD team at Canonical is currently looking for a Go software engineer to join our distributed team of engineers. We’re looking for candidates anywhere in Europe or the Americas!

All LXD positions are 100% remote with some travel for internal events and conferences.

LXD

New features:

  • When using a managed bridge network with DNS enabled, LXD now adds a DNS record for the host/gateway IP under the name _gateway.<domain>, e.g. _gateway.lxd.
  • Supported storage drivers are now returned in lxc info output, and used for lxd init.

Improvements:

  • Improved lifecycle events.
  • Duplicate NIC ipv{n}.address and MAC setting detection.
  • Records last used VSOCK ID when starting VMs (which will allow lxd-agent to work in the forthcoming recovery feature when a running VM is recovered).

Bug fixes:

  • Instance related persistent warnings are now removed when an instance is deleted.
  • Fix SR-IOV NIC race condition when selecting a free virtual function when starting multiple instances concurrently.

Youtube channel

We’ve started a Youtube channel with live streams covering LXD releases and its use in the wider ecosystem.

You may want to give it a watch and/or subscribe for more content in the coming weeks.
