Weekly status for the week of the 25th to the 31st July.

Introduction

The highlights of the past week were the releases of LXC 5.0.1 LTS and LXCFS 5.0.1 LTS.

One thing to be aware of is that there is a known issue with LXCFS 5.0.1 when used with Fuse 3, please see https://github.com/lxc/lxcfs/issues/549.

On the LXD front we saw the completion of one of our roadmap items, the new Instance Ready state feature, which will allow application(s) running inside instances to report that the instance is ready for operation (as opposed to just started) which will then show up in the LXD API and lxc list output.

LXD

New features:

Improvements:

  • Automated spell checking has been added to our documentation CI checks and any issues with the previous documentation have been corrected.
  • Added the ability to specify a LXD remote address manually when using a token. This is useful in the scenario where all the server-side generated addresses are unreachable from the client due to SNAT being used. LXC will now ask for a manual LXD address if all addresses within the token are unreachable.
  • Completed the migration of our database logic to the new V2 generator.

Bug fixes:

  • Fixed a regression in LXD 5.4 that prevented the use of lvm.stripes.* setting on LVM storage pools that used a thin pool.
  • Fixed some incorrect URLs in the API SyncResponseLocation and lifecycle events.
  • Fixed a regression in LXD 5.4 that exposed a bug in Dqlite which restricted the amount of query bindings that could be used to 255. This issue only affected LXD installations where an instance list operation would generate >256 results. Until the Dqlite bug can be fixed we have worked around it by not using query bindings for the instance list query. This is still safe from SQL injection as the parameters being passed in are always integers.
  • Fixed a regression from LXD 5.3 that was preventing listing of instances when some instances had hundreds of snapshots. The queries for loading snapshot information have been made more efficient.
  • Fixed a crash in the resources API VPD parser.

LXC

New features:

  • Allow lxc-usernsexec to select which {g,u}id to switch to.

LXCFS

Bug fixes:

  • Fixed re-initialization issue when using fuse3.

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.
