Weekly status for the week of the 27th of September to the 3rd of October.

Introduction

The highlight of the past week was the release of LXD 4.19 which includes the new Prometheus metrics exporter feature from our roadmap. For more information please see the release notes and the release video.

LXD

This past week we have added support custom block volume export and container core scheduling. There has also been a focus on improving the clustering reliability and LXD shutdown sequence to fix some intermittent issues seen in our test suite.

New features:

  • Added support for exporting custom block volumes.
  • Added core scheduling support for containers - this is enabled by default if both the kernel and liblxc support it.

Improvements:

  • LXD server shutdown improvements to handle cluster role transition earlier and make the /internal/shutdown API endpoint synchronous so that lxd shutdown doesn’t depend on the global database being available.
  • Disable large decrementor support on ppc64le to support more machine types.
  • Create directories when using lxc file pull with the -p option.

Bug fixes:

  • Fix filesystem volume export for cephfs custom volumes (and added tests).
  • Fix metrics IO stats on cgroup2 systems.
  • Add instance type to metrics.
  • Don’t listen on IPv6 wildcard :: when specifying 0.0.0.0 as the API listen address.
  • Handle :<port> format for API listen address.
  • Don’t log an “In Use” error when unmounting a custom volume that is in use with another instance.
  • Fix cluster remove leader issue that was calling dqlite twice.

LXC

New features:

  • Added core scheduling support.

Improvements:

  • Several improvements to the build approach.

Distrobuilder

Bug fixes:

  • Handle merged /usr in debootstrap.
  • Shellcheck fixes.

Dqlite (RAFT library)

Improvements:

  • Extend tracing feature.

Bug fixes:

  • Leader removal would sometimes trigger an assertion.

Dqlite (database)

Improvements:

  • Added timestamp to trace.

Dqlite (Go bindings)

Improvements:

  • Added benchmark tool.

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.
