[tomp (Thomas Parrott)]

Weekly status for the week of the 21st March to the 27th March.

Introduction

This past week we have been focussing on finishing our roadmap items and preparing for the LXD 5.0 LTS release.

Additionally @stgraber has added a video on using Juju to operate a LXD cluster with Ceph, OVN and Grafana:

LXD

LXD now requires Go >= 1.18 to build due to upstream dependencies also requiring it.

New features:

• Block disk hotplug for VMs.

Improvements:

• Degraded network startup.

Bug fixes:

• Support --allow-inconsistent for cluster migrations.
• Allow disabling shiftfs indepedently of idmapped mounts (fixes shifting in the snap package).
• Add missing datasource field to Grafana dashboards.
• Fix regression in VM cdrom handling caused by work to add io_uring support.
• Remove old image storage volume record after image refresh.
• Clean up operations on LXD shutdown.

LXC

Improvements:

• Improve meson buid tests.
• Add fastpath routine on mkdir_p.

Distrobuilder

Improvements:

• Use available w11 and 2k22 drivers.

LXD Charm

Improvements:

• Adds support for core.dns_address.

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.
