Weekly status for the week of the 7th March to the 13th March.

Introduction

The highlights of the past week were the releases of LXD 4.24 and LXCFS 5.0.0 LTS. The LXD release is the last feature release before we start the LXD 5.0 LTS series, and LXCFS is the first in its new 5.0 LTS series.

The release video of LXD 4.24 can be seen here:

Additionally @stgraber has added a video covering using the new multi-user feature of LXD, which can be useful when deploying LXD to desktops in an enterprise environment:

LXD

Improvements:

  • Added a --listen flag to the lxc file mount command to allow forcing the use of the SSH SFTP listener (rather than trying to use sshfs) and allowing to specify which IP and port to setup the listener on.
  • Switched VM TPM device to CRB mode.
  • Added restricted.containers.interception to projects to prevent the use of potentially unsafe interception features in restricted projects.
  • Allow unauthenticated access to metrics API endpoint.
  • Set spawn=allow option in QEMU for VMs as part of working toward support for QEMU 5.2.
  • The lxc storage volume info command now returns an empty EXPIRES AT field value if no expiry set.
  • Added last-modified to the file API.

Bug fixes:

  • Fix heartbeat hang during cluster upgrade by adding a websocket handshake timeout to the event client.
  • Fixed some issues with the new AppArmor profile for image archive unpacking when using custom volumes for images.
  • Fixed a recent regression in VM live migration.
  • Fixed a recent regression in VM disk shares.
  • Allow ipv{n}.address=none to be set on bridged NICs that connect to managed networks to allow filtering all protocol traffic.
  • Fix disk usage in the Grafana dashboard.
  • Disable idmapped mount support if environment variable LXD_SHIFTFS_DISABLE=true.
  • Fix image archive unpack ownership issue by passing --numeric-owner to the tar command.

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.
