Weekly status #253


Weekly status for the week of the 13th June to the 19th June.

Introduction

While we continue our our larger roadmap items we have also added some efficiency and usability improvements to LXD and distrobuilder.

On the LXC side, LXC 5.0 LTS has been released, which is the third LXC LTS series. Please see the release notes for details.

Additionally @stgraber has added a video covering the network DNS zones feature in LXD:

LXD

Improvements:

  • Database query efficiency improvements - reduced loading unused data.
  • Instance device lifecycle cleanup - moves duplicated logic that existed in LXC and QEMU drivers into the common driver to simplify maintenance.
  • Allow copying/restoring instances (from migrations, backups and snapshots) that result in device conflicts with an existing instance. This allows the user to manually fix a conflicting instance’s config (using lxc config edit <instance>) before being allowed to start it, whereas before the instance creation process would have failed, meaning more low level manual fixes would be required (such as modifying a backup tarball contents or LXD snapshot database entry).
  • Adds support for SOA only response in DNS zones feature, and support returning full AXFR response when IXFR is requested (which appears to be better supported by external DNS servers than returning an error to the IXFR request).

Bug fixes:

  • Fix sysinfo syscall interception to use a stable source of instance boot time.
  • Fix potential crash in profiles check.
  • Use negotiated migration index header version on target side.

LXC

Bug fixes:

  • Fix bad strerror_r check in meson build.

Distrobuilder

Improvements:

  • Use multiple threads when possible for compressing.

Bug fixes:

  • Restore NetworkManager workaround after it was removed. Without the workaround, some containers only get an IPv4 address after a container reboot.
  • Mask systemd-firstboot service.
  • CentOS mirror updates.

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.
