Weekly status #262


Weekly status for the week of the 15th August to the 21st August.

Introduction

The highlights of the past week were the releases of LXD 5.5 and LXD 5.0.1 LTS.

LXD 5.5 is the latest feature release which adds initial support for object storage and adds the concept of instance ready state.

LXD 5.0.1 LTS is the first bugfix release for LXD 5.0 series (which is supported until June 2027).

Also @stgraber has continued his series of videos about LXD storage drivers, this time looking at LVM:

LXD

All of the past weeks changes made it into the LXD 5.5 release.

New features:

Improvements:

  • Only use instant queries on Grafana piechart graphs as calculating old data isn’t needed.
  • Adds additional unique index to storage_volumes table to protect against duplicate volumes at the database layer. There was already a unique index that was doing this for local storage volumes, but was not effective for volumes on remote storage pools because the node_id field value was NULL meaning the current unique index didn’t take effect.
  • Include underlying error in message returned to user when failing to generate automatic IP address for new bridge networks.
  • Avoid using one-time prepared statements (that incur an additional network round trip time to setup) when loading and changing config rows. Also avoids unnecessary duplicated queries when loading daemon config at LXD start time.

Bug fixes:

  • Fixed an unreleased regression in LXD’s BGP integration that was preventing operation since the new hold time feature was merged.
  • Fixed an issue that was preventing instance copy/move/migration if the instance didn’t have the volatile.uuid setting. This is now automatically generated if needed.
  • Fixed an issue that was preventing OVN DNS names from working if the instance name had upper case characters in it. DNS names are now lower cased.
  • Fixed an issue related to storage pool deletion that was incorrectly using the requested project name when deleting remaining images before the pool was removed.
  • Fixed an issue that was preventing the use of the mtu setting on physical networks whose parent was set to an existing bridge when used as an ovn network uplink. This is now used to set the MTU of the veth interfaces connected to the bridge.
  • Fixed an issue when concurrently altering ACL rules when used with the xtables firewall driver that was causing races. Now uses the -w flag with iptables command for ACL rules.

LXC

Bug fixes:

  • Fixed docbook2x detection with meson.

YouTube videos
