LXD 0.22 release announcement

10th of November 2015

The main changes for this release are

  • Freeze containers before killing them (helps with fork bombs)
  • Configurable image compression algorithm (also supports no compression)
  • Support using an HTTP proxy when downloading a remote image
  • Initial implementation of the events interface and minimal client for it (lxc monitor)


  • Don't remove the main LXD socket when starting a second daemon
  • On failure to add a remote, cleanup the cached certificate
  • LXD no longer requires a client certificate to talk to public endpoints
  • Better error and debug messages for checkpoint/restore and container startup
  • Fixed a race condition during container startup
  • Update the busybox test image to avoid an occasional hang
  • lvm-setup: Update to work on older Ubuntu releases
  • Fix extraction of bz2 compressed images
  • Fix a number of fd leaks
  • Fix shmount handling to avoid creating an extra mount every time LXD starts
  • lxd-images: Fallback to the daily stream if an image can't be found in the releases stream
  • Fix a uid/gid mapping issue on container copy
  • Fix a LXD hang on invalid LXC configuration key

Upgrade notes

This LXD version corrects a problem in the implementation of the images API,
as a result, some actions against older servers or using older clients may fail.
