The changes in this release include
New features:
- Ceph RBD can now be used as a LXD storage backend (including “lxd init” support).
- A new security.idmap.base key has been added.
This controls what base uid/gid to use on the host when using security.idmap.isolated. - Image downloads can now be interrupted.
- File transfers now support sending symlinks
- “lxc copy” and “lxc move” will now show progress information
- “lxc copy” and “lxc move” now support “relay” and “push” modes to go around firewalls and NAT
- Custom storage volumes can now have their size set and modified
- “lxc image import” now supports reading from a directory containing an unpacked image
- The “vlan” property can now be set on “physical” network interfaces (was just “macvlan”)
- It’s now possible to delete image volumes from a storage pool.
This allows removing a storage pool without having to remove the images from the image store. - The image metadata and template files can now be created and modified over the API.
This allows fine tuning of all image metadata prior to publishing. - Stateful snapshots can now be restored as a new container on a remote host.
