Weekly status for the week of the 22nd to 28th of November.
Introduction
Last week LXD gained first-class cloud-init support as well as improvements to custom storage volume copy and move features, along with some fixes for OVN networks.
LXD
@stgraber has added a new video on using Ceph with LXD:

New features:
- First class cloud-init support using the new instance config keys:
cloud-init.vendor-data,cloud-init.user-data, andcloud-init.network-config. For more information please see [LXD] First class cloud-init support. - Custom storage volumes can now be copied/moved to a particular target cluster member using the
--destination-targetflag. It is also possible to specify the source cluster member that has the custom volume using the--targetflag.
Improvements:
- Surface instance unmount errors during instance stop sequence, and allow more time for ZFS unmount process to succeed (as sometimes it can take the ZFS subsystem a while to flush the data back to the storage device).
Bug fixes:
- Fixes using project
restricted.devices.disk.pathswithdiskdevices when running LXD via the SNAP package. - Ensure OVN networks only consider compatible networks for use as uplink candidate. Avoids needing to manually specify the uplink network when creating a new OVN network if there is only one compatible uplink candidate network available.
- Fix OVN peer routing bug when setting up instance NIC routes on peer networks. These were previously being directed to the incorrect logical port.
- Moves the readonly VM config drive bind-mount out of the config drive path itself and into the devices path. This is to fix an issue that was preventing VM snapshots taken on
dirstorage pools from being started due to incorrectly copying the bind-mount contents into the snapshot. - Fix the DB generator to support sql.NullTime fields.
- Remove the need for cgo in the
shared/termiospackage which enables the use of the Go race detector.
Distrobuilder
Bug fixes:
- Cloud-init fixes.
- Allow cancelling downloads.
- Fix downloads with multiple hashes.
Dqlite (RAFT library)
Bug fixes:
- Fixes issue where candidate could count the vote in a pre-vote RequestVoteResult RPC as a real vote.
- Fix memory leak when crc check failed.
- Add original error code to uv_writer errmsg.
LXD Charm
Improvements:
- Don’t warn on upgrade for
lxd-listen-*keys.
