Weekly status for the week of the 17th to the 23rd of January.
Introduction
This week was a bit of a slower week due to part of the LXD team attending a (virtual) company quarterly meeting. This was however a good opportunity to go through some of the issue and pull request backlog which led to quite a few smaller features being included this week.
LXD
New features:
- Support for VLAN ranges in
vlan.tagged - Server side filtering of storage volumes
- OVN network state
- Support for image requirements
- Option to disable ZFS pool export on shutdown
On top of those, LXD also saw a number of fixes for a database regression caused by LXD 4.22, some documentation improvements and fixes for live-migration on evacuation.
LXC
On the LXC front, we merged a fix for lxc-checkconfig on newer kernels and reworked some of the cgroup logic.
Distrobuilder
Fixed an issue with newer systemd and units making use of ProcSubset.
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.
