Weekly status for the week of the 24th to the 30th of January.
Introduction
This week saw two of the features lined up for LXD 5.0 LTS get merged, the support for custom DNS records in network zones and the support for retrieving ACL logs.
On top of that, we got a couple of additional configuration options for those using LXD on ZFS and a variety of bugfixes and improvements to documentation, dqlite and the LXD charm.
LXD
New features:
- Custom DNS records in network zones
- Network ACL logs
- ZFS reservation setting
- ZFS block size setting
Additionally, LXD now performs a bit better for Windows VM guests by emulating HyperV flags.
Dqlite
Improved buildability on Windows (still work in progress), fixed test issues on 32bit architectures and cleaned up an unused mutex.
LXD charm
Add a complete example bundle (LXD + OVN + Ceph) and improved the integration with OVN (automatic configuration of the connection string in LXD).
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.
