- Update to LXD 4.24. The full upstream changelog is available from:
https://discuss.linuxcontainers.org/t/lxd-4-24-has-been-released/13550
boo#1199215
This is the last release before LXD 5.0 (which does not support the Leap 15.3
kernel -- LXD 5.0 requires kernel 5.4 or newer). Thus this will be the last
LXD release for Leap 15.3.
+ lxc file mount and new files API
+ Cluster event hub role
* Reworked lxc storage volume info
+ AppArmor profiles for image extractors
+ Grafana dashboard
+ Degraded startup (missing disk)
+ restricted.containers.interception project option
+ core.metrics_authentication server option
+ Network interface name and MTU in virtual machines
+ I/O uring support for VM storage
+ ipv4.neighbor_probe and ipv6.neighbor_probe NIC options
