We have 10 running containers on our server. All of a sudden, all of them lost their internal ips (both IPv4 & IPv6) at some point today. Not sure when exactly, but they were running OK, with IPs assigned, yesterday last time I’ve checked. Noone was connected to the server nor making any configuration changes meanwhile.
I’ve restarted the daemon itself now with
sudo systemctl reload snap.lxd.daemon , and after couple of minutes they all got back their IPs assigned. I cannot say for sure if the restart fixed it, but I hope it did.
By looking at lxd.log I did not find anything suspicious there.
Let me know if you need some logs or config extracted so you can look into it. What might have caused this behaviour?
