I don’t know exactly when this happened but I suspect a recent auto snap LXD upgrade.
Anyway, I noticed that one of my containers was lacking an IP address on one of its network interfaces. Investigating further I noticed that the netplan file that cloud-init generates was missing that interface.
I added it in manually and noticed syslog was getting errors:
dhcpcd: eth1: adding default route
dhcpcd: if_route (ADD): Invalid argument
The broken interface is declared as macvlan in the container’s config. Only the bridged interface is coming up and working. I have other containers with only macvlan interfaces and none of them come up.
I’m running LXD 5.3. I’ve tried to downgrade LXD to 5.2/stable in snap but it won’t run the old one after I switch channels.
Can anyone help please, with
a) reverting to an older LXD to see if I can get my production system working again
b) debugging this issue
