Do not remember why or if i enabled this in my previous but it is checked and the containers interface is named eth0@xyz where xyz is something Random that changes with every boot. It come as disabled on this new test setup with a different kind of lxd Network setup but still same kind of interface name. What exactly is this setting used for again? Code: root@mail:~# ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever 4: eth0@if5: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 00:16:3e:e9:1b:1e brd ff:ff:ff:ff:ff:ff link-netnsid 0 inet xx.xxx.xx.xxx/32 scope global eth0 valid_lft forever preferred_lft forever
