[lxc-users] Converting network from LXC to LXD

Because netmask is taken from bridge configuration. (Presumable.)

You don't need to.

Gateway is served via DHCP from the bridge.

> $ lxc config device set mycontainer eth0 ipv4.gateway 192.168.21.1
> Error: Invalid devices: Invalid device option: ipv4.gateway

> I can manually add them afterwards, i.e.

> $ lxc exec mycontainer ip address add 192.168.21.2/24 dev eth0
> $ lxc exec mycontainer ip route add default via 192.168.21.1 dev eth0

You're missing the purpose.
LXD is not supposed to be so tightly controlled on per container basis.
LXD containers supposed to be deployed en masse, with minimal individual
configuration.
