You're looking in the wrong section

https://linuxcontainers.org/lxd/docs/master/containers#type-nic

So something like this for veth on a bridge (on "lxc config edit
CONTAINER_NAME", in case you haven't figure it out):

devices:
  eth0:
    name: eth0
    host_name: c1-0
    nictype: bridged
    parent: lxdbr0
    type: nic

"parent" should be whatever the bridge is called on your host (lxd
creates lxdbr0 by default).
"host_name" is what the host side of the veth will be called (very
useful if you're doing host-side traffic monitoring).
