One way that works is to specify eth0 in the container config file,
overriding the profile.
While you're at it you might wan to set host_name as well, so that the
veth device name on the host side stays the same.

Example:
devices:
  eth0:
    host_name: c1-0
    ipv4.address: 10.0.3.203
    name: eth0
    nictype: bridged
    parent: lxdbr0
    type: nic
