venet is a special network device that is designed to be managed from
the HN but not from inside the CT. In case you want to be able to tune
network interface from inside the CT, veth is a right choice. Unfortunately,
in your case it's impossible to realize what you want to do because it's
prohibited to create bridges inside the CTs.
