Why are you using macvtap ("type='direct') to connect to a bridge
device? You should either use macvtap to connect directly to a physical
ethernet (e.g. eth0) *or* you should use a standard tap device
("type='bridge'") to connect to the bridge. Although it might work to
connect to a bridge using macvtap, I can't think of any reason you would
want to do it that way (and that may be the source of the error you're
seeing - since macvtap isn't intended to be used that way, that scenario
probably doesn't get much, if any, testing).
