Is it possible to use DHCP to configure the bridge device itself using
that, similar to what's described in [1] ? And have guest's DHCP
requests forwarded across the bridge ? The docs only talk about static
IP assignments for the bridge device.
That configuration is what I'm calling a "shared physical interface".
I wouldn't be surprised if NetworkManager could only be used for this
exact configuration rather than any possible variation of bridge
configuration.
Which is why I'm suggesting just using a "shared" property on a
interface - this property would imply the creation of a bridge.
