Really? I use it that way with KVM. Add a bridge device br0 with
bridge-utils and add to this bridge my "real" ethernet device. All my
KVM guests got this br0 device and everything is fine. Ok, LXC/LXD would
add another device in a different namespace to this bridge, but this
shouldn't be a problem. But maybe I'm wrong...

But anyway, using libvirt with the virbr0 which libvirt provides is
maybe the easier solution (if my solutions works with lxc, I never
tested this (shame on me)).

Thomas.
