Network setup with Netplan and bridges

I'm having an issue where any bridge I create with netplan doesn't get an address.
The following starts my NIC and I get a DHCP address:
network:
version: 2
ethernets:
enp0s3:
addresses:
dhcp4: true
optional: true
This will start a bridge, and it will show up in "ip a" but won't retrieve an IP address from my DHCP server:
network:
version: 2
ethernets:
enp0s3:
addresses:
dhcp4: false
optional: true
bridges:
br0:
interfaces: [enp0s3]
dhcp4: true
optional: true
I feel like either I'm missing something really simple here, or this whole Netplan thing was/is terrible.

Are you trying this in virtual box... ? Having the same issues with a static IP address assigned to the bridge. You will find you can get to it from the console, but not externally. (ssh) etc. I think there is a bug in that the physical interface is not actually routing.

Yes, in VirtualBox. I'm seeing a few other reports of VBox issues with bridges as well, so maybe this is the culprit.
