You're welcome.

I've never used virt-manager but I assume that it functions like
virt-install or that it uses virt-install under the gui.

If that's the case, it won't use predefined tap devices, slaved to a
bridge or not. It'll create vnetX tap devices and add them to a bridge
on the fly. But if you want to use tapX tap devices rather than vnetX
ones, you can edit the xml to set that up.
