DAMN!
I forgot to DELETE my enp30s0f0 first before trying to assign it as a slave.
Thanks for the help Cole ;)

I've used this as a guide roughly:
https://www.happyassassin.net/2014/07/23/bridged-networking-for-libvirt-with-networkmanager-2014-fedora-21/
For example if you want to bridge enp30s0f0, do
- Stop the interface: nmcli con down enp30s0f0
- Open nm-connection-editor
- Set enp30s0f0 to _not_ 'connect automatically'
- Create a bridge, say named bridge0
- Under bridged connections, click add, select ethernet
- In the ethernet dialog, click Device, select enp30s0f0 MAC.
- Name the ethernet bridge0-enp30s0f0. Save everything and exit
- Save everything and exit. May need to explictly nmcli con up bridge0
- If you want to switch back to non-bridged mode, turn off bridge0 and
bridge0-enp30s0f0 autostart, and turn on enp30s0f0 autostart
Then have your VM use the bridge0 bridge
