Hi Paul,
tbh I'm not exactly sure what you are trying to do overall. But from your
script it seems to me that you are trying to create an OVS port so a libvirt
instance outside of Nova control can use it. And you don't need the linux
bridge for security group iptables.
AFAIK the tap must be created first using the ip command. Then when 'ovs-vsctl
add-port' is called with the same name as the tap device for the port name, the
tap device will be enslaved properly in the OVS bridge.

Regards, Darragh.
