Configuring Virtulization network bridge on RHEL6

I'm trying to configure a KVM virtualization server using libvirt on RHEL6, I have the guest VMs configured and running, however am running into difficulties when bridging to the physical network. Unfortunately the physical network port has mac address filtering enabled, and therefore becomes disabled whenever the physical interface (eth3) is added to virbr0. How can I configure RHEL to hide the mac addresses of the vnetn virtual network devices?

You should be able to set up a static ip with a bridge for virtualisation fairly easily, you will find a short tutorial here It does assume you already have a standard eth0 connection working, but the steps are easy to follow and you should end up with a static ip and bridge ready to go.

The bridge is configured with an IP, however it exposes the Mac addresses of any virtual NICs connected to it. This means that the external switch blocks access to the port as it detects multiple devices attached. We're trying to configure the bridge to only present the Mac address of the external nic and to hide/mask the macs of the virtual devices.
