Removed the hard coded MAC OUI in the code and instead fetches the OUI from settings.py
If independent instances of WebVirtCloud (or any libvirt) exists on the same subnet and VMs are configured to use a bridge interface, this could lead to duplicate MACs on the same subnet (low probability, but still possible).
This change gives the user a choice to define an OUI.
It is a standart Kvm ethernet MAC prefix. It should not be problem. This prefix defines that Ethernet is a Kvm vm Ethernet. But your suggestion does not Break anything.
