Port security only allowing 1 MAC

In my test environment I get everything working perfectly the way I want it. Running Cloudmin KVM instances over a bridged adapter. Then when it comes time to install at the data center I hit a brick wall. They have port security turned on which only allows one MAC address over the network port. Since I only have 2 interfaces I need to run several KVM instances (10 or more) with each assigned their on static public IP. I don’t have a range of IPs either. I was assigned specific ones.

Is there a way around this where I can assign each KVM instance it’s own IP but only use one MAC address?

I still have not gotten this to work. Is it common for data centers to block multiple MACs from the same network interface? Also shouldn’t I be able to add MACs to their switch for an exception?
