I am using libvrt for the first time. Im building a KVM for multiple
Virtual OS instances.

The problem i have is with your official documentation for Virtual

The following is wrong:

The default mode is BRIDGE + NAT.

Optional mode is ROUTING.

It should be:

The default mode is ROUTING + NAT.

Optional mode is BRIDGE.

As far as i know a bridge operates on the Layer2.

IP and NAT operate on the Layer3.

NAT can not operate on the L2.

Please tell me that im wrong and explain how am i wrong.

Best Regards
