Method of identifying destination in a virtual environment

A computing system, comprising:

• a processor;
• and
• a memory containing a virtualization program configured provide a virtual switch for a plurality of virtual machine instances on the computing system, the program, when executed on the processer, performs an operation comprising:
• assigning a port profile to a first port group on the virtual switch executing on the computing system, wherein the computing system hosts a plurality of virtual machine instances, and wherein the port profile includes a network traffic destination rule;
• connecting a virtual network interface on each of the virtual machine instance to a port in the first port group;
• and
• forwarding, by the virtual switch, network traffic addressed to one of the virtual network interfaces based on the traffic destination rule.

A computer-readable storage medium, containing a virtual switch program, which, when executed on a processor, performs an operation, comprising:

• assigning a port profile to a first port group on a virtual switch executing on a computer server hosting a plurality of virtual machine instances, wherein the port profile includes a network traffic destination rule;
• connecting a virtual network interface on each of the virtual machine instance to a port in the first port group;
• and
• forwarding network traffic addressed to one of the virtual network interfaces based on the traffic destination rule.
