Description

VR currently can not be LB service provider without requiring to be source nat service provider as well. It fails with error "Provider VirtualRouter doesn't support services combination: [Dns, Dhcp, Lb] ". This is a restriction made sense prior to network-as-a-service (earlier releases to 3.0). VR at that time was sole provider of all the services. Now with ability to choose different service providers for different services, its valid service and provider combination to have source nat service provided by different provider than VR, and LB service is provided by VR. Currently this combination is prevented while creating network offering.

This bug is to relax this restriction.

Its possible that, this may be non-trivial bug to fix. VR implicitly acquires a public IP for source nat and created public NIC on the VR by default. In the above mentioned case, only on acquiring IP for LB, Ip is associated with the VR so requiring that public interface is created on the VR.
