---------------------------------------

             Summary: provide option to turn-off automatic public IP association for each
VM when using EIP service.
                 Key: CLOUDSTACK-265
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-265
             Project: CloudStack
          Issue Type: Improvement
          Components: Network Controller
    Affects Versions: 4.0.0, 4.1.0
            Reporter: Murali Reddy
            Assignee: Murali Reddy
             Fix For: 4.1.0


Current EIP in CloudStack has below semantics.

   - When a user VM is deployed, a public ip is automatically acquired. This IP is owned by
the vm's        account and is marked as 'system' in the db.

   - When the user VM starts, static NAT is provisioned on the static NAT provider between
the public ip and the guest ip of the vm.

Since public IP's can be scarce resource is some deployments, its not desirable to allocate
a public IP by default. This bug is to provide the flexibility for cloud providers to enable/disable
the ability to automatically allocate public IP.
