             Summary: [Multiple_IP_Ranges] Failure in adding additional network to a vm should delete the IP alias created 
                 Key: CLOUDSTACK-4083
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4083
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Management Server
    Affects Versions: 4.2.0
         Environment: Latest build from ACS 4.2 branch
            Reporter: Sanjeev N
            Priority: Critical
             Fix For: 4.2.0


Failure in adding additional network to a vm should delete the IP alias created if the additional network is a shared network and it has multiple subnets.

Steps to Reproduce:
=================
1.Bring up CS in advanced zone with vmware cluster
2.Create a guest vm with isolated network using default cent os template
3.Create a shared network with two subnets in the same vlan.
4.Exhaust all the ip addresses from the first subnet. 
5.Add this shared network to guest vm created above.

Adding shared network will create ip alias on the VR since the ip address that CS picks to assign to the vm will be from the second subnet in that shared network.

6. Since vmware-tools are not installed on guest vm adding additional network would fail.
Failure in adding additional nic will unplug the nic from vm and the nic will be in "Deallocating" state. As part of clean up the IP Alias got created at step5 should also be deleted and should be freed-up. Otherwise user will be charged for the IP usage even though not using it.

Please look for job-270 in the attached log file for the sequence of events .
