> Failure in deleting guest IP range should mark ip alias state in nic_ip_alias table to
Revoked 
> Steps to Reproduce:
> =================
> 1.Bring up CS in basic zone with xenserver 6.1
> 2.Exhaust all the guest IP ranges from the primary IP range added during zone creation
> 3.Add another guest IP range in new CIDR
> 4.Deploy guest vm
> 5.Set expunge interval to a small value say 60 secs, and restart management server
> 6.Destroy the guest vm deployed at step4
> 7.After vm expunge, delete the guest IP range added at step3
> Expected Result:
> =============
> In case of successful deletion of the guest IP range , ip alias created on VR should
be deleted and the entry from nic_ip_alias table should be removed.
> Actual Result:
> ============
> Due to bug CLOUDSTACK-2621, IP range deletion failed and alias IP address remained in
allocated state in user_ip_address table but ip alias was removed from the backend(from the
VR).
> nic ip alias state shows active in the DB.
> Impact:
> ======
> Since the deletion failed, if the user wants to use the ip range and tries to deploy
vm using this guest IP range, guest vms does not get the IP address since VR does not have
ip alias to server dhcp request in this guest range.
> CS does not try to recreate ip alias on VR since nic_ip_alias table shows the state as
active.
