------------------------------------------------------
Summary: [Multiple IPs Per Nic] This feature is not working well in case of networks with external devices after GC
Key: CLOUDSTACK-2045
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-2045
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Network Controller
Affects Versions: 4.2.0
Environment: commit bc3e184b7273da605177b0ac4ed7186f7fa36fbd
Reporter: venkata swamybabu budumuru
Priority: Critical
Fix For: 4.2.0
Steps to reproduce :
1. Have an advanced zone created with 1 Xen Cluster
2. create a network offering with SRX and Netscaler
mysql> select * from ntwk_offering_service_map where network_offering_id=14;

3. create a Network using the above offering
id: 210

4. deploy VM using the above network (for example : in my case it got 10.0.64.0/20 as CIDR)
5. acquire at least 2 secondary ips for the above nic
6. create some PF/static Nat rules
Below mentioned are the configured rules on secondary ips:
- PF & Firewall rule created on one secondary ip i.e. 10.0.65.59
- Static Nat & Firewall rule create on one more secondary ip i.e. 10.0.65.78

+----+-------------+-----------------+-----------------+---------------+
7. Stop the above VM and wait till network GC happens
Note : Make sure that "network.gc.interval" and "network.gc.wait" are set to some small value. in my case it is set to "10"
8. Make sure that above network is set to "Allocated" after GC
9. Deploy VM and verify everything is fine.
Observations :-
(i) After step:9, network got a new CIDR range allocated i.e. 10.0.32.0/20
(ii) Verified the table port_forwarding_rules which got automatically changed to the new CIDR but, that secondary ip doesn't exist anywhere.

Issue :
=====
While the secondary ips are still pointing to the OLD CIDR, network got a new CIDR after GC.
Enhancement/Improvement needs to be done here is :
==========================================
Either we need to persist the old CIDR or we need to change the secondary ips automatically fit into the new CIDR
Attaching the vmops.log and api.log
