-------------------------------------------
After restart vpc second time, same result as restart vpc first time.
> VPC: secondary public ip address (from diff Vlan range) doesn't get
> reprogrammed on the VR upon VPC/Network/VR resetart

> Key: CLOUDSTACK-6198
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6198
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Affects Versions: 4.3.0
> Reporter: Alena Prokharchyk
> Assignee: Alena Prokharchyk
> Priority: Blocker
> Fix For: 4.3.0
>
> Attachments: v1.png, v2.png, v3.png

>
> Regression bug.
> Steps to reproduce:
> 1. Create vpc and launch a vm in one tear.
> 2. vpc source ip address is from one subnet (ex: 10.147.52.1)
> 3. Acquire another public ip address from new public subnet.
> 4. create static nat on it to plug the nic on VR.
> 5. Now the VR has link local nic, guest nic, source nat ip nic and second
> public range nic.
> 6. Restart the vpc.
> 7. After restart there is no source nat nic.
> 8. If we restart vpc again observed that more nics are missed.
> I do observe the HUGE problem in 4.3 in
> VpcVirtualNetworkApplianceManager.java createVpcRouterNetworks() method. In
> 4.2 we used to store vm's nics in the ArrayList datastructure:
> List<Pair<NetworkVO, NicProfile>> networks = new ArrayList<Pair<NetworkVO,
> NicProfile>>(4);
> ArrayList does allow duplicates.
> Then in 4.3 the datastructure was changed to LinkedHashMap that doesn't allow
> duplicates:
> LinkedHashMap<Network, NicProfile> networks = new LinkedHashMap<Network,
> NicProfile>(4);
> To fix the problem, the datastructure has to be changed to
> LinkedHashMap<Network, List<NicProfile>>. It has to be changed all the way up
> to VirtualMachienManagerImpl where the nics are being passed to.
