Choonho Son created CLOUDSTACK-512:
--------------------------------------

             Summary: remove hostname in a virtual router's DNS service, after expunging VM
                 Key: CLOUDSTACK-512
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-512
             Project: CloudStack
          Issue Type: Bug
          Components: Network Controller
    Affects Versions: pre-4.0.0
            Reporter: Choonho Son


The domain name of guest VM is not deleted, even though the guest VM is expunged.

Scenario:
1. Deploy VirtualMachine with hostname "head1"
2. Delete "head1" VirtualMachine
3. Deploy VirtualMachine with hostname "head1"
4. Delete "head1" VirtualMachine
...

After repeating this process, ask ip address of "head1"
nslookup head1

The result looks like

[root@repo src-conf]# nslookup head1
Server:         172.27.0.1
Address:        172.27.0.1#53

Name:   head1.cs82epc-dev.ucloud.com
Address: 172.27.114.224
Name:   head1.cs82epc-dev.ucloud.com
Address: 172.27.110.235
Name:   head1.cs82epc-dev.ucloud.com
Address: 172.27.182.109
Name:   head1.cs82epc-dev.ucloud.com
Address: 172.27.76.251
Name:   head1.cs82epc-dev.ucloud.com
Address: 172.27.196.212
Name:   head1.cs82epc-dev.ucloud.com
Address: 172.27.116.53
Name:   head1.cs82epc-dev.ucloud.com
Address: 172.27.35.214
Name:   head1.cs82epc-dev.ucloud.com
Address: 172.27.248.170
Name:   head1.cs82epc-dev.ucloud.com
Address: 172.27.33.158
Name:   head1.cs82epc-dev.ucloud.com
Address: 172.27.116.64
Name:   head1.cs82epc-dev.ucloud.com
Address: 172.27.71.218
Name:   head1.cs82epc-dev.ucloud.com
Address: 172.27.65.181

Problem:
- Other guest VM cannot connect "head1" VM using domain name,
- Because only one IP address is valid.
