Chandan Purushothama created CLOUDSTACK-152:
-----------------------------------------------
Summary: Routes on the User VM are programmed incorrectly on a VM
present on both an Isolated and Shared Guest Networks
Key: CLOUDSTACK-152
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-152
Project: CloudStack
Issue Type: Bug
Components: Management Server
Affects Versions: pre-4.0.0
Reporter: Chandan Purushothama
Fix For: pre-4.0.0
==================
Steps to Reproduce:
==================
1. As the Admin of ROOT domain, Create a shared guest network using the
DefaultNetworkOfferingforSharedNetworks.
2. Login as a Regular User. Create an isolated guest network using the
"DefaultNetworkOfferingwithSourceNATService"
3. Register a CentOS6.3_x86_64 ISO
4. Deploy a VM on the Isolated and Shared Guest Network using the ISO. Make
sure that the Isolated Guest Network is chosen as the default Guest Network.
5. View the VM's Console. Observe that the only IP Address present on the VM is
the loopback address.
6. Edit the two ifcfg-ethx files present under /etc/sysconfig/network-scripts/.
Set the ONBOOT parameter to yes.
7. Reboot the VM or restart the network service.
8. Observe the routes on the VM after the Reboot.

**Observe that except the second and the third route all the remaining routes
are wrong. Notice that 10.1.1.48 is on eth0 while 10.223.137.78 is on eth1**
