    LGTM - Deployed a full stack Nicira environment: 3 controllers, a manager, a service node
and 2 KVM hypervisors, all inside my development VM:
    # virsh list
     Id    Name                           State
     42    nsxmgr1                        running
     43    nsxcon1                        running
     44    nsxsvc1                        running
     48    kvm1                           running
     49    nsxcon2                        running
     50    nsxcon3                        running
     52    kvm2                           running
     54    cs1                            running
    Then I ran the Marvin tests:
    # nosetests --with-marvin --marvin-config=/data/shared/marvin/mct-zone1-kvm1-NVP.cfg -s
-a tags=advanced,required_hardware=true test/integration/smoke/
    test_01_nicira_controller (integration.smoke.test_nicira_controller.TestNiciraContoller)
... === TestName: test_01_nicira_controller | Status : SUCCESS ===
    Nicira clusters will redirect clients (in this case ACS) to the master node. ... === TestName:
test_02_nicira_controller_redirect | Status : SUCCESS ===
    Ran 2 tests in 766.910s
    BTW: The Marvin data center config file is available here:

> When setup in a cluster, NSX controllers will redirect calls to the cluster master. However,
the NiciraNvp plugin does not handle those redirects correctly. The underlying HTTP client
will transparently redirect calls, but the plugin will aways override the target host to the
initial value.
> The underlying HTTP library being used at the moment is Apache HTTP Commons, which has
been superseded by Apache HTTP Components which introduces a new architecture. This library
should be upgraded to the new architecture since this will make it easier to transparently
handle redirects,
