    I'm running some tests to test the other functions for possible regression. Once it's

>            Reporter: Rohit Yadav

>             Fix For: 4.5.3, 4.6.0

>
> If a dedicated storage network is not provided in a zone, secondary storage VMs get two
management nics. This eats up an additional IP, the fix would be to allocate a storage nic
only when storage network is defined.
