Hi Somesh, I did a bit of tweakng to understand the issue.
I created a VM on first host and it could successfully access the network. Now I migrated this VM to another host and the network access got denied. I would like to draw your attention here to the fact that *both my host though being in different subnets physically I have added them to the same cluster. Is it wrong or right?* The first host where the VM could access the network is in the same subnet as the guest ip addresses. But the second host where the VM cannot access the network is in different subnet than that of the guest ip ranges.
