Thank you for the feedback. I have a pretty good understanding of what each of the virtual switches are used for. But I still think that there has to be traffic through the service console NIC to get to the VM. The reason I am suggesting this is look what happens when a ESX server goes offline. The virtual machine must be migrated over to another ESX server in order to bring it up in the new ESX servers resources. If the VM was using only the VM virtual switch it should be able to continue to run on the orginal server right?
Please provide your thoughts.
