Is there any incentive to create VLANs for virtual machines?
A VLAN (Virtual LAN) is a set of computers that are configured to communicate with one another as though they resided in a common broadcast domain, regardless of physical location. In a virtualized environment, the physical location of a virtual machine is ambiguous, to say the least. Since physically connecting a virtual machine to the desired network segment may not always be an option, VLANs offer an ideal solution for creating the desired network topology in a virtualized environment.
