Abstract
A virtual computer system includes virtualization software, and one or more physical network interfaces for connecting to one or more computer networks. The visualization software supports one or more virtual machines (VMs), and exports one or more virtual network interfaces to the VM(s) to enable the VM(s) to access the computer network(s) through the physical network interface(s). The virtualization software modifies and filters network data frames from the VM(s) and from the physical network interfaces) to restrict one or more VMs to one or more virtual local area networks (VLANs) that are implemented within a VLAN topology. Restricting a VM to a VLAN Omits the broadcast domain to which the VM belongs, which may reduce security risks facing the VM. implementing the VLAN functionality within the virtualization software provides the functionality to every VM in the computer system, without requiring every VM to provide the functionality.
