Connect virtual machines to a vSphere distributed switch either by configuring an individual virtual machine NIC or migrating groups of virtual machines from the vSphere distributed switch itself.
Connect virtual machines to vSphere distributed switches by connecting their associated virtual network adapters to distributed port groups. You can do this either for an individual virtual machine by modifying the virtual machine’s network adapter configuration, or for a group of virtual machines by migrating virtual machines from an existing virtual network to a vSphere distributed switch.
