A virtual network device is a virtual device that is defined in a domain connected to a virtual switch. A virtual network device is managed by the virtual network driver, and it is connected to a virtual network through the hypervisor using logical domain channels (LDCs).
A virtual network device can be used as a network interface with the name vnetn, which can be used like any regular network interface and configured with the Oracle Solaris 10 ifconfig command or the Oracle Solaris 11 ipadm command.
You can add a virtual network device to a domain, set options for an existing virtual network device, and remove a virtual network device by using the ldm add-vnet, ldm set-vnet, and ldm rm-vnet commands, respectively. See the ldm(1M) man page.
