Caution - This section applies only to an Oracle Solaris 10 system. Do not configure the vsw interface on an Oracle Solaris 11 system.
By default, networking between the control domain and other domains in the system is disabled. To enable networking, the virtual switch device should be configured as a network device. The virtual switch can either replace the underlying physical device (nxge0 in this example) as the primary interface or be configured as an additional network interface in the domain.
Guest domains can automatically communicate with the control domain or service domain as long as the corresponding network back-end device is configured in the same virtual LAN or virtual network.
