LAN set only between a virtual machine host mode

In order to better simulate the production server, you can perform the test in local virtual machine. Generally the actual production server is only the local host or within the same network, the virtual machine to set a fixed IP, select only the host mode for testing is particularly important.
Hostonly virtual machine network mode selection, i.e. only the master mode, setting fixed IP, and the same host.
