One 、 Bridging mode

Network connection via bridge mode , The virtual network adapter in the virtual machine can connect to the physical network adapter in the host system , In bridge mode , virtual machine ip The address needs to be in the same network segment as the host , If networking is needed , Then the gateway and DNS It needs to be consistent with the host network card . But the problem with bridging is when you change the location of your office （ The external network has changed ）, The virtual machine IP The earth

The address and gateway should also be changed manually , so much trouble .

Two 、nat Pattern

Use NAT Mode network , Virtual machines don't have to have their own... In an external network IP Address . A separate private network will be established on the host system . In the default configuration , Virtual opportunities pass through this private network DHCP The server gets the address . Virtual machine and host system share a network identity , This identity is not visible in the external network . stay NAT In the pattern , Host network card and virtual directly NAT equipment Connected to a , And then virtual NAT Devices and virtual DHCP The servers are connected together in a virtual switch VMnet8 On .

3、 ... and 、 Host only mode

Host-Only The pattern is actually NAT Patterns remove the virtual NAT equipment , And then use VMware Network Adapter

VMnet1 Virtual network card connection VMnet1 Virtual switch to communicate with virtual machine Believable ,Host-Only Mode separates the virtual machine from the Internet , Make the virtual machine an independent system system , Only communicate with the host .
