VMware virtual machine network settings

1 VMware

VMware The network is set with bridge mode 、 Host mode 、NAT Pattern .
open edit -> Virtual Network Editor See the following .
VMnet0： Used for virtual switches in bridge mode
VMnet1： For virtual switches in host only mode
VMnet8： be used for NAT Virtual switch in mode
stay Windows Check the network connection on the host to see the virtual VMware Network Adapter VMnet1 and VMware Network Adapter VMnet8 Two virtual network cards .

2.1 Bridging mode

Bridge mode is to communicate between host network card and virtual network card by virtual bridge . It's similar to virtualizing a physical host as a switch , All virtual machines with bridging settings are connected to an interface of this switch , The physical host is also plugged into the switch , So all the network cards under the bridge are in switching mode , Mutual access without interference . 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 .
Such as 192.168.1 There are only 254 Host addresses , Therefore, the total number of virtual machines and physical in bridge mode cannot exceed this number .

2.2 NAT Pattern

Bridging mode may lead to some ip A shortage of resources , Now NAT Mode becomes the best choice .
stay NAT In the pattern , Host network card and virtual directly NAT Equipment connection , And then virtual NAT Devices and virtual DHCP The servers are connected together in a virtual switch VMnet8 On , In this way, virtual machine networking is realized .VMware Network Adapter VMnet8 Network card is to realize the communication between host and virtual machine .
NAT In this mode, the host is more like a virtual machine " Router ", adopt VMnet8 The virtual network card distributes addresses to virtual machines . Therefore, the virtual machine and the host are no longer under the same network segment , It can be understood as The host is a virtual machine " The superior ", This is why the bridge mode does not VMnet0 This virtual network card , because Virtual machines and hosts in bridge mode are " equality " Of , Share the same router .
NAT When the virtual machine in mode passes through the real host ip Visit the Internet .

2.3 Host only mode

Only host mode can be regarded as 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 ,Host-Only Mode separates the virtual machine from the Internet , Make virtual machine an independent system , Only communicate with the host .

3 To configure

3.1 Bridging mode

• Select the network connection mode as the bridge mode in the virtual machine settings of the system
• edit -> Virtual network editor settings .
  
  
  

3.2 NAT Pattern

NAT When the virtual machine in mode passes through the real host ip Visit the Internet .

3.3 Host only mode
