Problem 1:vmware Unable to identify the network card, causing the virtual machine not to surf

Issue 2:vmware The virtual machine cannot bridge the network adapter, prompting that it cannot be changed to bridge mode no bridged host network adapters

Problem Solving method

The default NIC type is incompatible due to a VMware virtual network card and Linux compatibility issues that cause the driver to not install properly

Locate our VMware Virtual Machine folder and append the VMware Virtual machine configuration (. vmx) to a setting of our NIC type ethernet0.virtualdev = "e1000"

Reason

VMware offers an old AMD pcnet10/100mbps virtual network card in a virtual client, and later, VMware provides 10/100/1000mbps performance with a similar partial virtualized vmxnet to optimize the virtual network card, with no doubt better performance. Now, VMware ESX server is already available with the Intel E1000-based Gigabit Virtual NIC, and E1000 is a better choice from a compatibility and performance standpoint. However, it seems that in the graphical interface of Esx/esxi 3.5, it is not possible to directly select the type of NIC, which requires manual configuration.

Type can select multiple items

A value of "e1000" specifies that the network card type is Intel (R) pro/1000
A value of "vlance" specifies that the network card type is AMD PCnet am79c970a (default is not compatible with this item)

A value of "vmxnet" specifies that the NIC type is VMware PCI Ethernet Adapter


After the modification, check our network card Inter can be used, AMD is still unable to enable the default

Problem Two Solutions

Set up VMware bridging settings, remove all bridging cards net0 Net8, then restart our PC, then click Restore Defaults to resolve

Cause: It should be due to the previous VM Nic not driving properly.
