What VPC is usually used by virtual machines, VMWare. After a virtual machine is installed, all virtual devices can be recognized by the virtual machine. However, what is striking today when we use VMware Server 2.0 x64 to create a virtual machine-the NIC driver is not found, for example:
But the system cannot identify the driver. To solve this problem, we need to install VMware Tools.
Solution:
Install a tool called VMware Tools.Click the install VMware Tools link on the Virtual Machine Mana
