Change network driver for ESX(i) guest OS to VMXNET

Hello,

On the VMWare ESXi server you can specifiy your network card driver when adding a network device to your virtual machine, but once installed you cannot change it through the GUI. So here are a few steps to make the change simple:

  1. Login to ESXi server through your terminal
  2. Go to your VM folder
  3. Connect to your VM and shut it down.
  4. Open your VM .vmx file with vi
  5. Look for the line ethernetX.virtualDev (X: interface number)
  6. Change this value to vmxnet or vmxnet3
  7. ​Save file and restart your virtual machine

Remark:
Usually you need to install the vm with another driver because vmxnet is not installed on an operating system per default. Before you can use the driver you must install VMWare Tools. It is important that you shut down the VM otherwise your modified .vmx file will be overwritten.
