+### Preparing a VmWare Fusion Host
+The *vmxnet3 driver* is required on a GigE Network Adapter used by VPP. On VmWare
+Fusion, the default Network Adapter driver is an *Intel 82545EM (e1000)*, and there
+is no GUI to change it to *vmxnet3*. The change must be done manually in the VM's
+configuration file as follows:
+
+- Bring up the VM library window: **Window -> Virtual Machine Library**
+- Right click on the VM where you want to change the driver:
+  <*VM-Name*> **-> Show in Finder**. This pops up a new Finder window with a line
+  for each VM that Fusion knows about.
+- Right click on the VM where you want to change the driver:
+  <*VM-Name*> **-> Show package contents**. This brings up a window with the 
+  contents of the package.
+- Open the file <*VM-Name*> **.vmx** with your favorite text editor.
+- For each Network Adapter that you want used by VPP, look for the 
+  Network Adapter's driver configuration. For example, for the VM's first
+  Network Adapter look for:
+  ```
+  ethernet0.virtualDev = "e1000"
+  ```
+  Replace `e1000` with `vmxnet3`:
+  ```
+  ethernet0.virtualDev = "vmxnet3"
+  ```
+and restart the VM.
+
+If you replaced the driver on your VM's primary Network Adapter, you will 
+have to change the primary network interface configuration in Linux. 
+
+First, get the new primary network interface name:
+```
+sudo lshw -class network -businfo
+
+Bus info          Device      Class          Description
+========================================================
+pci@0000:03:00.0  ens160      network        VMXNET3 Ethernet Controller
+```
+Replace the existing primary network interface name in `/etc/network/interfaces`
+with the above device name (ens160):
+```
+# This file describes the network interfaces available on your system,
+# and how to activate them. For more information, see interfaces(5).
+
+source /etc/network/interfaces.d/*
+
+# The loopback network interface
+auto lo
+iface lo inet loopback
+
+# The primary network interface
+auto ens160
+iface ens160 inet dhcp
