I am working on deploying some new VMs to demo some of the latest Nexenta products but I found one issue instantly.  The deployment requires 10 Gbps networking and since it is all internal to my macbook I assumed this would be easy.  Unfortunately VMware Fusion 7 does not have a graphical way that I can find to change the type NIC.  Turns out this is very easy and I thought I would share the process so here goes..

1. Build the VM with whatever number of NICs you need.
2. Power off the VM
3. Quit VMware Fusion
4. Go to the location of the virtual machines
5. Right-click on the VM you want to edit
6. Select “Show Package Contents”
7. Right-click on the .vmx file and open with TextEdit
   • Make sure you open Preferences and uncheck “Smart Quotes” if you dont it adds stuff into the VMX file
8. By default all the NIC will show as e1000, you need to change them to vmxnet3.  Find this line: ethernet0.virtualDev = “e1000” and change the e1000 to vmxnet3
9. Save the file
10. Open Fusion and Start the VM

Thats it!
