Introduction
Deploying NComputings desktop virtualization in parallel with industry-standard VM technology
creates a synergy, delivering more power and flexibility than either technology can provide
alone. This guide is a compilation of tips and tricks to help you implement NComputing and
ESXi technologies in the most effective way possible. Before you begin, you should familiarize
yourself with the L300 deployment guide as it provides a groundwork understanding of a
standard installation of our product. This guide assumes a basic working knowledge of ESXi
and VMWare. You can find additional documentation from VMWare on their support site, linked
below.
If you do not already possess The L300 Deployment Guide, find it by
searching for L300 deployment guide on our Knowledge Base.

Adding USB Method 1 - Adding USB functionality while creating a Virtual Machine:
During the creation process of an ESX virtual machine, administrators can choose to
add a virtual USB hub to the VM. This step takes place near the end of the VM creation
process and is demonstrated in the images below:

If the NIC shows up in the Safely Remove Hardware wizard as seen above, you can
prevent accidental removal by doing the following:

2. Power off the virtual machine in question
3. Right-click the virtual machine
4. Click Edit Settings, then the Options tab
5. Click General, then Configuration Parameters, then Add Row
6. Insert a new row with the name devices.hotplug and the value false
7. Power the virtual machine back on.

When
deploying
multiple
cloned Virtual Machines from a
pre-built Master Image, DO NOT
REGISTER the Master Image.
Instead, register each individual
Image after it has been
deployed.
Follow the link below and search for keyword L300 for additional L300
configuration and feature information.
