This is a commercial release. NEMS Linux for Single Board Computers is free to download and use. The Virtual Appliance however is a commercial build for business datacentres, and is only available on a subscription basis, or as a perk to those who support NEMS Linux on Patreon. An active subscription is required in order to operate the Nagios Enterprise Monitoring Server Virtual Appliance. Your ongoing support helps fund the development of NEMS Linux. If you are looking to obtain NEMS Linux for free, please check out one of the popular releases for Single Board Computers.

Before booting, you must configure your virtual Network Interface to use your actual LAN in Bridged mode.
While configuring your virtual Network Interface, you must generate a new MAC address for the virtual NIC. Record your virtual MAC address somewhere safe. Do not change your MAC address after initializing NEMS. Doing so would result in your HWID changing, which will disassociate your Virtual Appliance with NEMS Cloud Services.
x86 Virtualization must be available and enabled on your physical CPU in order to boot the Virtual Appliance. This is found in your host machine's BIOS/UEFI settings and will be called VT-x (Intel) or AMD-V (AMD), or something similar such as “Virtualization Extensions”.
