Deployment Notes
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”.
