To understand the utility of this specific file, it helps to break down the standardized naming convention Cisco utilizes for its virtual appliance images:
Newer "XRv 9000" images require 16GB+ of RAM. The classic XRv (6.1.3) runs smoothly on 3GB, allowing you to run 10+ routers on a standard laptop.
