This would serve goals like, for example: 1) running tests for applications with network processing capabilities without additional software packet generators; 2) making performance measurements with no hw inteference; 3) ability to run without root privileges, --no-pci, --no-huge, for CI build, so on. Maybe there's no such need, and these goals may be achieved by other means and this idea is flawed? Any thoughts?
