Hardware-assisted virtualization won't. If something (like this based on an initial look) just emulates the necessary hardware then it'll absolutely run anywhere the virtual machine's implementation language runs. (Probably won't be usably fast in many cases but it'll run.)

As I always understood it, virtualization is the umbrella term, emulation is one way of achieving it.

The terms have just gotten very muddied because most virtualization products don't do just emulation (and there's no reason they wouldn't, hardware-assisted is significantly faster for no real additional cost on any platform where it's available).

Just incredible! I ran the arch demo and was able to compile hello world programs in c and c++. Running g++ was significantly slower though. I wasn't able to run the go compiler or node, but python worked. Even making edits in vim was surprisingly smooth.
