Because the hardware features to permit efficient virtualization weren't 
available on i386-only CPUs. (And there's really no good reason to run a 
VM host [vs guest] in i386 mode if it can run in amd64 mode.)

It's certainly possible to run software-only virtualization on an 
ancient CPU, but at that point (since it would clearly just be to
scratch an itch, not for any practical reason) why ask for opinions 
instead of just playing around if playing around is the only goal?
