Comment 12 for bug 1561019

I think I understand... x86_cpu_change_kvm_default("svm", NULL) causes the default of "off" to be removed for compat levels of 2.1 and older... So what we actually want is either move that line to be applied for all compat levels or remove them and also remove the default of "off". Like below (but I want to test this first):
