No.
is it safe to say that, by now, most modern systems come with VT or AMD-V support? and by "serious" virtualization, i don't mean someone downloading and goofing around with it, i mean people who want to set up virtual corporate servers or mission-critical stuff.
I run Windows as a guest OS on several machines. With the Intel vmx flag, performance is extremely good and quite usable.
Without the vmx flag, it is useless. It is too slow to tolerate.Most new machines now have the virtualization flags. It's always worth checking before you buy, though.
