Well, I have a 64-bit

   Intel(R) Core(TM)2 Duo CPU T5250 @ 1.50GHz

and it does not have hardware virtualization support. This processor is
not *that* old. According to Wikipedia
even some 2011 processors (namely P6100 series) do not have
virtualization support. For the full list of which cpu's have/don't
have vmx flag see for example


So cpu's without vmx are not as ancient as they might appear.

HTH, :-)
