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
(http://en.wikipedia.org/wiki/Intel_VT-x#Intel_virtualization_.28VT-x.29),
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
http://ark.intel.com/Products/VirtualizationTechnology
So cpu's without vmx are not as ancient as they might appear.
HTH, :-)
