AFAIK, KVM does not support host CPU's which don't have virtualization support. If OP has somewhat aged hardware, he may have no option but to use VirtualBox.
that would be some old crufty hardware, like pentium-4 (or the equivalent single core xeon stuff), hardly worth TRYING to virtualize on, except for very low performance 32-bit-only VM's, for test/dev kind of applications.
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

So cpu's without vmx are not as ancient as they might appear.
HTH, :-) Marko
