how to find out if my cpu supports 64-bit?

[Red Squirrel]

I have a quad core xeon I am leasing from The Planet and I've been wondering I could run a 64-bit VM on it. I have a feeling it's just a 32-bit cpu though, but is there a way I can find out for sure?

This is one of the cores if it helps:

Looks like it is a 32-bit processor.

Here's the output of my i7 920 in Linux for what it's worth.

There's no indication that it's 64-bits, but you can certainly look them up on either AMD or Intel's site.

Looks like it is a 32-bit processor.

Kind of figured, they are asking like 3x the price for 64-bit processors so figured it would be quite a fluke if I have one.

IIRC vmx is the flag for 64-bit on Intel CPUs.

Nope, it's "lm", i.e. long mode, you should look for.

Oh yea, I'm an idiot. VMX is the virtualization extensions for Intel.
