How to run virtual machine when my processor does not support virtualization?

I am using Windows XP 32-bit and have an Intel Pentium M 725 processor.

I used a software tool from Intel to check whether virtualization is allowed:

Supporting advaced Intel processor technologies
Intel(R) Virtualization technologies                       No

How do I enable virtualization for this processor?

Solution 1:

VMWare, for example, was around before hardware virtualization was common on desktop computers. So was QEmu as another example.

What happens here is that VMWare/QEmu would emulate the virtual CPU and hardware, instead of virtualizing it. This is much slower.

Neither VMware nor QEmu currently support running on a system without hardware virtualization (I could be wrong about VMware but I doubt it).

However, older versions of these programs (probably very old at this point) may work, if you can find them. I remember being unable to run VMWare Workstation on a 533Mhz AMD K6-2 Compaq due to lack of proper SSE support, but was able to on a built 1.3Ghz AMD Duron system. (I will tell you VMWare with 256MB of RAM is not pretty). I forget the specific versions involved but it did work. Barely.

You may have problems running Windows Vista or 7 under them, though.

To actually answer your question, if your processor doesn't support hardware virtualization, you can't enable it. If you have a crappy BIOS that disables it even though the system is capable of it, I have heard of BIOS mods that allow it to be enabled. However, your CPU physically does not have the feature so you are out of luck.
