“The first step is to enable it in your BIOS. In most computers it is disabled in the factory. Dell had disabled this feature on my Dimension 9200, I enabled it in the BIOS setup.”
How much is it possible?

[...] I had assumed that having the AMD/Intel virtualization mode was a big win, but it turns out that it really doesn’t help performance. Nonetheless, Virtualbox works fine. VT-x mode was originally turned forced off, and it was [...]

Have you done a comparison with a machine using the Nahalem processors? The statement is true with Core2 and older processors. However, Intel has done significant improvements with the Nahalem generation that it is no longer true. If you have core2 duo processor than stick with software virtualization. However if you have a Core i3/i5/i7, then by all means turn the Intel VT on.

Running Ubuntu 10.04 x64 as guest on Windows 7 x64 host, I can confirm that guest OS is much faster when enabling Intel VT. We use VirtualBox 3.2.8

The VirtualBox 2.2 User Manual states:

“… with version 2.2. … the hardware has significantly
improved with the latest Intel and AMD processors, and VirtualBox has also fine-tuned its hardware virtualization support to a degree that it is now faster than software virtualization in many situations.

Given that thius article is the first article that comes up on the Google search “vbox vt-x,” perhaps the author would consider modifying it to state that the text is true only for older versions of VirtualBox.

Since version 2.2.0, the VT-x/AMD-V feature is enabled by default on newly created VMs. This may indicate some progress, but I haven’t made any benchmark.
