I was scrolling in my XP log and couldn't find a reference to VT-x. Also, do you have an ideia on how can I do some simple benchmarks, to assess VT-x performance? Is there any information in log I can use for that purpose? Instead, we make partial use of it -- only where it makes sense and where it helps us to improve performance. VT-x support is not of high practical importance and we have noticed that our implementation of AMD-V is currently even slower than VT-x.
Over time we plan to improve it but it's not our top priority right now. To satisfy my curiosity, I used Passmark to benchmark, results show Guest improves a bit but there's a graphical penalty. In my case, I'm probably only enabling it when mandatory. I couldn't do 3D bechmarks in either case, in Vista, Passmark required me to download DirectX9 I'm not that curious to downgrade it. But the good news - I guess - is that with VBox 2. Board index All times are UTC.

Link copied. Do you like this post? Intel and AMD processors have support for so-called hardware virtualization. This means that these processors can help Oracle VM VirtualBox to intercept potentially dangerous operations that a guest operating system may be attempting and also makes it easier to present virtual hardware to a virtual machine. These hardware features differ between Intel and AMD processors. The Intel and AMD support for virtualization is very different in detail, but not very different in principle.
As opposed to other virtualization software, for many usage scenarios, Oracle VM VirtualBox does not require hardware virtualization features to be present. Through sophisticated techniques, Oracle VM VirtualBox virtualizes many guest operating systems entirely in software. This means that you can run virtual machines even on older processors which do not support hardware virtualization. Even though Oracle VM VirtualBox does not always require hardware virtualization, enabling it is required in the following scenarios:.
For virtual machines that are configured to contain such an operating system, hardware virtualization is enabled automatically. This is not much of a limitation since the vast majority of bit and multicore CPUs ship with hardware virtualization.
