Thanks for a very nice explaination.

I am a VB 6/.Net programmer and need different versions of software to support my various clients.

I am about to upgrade my laptop (Pentium 1.6, 3GB, 320GB) and use XP inside host Vista's Microsoft Virtual PC extensively to run some old versions like SQL Server 2000 while my host Vista runs SQL Server 2008.

I was wondering if an Intel processor with hardware virtualization would make more sense than one without it. If there is not much speed difference/improvement between the two, I would like to save some money and choose a Dell Studio with Intel's T6600. Please advise.

Thnaks and regards
Kapil

Hi Gleb.

I am concerned about one thing.
Does virtualization affect system performance if I actually have no software that uses this feature? Will i benefit from disabling this feature? Or it doesn't matter?

Thanks,
Andrei

Is Vmware hardware or software virtualization?

Might be beneficial to update the article with new info — VirtualBox is now at version 3.0, can use hardware virtualization, and has a host of new features such as DirectX and OpenGL support in guest operating systems.

Gleb, Thank you for clearing the air about it. The title "hardware virtualization" really leaves a false impression of what you pointed out in Misunderstanding #2. It has seemed to make sense logically that with multiple cores, one could have dedicate a core to each OS if you wanted to thinking you could have true parallel multi-tasking (I.e. running two independent tasks on two seperate cores during the same cpu cycle) rather then the way multi-tasking is defined today with preemptive and cooperative.

I hadn't even heard of this until I recently updated my hardware at home with an intel quad core and was wondering what this hardware virtualization thing was.

Thank you for your time to help clear this up
