We've had a number of servers from Dell recently, all of which have had hardware-assisted virtualization disabled in the BIOS.
As far as I know hardware-assisted virtualization is a good thing - so why would Dell disable it? Does it have a performance overhead if the machine isn't acting as a virtual machine host? Are there any security issues?
In case it's relevant to your answers we will primarily be using:
- Host OS: Windows Server 2003 Enterprise R2 (32-bit)
- Guest OS:Windows Server 2003 Enterprise R2 (32-bit)
- VMM: Virtual Server 2005 Enterprise R2 SP1
