Windows 7: Q9550 problems with Virtual XP

I have downloaded and installed Virtual XP and the setting up of the Virtual Machine seems to work until I get to just after I click Help Protect my PC and I get the error message:

'Virtual Windows XP' could not be started because hardware-assisted virtulization is disabled. Please enable hardware Virtulization in the BIOS settings and try again.

I have been in the Dell bios and enabled all 3 Virtulization settings and it still shows me the same message. Can anyone help?

Running Windows 7 64bit RC.

I am having the exact problem with the same setup. Dell optiplex 755 with 64 Windows 7 RC...All settings in Bios are enabled and I even made to sure update to the latest bios.

I can see a pattern here, I think the problem may be with you both having DELL

I have fixed it.

DON'T enable all the virtualization stuff, just enable the first one. Make sure the others (I/O and the bottom one) are disabled.

Fixed it for me.

Bingo, fixed my issue as well

thanks for the help...
