Recently I am trying to setup Windows 2008 R2 as a Virtual Server using Sun Virtual Box on a Sony VAIO machine running Windows-7 64 bit version.
When ever I start the Virtual Server its keep on throwing an error as shown below:
"VT-x/AMD-V hardware acceleration has been enabled, but is not operational. You 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot.
Please ensure that you have enabled vt-x/AMD-V properly in the BIOS of your host computer."
Then I restarted my machine and went into BIOS setting. Within the BIOS setting goto Intel Virtualization Technology (2nd Tab in BIOS setting), by default it is disable. We have to enable for this setting for making Virtualization to work.
I am using Sony VAIO model number PCG-71312L.
