Problem is that Windows 8 (final version) does no longer support/recognize VT-x feature which is needed to fully support Virtualization. Virtualization is properly enabled in the BIOS settings (otherwise Windows 7 would not recognize correctly). Is this a problem with Windows 8 chipset drivers or what else is going wrong?  Also installation of Intel chipset driver version 9.3.0.1019 nor resetting the BIOS did not solve the problem. Any ideas???
