Hello, Oliver! Welcome to the Embedded Community! I checked with Casey, our product support engineer for embedded products and he said,
The CPU you have specified does indeed support Intel® Virtualization Technology (VT-x). The features included in the BIOS are enabled/disabled via the system manufacturer. If an expected
option does not exist in the BIOS, it could be that the feature is not supported. To investigate, you should contact the system manufacturer, Acer, to determine if a BIOS update is available that contains the options for which you are looking.
The ability to enable virtualization technology is often times named something else in the system
BIOS. It is also possible that the option exists in a BIOS menu that doesn’t ‘fit’ the user expectations. Again, check with the system manufacturer to see if they can point you to the option in the existing, or newer, system BIOS.
