Thanks.

Please note that you need AMD-V (or VT-x with Intel CPUs) in any case
if you want to use 64-bit guests. It does not matter if your CPU is
32-bit or 64-bit. Sorry, I fear your CPU will not support 64-bit guests.

If your CPU would support AMD-V there would be entries like Ubuntu (64-bit).
Because your CPU does not support AMD-V, you will not see these entries.

So no 64-bit support for guests, sorry.

Kind regards,
