I'm try to use the virtualbox to virtualize a 64-bit system but the error that I get is:
La aceleración VT-x/AMD-V ha sido habilitada, pero no es funcional. Su sistema invitado de 64-bit fallára al detectar una CPU de 64-bit y no podrá arrancar.
Compruebe que VT-x/AMD-V están habilitadas en la BIOS de su computadora anfitrión.
For the ones not knowing Spanish, google translate gives:
VT-x/AMD-V acceleration has been enabled but is not functional.
Its system of 64-bit guest will fail to detect a 64-bit CPU and will not boot.
Check VT-x/AMD-V are enabled in the BIOS of your host computer.
I've checked the AMD V CPU Virtualization Extensions with the following command:
grep --color svm /proc/cpuinfo
The output is:

Run the command:
grep -o "^flags\s*:.*\ssvm\(\s\|$\)" /proc/cpuinfo
the output is:

so, It's possible fixed it's from the bios or otherwise.
How to fix the mistake? Is it possible at all?
