Hi to everyone:
I have virtualbox_bin 3.0.2-2 with multiple operating systems and from a recent update (maybe 12 or July 15) I have stopped running 64-bit versions that I installed.
When I'm launching a 64-bit machine, appears it the following:VT-x/AMD-V acceleration has been enabled, but is not functional. Its 64-bit guest fails to detect a 64-bit CPU and can not start (boot).
Please make sure that you choose. VT-x/AMD-V properly enabled in the BIOS of your host computer.
Then a couple of buttons: Close Virtual Machine
. When you press the Continue
button, the operating system normally loads the GRUB and then:This kernel requires an x86-64 CPU, but only detected an i686 CPU.
Unable to boot - please use a kernel Appropriate for your CPU.
Anyone know how to fix it
