Answer 1

Turning PAE/NX on/off didn't work for me. I just needed to turn on virtualization on my computer. I was working on a HP Compaq 8200 and followed the steps below to turn on virtualization. If you are working on a different computer, you probably just need to look up how to turn on virtualization on your pc. The steps below for HP Compaq 8200 (or similar) is copied verbatim from the comment posted by the user qqdmax5 on Hp discussion board here.

To run Oracle VM Virtual Box / VMware machines on 64-bit host there is a need to enable Virtualization Technology (VTx) and Virtualization Technology Directed I/O (VTd).

Usually these setting are disabled on the level of BIOS.

To enable VTx and VTd you have to change corresponding settings in the BIOS.

Here is an example how to do it for HP Compaq 8200 or similar PC:

1. Start the machine.
2. Press F10 to enter BIOS.
3. Security-> System Security
4. Enable Virtualization Technology (VTx) and Virtualization Technology Directed I/O (VTd).
5. Save and restart the machine.

There is also some discussion on this on askubuntu.

Answer 2

I had this issue when tried to run a 32-bit OS with more than 3584 MB of RAM allocated for it. Setting the guest OS RAM to 3584 MB and less helped.

But i ended just enabling the flag in BIOS nevertheless.

step 1. Restart your PC and when your PC booting up then press your BIOS setup key (F1 or F2 or google it your BIOS setup key).

step 2. Go to the security menu.

step 3. Select virtualization and enable it.

Note:- BIOS setup depends on PC Manufacturer-brand.

Simply check how many CPUs you are allocating. With one CPU you do not need to play with your bios.

Make sure Virtualization is enabled in your bios.
