This exception usually happens when the virtualization of your CPU is disabled in the Bios. The modern computer has technologies that can be used to accelerate virtualization.
Reason to enable:
There is no major reason to enable it unless the user has the plan to use the virtual machines.
In order to fix this issue, you will have to try one of the following methods
Enable Intel virtualization in the Bios:
The first solution is to check whether you have enabled virtualization in your Bios or not. This solution is required at the system level and has to access your Bios. Windows 10 and 8.1 require VT-x/AMD-V enabled the process to accelerate the usage of desktop virtualization software like VirtualBox and Hyper-V.
The process to enable this feature is different in every computer and it totally depends upon your computer interface.
- I enable this by simply by the procedure;
- Open Bios
- Going to the bios tab
- Enable Intel Virtualization Technology
Enable the physical address extension:
Another reason for this error that your Physical Address Extension is disabled. This can be solved by;
- Get access to settings of your Virtual Machine through VirtualBox.
- Go to System.
- Click on the Processor tab
- Here check the Enable PAE/NX checkbox in the extended features.
