Error in VirtualBox – “This kernel requires the following feature not present on the CPU: pae”

    You may have come across the following error when running virtual machine(Kali Linux Operating System in my case) in VirtualBox.

This kernel requires the following feature not present on the CPU: pae

    Normally a 32-bit CPU can have access only up to 4GB memory(RAM). But with PAE (Physical Address Extension) enabled in VirtualBox, we can access more than 4GB RAM. This option should be enabled even if you are using 64-bit host machine with 64-bit or 32-bit virtual machine.

Steps to enable PAE:

  1. Shutdown the VM if powered on
  2. Right click VM -> Settings -> System
  3. Select Processor tab
  4. Check Enable PAE/NX checkbox and click OK.
  5. Start VM
  6. Enjoy !!!
