    Do you know CPU type? Is it Intel or AMD? Like Intel Xeon or Pentium? Go to servers BIOS and you will get information about CPU. For 64 bit cpu use 64 bit Linux operating systems. how much ram do you have in the system?

    PAE is only required when you use 32bit operating system and want to access 4gb or more RAM.

    I see, are you using virtual box or anything else to run virtual server?

    • Power off Virtual Machine
    • Click Machine -> Settings -> System -> Processor
    • Check Enable PAE/NX
    • Click OK
    • Start Virtual Machine
