    VirtualBox: Is PAE/NX option dangerous for the system?

    Hi everybody,

    I'd like to install Kali Linux on a Virtual Machine in VirtualBox.
    At startup it failed because it did not have the PAE, so I've enabled it and checked. Everything works fine, but an horrible doubt came up into my mind: as PAE exposes the Physical Address Extension, could it be dangerous to my Host system (which is Windows 10) or, worse, my computer?

    Thanks a lot for your help!

    EDIT: and the I/O APIC? I do not actually know what it is, but a tutorial advised me to turn it on. Could it be dangerous for my system (not Kali Linux, I sincerely don't care if my Kali Linux machine is destroyed, the most important thing is that my Windows - Host - and my computer are damaged in no ways)?

    Neither PAE nor I/O APIC have any implications for the host computer or OS, only the client. Read the VirtualBox help files for more information on these settings. They explain it better than I can.
