    I have added the iso for a Server 2008 r2 to my virtual box, and tried to boot for the first time but getting the error as below

    "VT-x/AMD-V hardware acceleration has been enabled, but is not operational. Your 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot."

    The CPU in my machine is 64bit so it should work fine, any ideas?

    for info, the motherboard I am using at home is: http://uk.asus.com/Motherboards/AMD_AM3Plus/M5A97/#specifications
    and the motherboard at work is just the basic that comes with the HP Compaq 6005 pro

    Have you got it enabled in BIOS?

    (not exactly same issue). Virtualbox forum is a good resource for clues

    Just tried it in VMWare Player and its working fine without any problems, all I can think is its a problem within Virtual Box for compatibility

    Any reason you weren't running Player to start with?

    I've always used Virtual Box as that's the one I started with and have kind of got stuck to, but I am fast moving away from that area now.
