    Hi ravindra ,

    Please make sure that the virtualization in BIOS is enabled upon booting.

    Hi Yusuf,

    Can you please check to make sure that hardware virtualization is enabled in BIOS on your host machine? You can find more information on 64 bit guests instances in VirtualBox here (see section “Does VB support 64 bit guests?”):


    Hope this helps.
