Hi, I have lenovo thinkpad which is 64 bit processor and i have installed windows 7 professional, upon it, i have installed virtualbox and its addons. Now when i created a new virtualbox image and mounted ubuntu 64bit version image and started, it says "This kernel requires a x86-64 CPU, but only detected an i686 CPU. I have enabled virtualization technology in BIOS and checked. Same problem persists. Could anyone help me please ? I am attaching error - image for reference.

- 64-bit guests need hardware virtualization enabled in the host's BIOS (which means that you have to enable VT-x/AMD-V in your BIOS). Look at your user-manual for your specific model on how to do this.
- When creating the 64-bit guest VM you must select 64-bit variant of the OS (VM Settings -> General -> Basic -> Version).
- If another virtualization program is running and not "cooperating" you must disable it or uninstall it (see example below).
- If running Windows as host you must make sure Hyper-V or XP-mode is not enabled on the host.
