Virtual box intel vt-x error

Question

I tried to access the acceleration tap under system under settings and I can not. The tab is greyed out like their is no data available.

Only if your CPU (which?) supports VT-x/AMD-V you need to make sure you had [enabled it in BIOS](http://askubuntu.com/questions/256792/how-do-i-enable-hardware-virtualization-technology-vt-x-for-use-in-virtualbox/256853#256853). Some older CPUs (e.g. some Core2 Duo, Atom, etc.) may not support this. — Takkat, Apr 30 '14 at 06:45

If the corresponding Virtual Machine is running then the options under acceleration tab(Settings->System->Acceleration) would be grayed out.

So poweroff the virtual machine in-order to enable Hardware Virtualization(intel vt-x).

what do you mean – user276133 Apr 30 '14 at 05:27
it depends on the graphic card of your host machine. – Avinash Raj Apr 30 '14 at 05:29

If you have :-

Lest's try to reduce VirtualBox's base memory to be under 4 GB.
