Hi,
I'm a new user of Oracle Virtualbox. I have followed instructions and created a new VM and set it up so the DVD drive points to an Windows XP "ISO" file.
When I set it running I get the following error :

"Failed to open a session for the virtual machine XP.
Not in a hypervisor partition (HVP=0) (VERR_NEM_NOT_AVAILABLE).
VT-x is disabled in the BIOS for all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED).
Result Code: E_FAIL (0x80004005)Component: ConsoleWrapInterface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}"

I don't understand what the issue is and therefore what to do about it.
Any advice really appreciated.
Thanks in advance, Graham.

Either your computer's "virtualization technology" (VT-x / AMD-V / SVM) is not on in the BIOS or Hyper-V is active. Go through everything in:

I have a 64bit host, but can't install 64bit guests

Thank you Scott.
My i5 processor supports VT-x but it wasn't enabled in the BIOS.
So looks more promising.
Thanks again, Graham.
