So I had virtual box working perfectly before I decided to do a complete system wipe recently. Upon re-installing a 64 bit version of Ubuntu 13.04 and running a full upgrade, I attempted to set my virtualbox up again; however when ever I try to start my VM, I receive the following error:
Failed to open a session for the virtual machine Windows 7 x64 Ultimate.
VT-x is not available. (VERR_VMX_NO_VMX).
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: Console
Interface: IConsole {db7ab4ca-2a3f-4183-9243-c1208da92392}
I'm using the OSE version from the Ubuntu Software Center. I also tried the PUEL edition from oracle's website, no luck.
Any help?
