Could you please details the steps that helped fix your issue? I got the below error.
Failed to open a session for the virtual machine .
VT-x is not available (VERR_VMX_NO_VMX).

Please read the following FAQ, it deals with a closely related issue. FAQ: I have a 64bit host, but can't install 64bit guests.

I don't recommend that you try the OPs solution, which has no relevance that I can think of. I suspect that his actual "fix" was something else he did along the way, e.g. rebooting the host.
