Everything seems to be executing correctly now, even after repeated
insmod/rmmod

seems like i was loading the module, the process associated with it was
"almost always" scheduled to be ran on the same logical processor,
therefore when i was executing `vmxon` on a processor alreading running
vmx, it was failing (again, not sure...). gonna have grey hair soon

semi-feat: sometimes vmxon executes successfully, most of the time the CF (Carry Flag) is set to 1..
