I have been told that getting this to work with a laptop is rare. I own an MSI GT70-2PE.

Only a full reboot of linux fixes this issue. Qemu appears to corrupt something in linux when exiting. I get no error messages but windows 7 never finishes booting during the 2nd try. Apparently I do try to run vfiobind each time the script is run. Wondering if rerunning vfiobind can cause an issue?
