It looks like the attempt to execute 'path/to/qemu-system-x86_64 
-version' is failing, leaving an empty string instead of version output. 
  Could this be a SELinux issue preventing the execution of a file as 
root that doesn't have proper labelling?  Does an strace yield any hints?

Particularly since the same file can be executed as non-root?
