  You may be able to get away with just the "set" call. Given that all h/w that is supported by bhyve, with the exception of only Nehalem systems, support this, you may want to use just the error from the set call to handle this low-probability error.
  
  Note that AMD SVM has always supported this mode. "Unrestricted Guest" is an Intel-only feature, but given that the name is baked into a bhyve API already, there doesn't seem to be any harm in keeping it going.
