(#2) Handle add/remove/modify support for graphics devices

There's not dynamic update support for graphics devices.  If a user
add/removes/updates a graphics device while the guest is running, the changes
aren't picked up until the guest is restarted.

Updates from 1 to 2:
  -Fix typo in error message
