As part of change I362b3f8e91de79687fc84e256996fbcaf303b6af we put in a check to use udev to read GPT labels only if the version of udev installed supports that. Otherwise we fall back to sgdisk. The code currently falls back if udev version is <= 180. However, we're seeing version 219 on the latest release of Oracle VM (3.4.2) which still has this problem. Hence the check should be increased to 220.
