@wido , thanks for your reply. As I know, there are still many people using
Ubuntu 12.04. Especially for one starting using CloudStack/Ubuntu 2-3 years ago
( before Ubuntu 14.04 release), it is difficult for them to (live) upgrade
their production to CloudStack 4.9/Ubuntu 14.04 or 16.04. I think it is better
to be compatible with Ubuntu 12.04, by disabling the feature.
