The ovf update process decides which ovfs to update using GetVmsIdsForOvfUpdate query which checks if the db_generation column (vm) is bigger then the ovf_generation column (ovf_generation).
This column is not updated when importing devices and so the update process doesn't know that it should write a new ovf for the vm.
 
Usually the devices are imported to the engine before the first ovf generation and so are included in the generated ovf.

Missed 4.1.1, moving to 4.1.2. Perhaps it can make it to 4.1.1-1?

Ack from me, we want it in a async.

Verified on rhevm-4.1.1.6-0.1.el7.noarch
