If you have a virtual app with stopped virtual machines and then you try to bundle the images of the bundle, the process powers on the stopped virtual machines and then power off them again to bundle them.

This power-on / power-off can break the virtual-disk because of an non-orderly shutdown of the system and should be avoided.

There is also another error in the process, the 'process' popup disappears but the system is still copying the images and removing them without information of the progress. The process completes succesfully, but meanwhile a user can start/stop the virtualapp o the virtual machines being copied or removed.
