[one-users] an error associated with onevm delete of persistent image

[Ruben S. Montero]

Hi Hyunwoo

Yes totally right, this is in fact a bug that has been solved in recent
versions of OpenNebula... In this situation, the delete operation will
leave the persistent images in the error state so the consistency of the
image can be checked. OpenNebula will not try to move the image back to the
datastore. oneimage enable will activate the image again.


Cheers

Ruben
