The images will use the drivers of the Image Datastore. In your case, take
a look at the Filesystem Datastore guide [1], it has a section on the
shared TM drivers, and another on the qcow2 drivers.

Basically, a VM using persistent images will be deployed immediately while
a VM with non-persistent images will need to wait for the files to be
copied to the system DS.
