Yes that is the problem, in your case you may want to try to pass the
hypervisor to the network drivers so they can get the networking
interfaces of the VM.

OK

Perfect

The Datastore do not make any modification to the image, if you want
to use qemu, you should do a "qemu-img convert" on it before
registering it. The fs Datastore can handle both formats, there is a
special transfer mechanism (TM) for qcow images that takes advantage
of the cow features.
