this sounds like a good idea in general. Few interconnected questions

Who will handle the removal in case of problems? Engine after timeout?
Or is the only benefit that administrator can remove all disks in one
step by removing the VM?

Note that the uploads do not timeout at the moment. However strange that
might be. So I assume removing the disks/VM will be impossible anyway
because of locking.

The uploaded disks will still remain unattached though. Or do you plan
for Engine to create and attach the disks?

How will this be handled? Will Engine report the progress in the Virtual
Machines view and compute something based on the upload progress?
