Are you cloning/uploading an existing image to open nebula?. 

I'm
using ceph datastore too. My kvm template image is a 21GB qcow2 (and
raw) image but only 1.5GB of space is taken up. (that is before
uploading to nebula). 

Images that will be stored in ceph will be
converted to RBD and when nebula "sees" that a this disk is 21GB, it
will be allocated. The allocation time will depend on how fast your ceph
network is. 

And have you tried creating an empty datablock? Create an
empty datablock in the ceph datastore and then install linux on that
datablock, the allocation of an empty datablock is faster, though you'll
need to install the OS afterwards.

When I create VMs from image which located on ceph datastore, OpenNebula
do full clone of that image - it takes precious time. Is it possible to
tell do something like just quick snapshot and than working with it with
VM?
