[Openstack-operators] Starting large VMs takes quite long

I have set up openstack using stackops.
I have installed one controller node and one compute node (each using
two 1GBit NICs), following the book "Deploying Openstack".
I am using nova-objectstore for storing images.
Now starting a machine with a 5G image takes quite a while, probably
because the image is mounted via nfs to the compute node.
With libvirt, I am used to start VMs instantly. Is there a way to do the
same with openstack? The image would need to be stored directly on the
compute node, of course. Ideally, in a network with more nodes, the lots
of images I have would be distributed to compute nodes in advance, and a
special scheduler would select a compute node holding the needed image.
Is this possible with openstack?
