what happen when snapshoting

Hi

I can't understand the process of getting snapshot in openstack, first time when creating a VM, Image stream from glance to compute node. compute node cache it and use as a base and common image for all same VMs, so we have a for ex. Ubunto01 Vm, consist of a point to base image in compute node disk, and some disk file (changes from base image). now, I get Snapshot from ubunto01, what will be happen? I will have a new image or machine with which files? I have one new .img or .qcow2 Image ? or a clone of Ubunto01 (consist of a point to base image plus some files)

Thanks all
