TBH, I don't know what you mean with "Not image from server , real snapshot from the server" but, here's my attempt to answer your question.

It is possible to create snapshots of a specific instance using nova's image-create command. The operations executed by this command depend on the hypervisor you're using and the image type. As for libvirt and Qcow2, qemu-img snapshot will be used.

Once the snapshot is created, nova upload's the image to Glance and deletes it from the local disk.

Also, notice that, most likely, creating a snapshot will stop the guest instance and then restart it from its last state (saved before shutting it down). This also may very depending on the hypervisor you're using.

Hopes this helps!
