Well, you should ;-) How do you try to boot your instance, from CLI or  
Horizon? If it's Horizon, you would have to NOT klick the button  
"Create a new volume --> Yes" ;-) If it's CLI it's sufficient to only  
execute "nova boot --flavor <FLAVOR> --image <IMAGE-ID> --nic  
net-id=<NET-ID> (optional: only if you have multiple networks  
available) <NAME>"
This way you avoid creating a volume.

It's usually the default, although I'm really not an expert in  
Openstack. But if you simply try to set up nova on control and compute  
node following an install guide, it should bring you there.
I followed  
http://docs.openstack.org/mitaka/install-guide-obs/nova-controller-install.html, there aren't many options to configure and it defaults to local file  
storage.

You should try to fix that before you try to use it with openstack.

I used this guide:
http://docs.openstack.org/mitaka/install-guide-obs/environment-networking-storage-cinder.html
In the section for block storage it says "Block storage node  
(Optional)", so you wouldn't have to, but I guess it makes sense in  
the longterm. But as I already said, first you should try to get an  
instance running at all before using another backend.
