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>"<br>
This way you avoid creating a volume.<br>

You could edit nova.conf<br>

How?<br>
</blockquote>
<br>
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.<br>
I followed <a href="http://docs.openstack.org/mitaka/install-guide-obs/nova-controller-install.html" rel="noreferrer" target="_blank">http://docs.openstack.org/mitaka/install-guide-obs/nova-controller-install.html</a>, there aren't many options to configure and it defaults to local file storage.<span class=""><br>

You should try to fix that before you try to use it with openstack.<span class=""><br>

Didn't even knew you could do that. Thought you HAD to use cinder/swift..<br>

Please point me to a faq/howto/doc on how to do that, thanx!<br>

I used this guide:<br>
<a href="http://docs.openstack.org/mitaka/install-guide-obs/environment-networking-storage-cinder.html" rel="noreferrer" target="_blank">http://docs.openstack.org/mitaka/install-guide-obs/environment-networking-storage-cinder.html</a><br>
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.<br>
<br>

You could edit nova.conf to use local file system, just to have a running instance. If that works you can switch to another backend.<br>

I'll try that thanx. How do you do that with the "openstack" command?<br>

Try debugging your iscsi connection, maybe first without openstack.<br>

In my environment, I first tried to get all services running and working without external backends, cinder, glance and nova all ran on local storage.<br>

Then I tried other backends for cinder (iscsi), now all services use ceph.<br>

<br>
ceph?<br>
