    Hi Scott <br>
    <br>
    I have OVS. I did took a look to this document some time ago, the
    problem is that right now there is a mess in documention and you
    really don't know what's current and what's obsolete. <br>
    <br>
    I will take a look again and post if any doubts.<br>
    <br>
    Thank you for the reference. <br>

                Subject: [Openstack] OpenStack networking and disks...<br>
                <br>
                Hi,<br>
                <br>
                Is there any document that explains inner workings of
                neutron networking?<br>
                <br>
                I have an internal NAS that does not have support for
                openstack, and until we have resources to replace I want
                to use it to server iscsi disks.<br>
                <br>
                I can create disks by hand and associate to instances.
                But first I have to configure how will it connect to the
                network.<br>
                <br>
                <br>
                For now it's serving disks on a network that's
                accessible to the<br>
                floating ip network. That's not the best way but I
                cannot change it<br>
                because other instances that are not part of the
                openstack network are<br>
                using it. For example maas server.<br>
                <br>
                So I can add it another ip for each private network so
                it can serve<br>
                disks on the private/management net. But how do I
                configure virtual<br>
                routers so this NAS is accessible from private range
                (for ex.<br>
                <a href="http://192.168.10.0/24" target="_blank">192.168.10.0/24</a>).<br>
                <br>
                Is this the best way to do it?<br>
                <br>
                What's the best way to add servers that are not part of
                the openstack<br>
                deployment to the net, for example a nagios monitoring
                set for each<br>
                tenant so they have monitoring of their instances but
                they have not to<br>
                install.<br>
                <br>
                Best regards,<br>
