I'm trying to implement this architecture:<br>
<ul>
<li>RDO on CentOS 6.5 installed via packstack<br>
</li>
<li>nova networking. Not neutron.</li>
<li>flat network<br>
</li>
<li>one control host (single NIC)<br>
</li>
<li>initially, one compute host with another to be added ( 2 NICs)<br>
</li>
<li>My internal office network is 192.168.0.0/16, and
192.168.20.0/24 is dedicated to the floating IPs for our
OpenStack cloud</li>
</ul><p>Much of the network documentation leaves out on which host the
specific configs are to be done, so it's not clear to me how to
prepare my hosts for openstack installation. There are
indications that some nics should have no IP address assigned but
rather be part of a bridge which has the IP address, but the docs
are vague about that and different architectures seem to need
different configs.<br>
</p><p>Packstack may be complicating things -- at least in my mind --
since I'm not sure what network configuration puppet is
implementing via packstack and what I have to do before the
install.<br>
</p><p>My primary question is, "How do I set up my network before
installation?"<br>
</p><p>My Ethernet interfaces are em1 and em2. Here's my understanding
at this point: <br>
</p>
<ul>
<li>I will use em1 as the management interface, which I should
configure with an IP address (already has this address...just
leave this interface as is) <br>
</li>
<li>The em2 interface is the one that will interface with my VMs
via a bridge (br100), so that interface should not have an IP
address, because the bridge will.</li>
</ul><p>What parts of this have to be set up before the installation?<br>
</p><p>Thanks!<br>
