Ok, I followed this guide setting up my flat network. <a href="http://docs.openstack.org/trunk/openstack-network/admin/content/app_demo_flat.html">http://docs.openstack.org/trunk/openstack-network/admin/content/app_demo_flat.html</a> This first time I did
this, everything went great.
<div><br>
</div>
<div>I just changed my compute boxes /etc/network/interfaces to this:</div>
<div>
<div>jamski@FPCompute:~$ cat /etc/network/interfaces </div>
<div># This file describes the network interfaces available on your system</div>
<div># and how to activate them. For more information, see interfaces(5).</div>
<div><br>
</div>
<div># The loopback network interface</div>
<div>auto lo</div>
<div>iface lo inet loopback</div>
<div><br>
</div>
<div># bridge</div>
<div>auto eth0</div>
<div>iface eth0 inet manual</div>
<div>up ifconfig $IFACE up</div>
<div>up ip link $IFACE promisc on</div>
<div>down ifconfig $IFACE down</div>
<div><br>
</div>
<div>auto br-eth0</div>
<div>iface br-eth0 inet static</div>
<div> address 172.16.32.12</div>
<div> netmask 255.255.255.0</div>
<div> gateway 172.16.32.1</div>
<div><span class="Apple-tab-span" style="white-space:pre"></span># dns-* options are implemented by the resolvconf package, if installed</div>
<div><span class="Apple-tab-span" style="white-space:pre"></span>dns-nameservers 8.8.8.8 8.8.4.4</div>
<div># Management Network</div>
<div>auto eth2</div>
<div> iface eth2 inet static</div>
<div> address 192.168.0.3</div>
<div> netmask 255.255.255.0</div>
<div> </div>
<div>And now my compute box is on the data network also. However, no matter what IP address I give my VM, I cannot get on the network. I created a network 172.16.32.64/26 and assigned my VM to this network.</div>
<div><br>
</div>
<div>I remember last time I got this to work, I had to assign my VM the IP of my Network Box in order for it to get out on the internet. Now, no matter what IP I give the VM, I cannot get on the data network at all.</div>
<div><br>
</div>
<div>Here is my ip a from the compute box:</div>

<div>The first thing that jumps out at me is that your physical eth0 interface is attached to a bridge (br-eth0), and eth0 also has an IP address (172.16.32.12), and that IP address is on the subnet of your default gateway (172.16.32.1).</div>

<div>Because of how Linux is implemented, if you attach an interface to a bridge, then you can't put an IP address on the interface; you must remove the IP address from the interface and attach it to the bridge instead. For details, see the first question under
the heading "Configuration Problems" in the Open vSwitch FAQ <<a href="http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=blob_plain;f=FAQ;hb=HEAD">http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=blob_plain;f=FAQ;hb=HEAD</a>>. (Note: the same
issue exists for Linux bridges).</div>
<div><br>
</div>
<div>If your setup supports having a separate management network and data network (see <a href="http://docs.openstack.org/grizzly/openstack-network/admin/content/connectivity.html">http://docs.openstack.org/grizzly/openstack-network/admin/content/connectivity.html</a>),
I recommend using a router on your management network as your default gateway. In your case, it looks like you have a separate network on eth2, so if you change your default route to a router on your 192.168.0.0/24 network, it may clear up your problem.</div>
<div><br>
</div>
<div>In general, your compute node doesn't need to have an IP address on the data network. If you want it to have one, add it to one of the bridges rather than directly to eth0.</div>
<div><br>
</div>
<div>Hopefully, this will resolve your issue.</div>

<div>Ok, I'm pretty sure it has something to do with my compute box. everything else works. I can ping out from my network box but I can't ping anything from my compute box or VM. When I do a TCP dump on my Compute box and try to ping it from my network
box, I can see the requests coming in but the compute box never sends a response back to the ICMP. Im not sure whats going on.</div>

I have had to re-build my Compute box because I could was not able to get to the internet anymore through my VM once I had created the new network. So now I am back to trying to get my flat network up and running with my VM. For some reason, I cannot ping
anything from my compute box other than the management IP's. I followed the instructions on creating a flat network as before but this time its not working.
<div><br>
</div>
<div>the only thing I did different this time was in /etc/sysctl.conf I changed ipv4 ip _forward = 0 to 1. But this did not help. I am going to change it back.</div>

</div>
<div>Great! Now, you might have to assign the network to the project which you will be launching instances from. It'll be something like:</div>
<div><br>
</div>
<div>nova-manage network modify --fixed_range=<a href="http://1.1.1.0/24" target="_blank">1.1.1.0/24</a> --project=<uuid of project></div>
<div><br>
</div>
<div>check "nova-manage network modify" for more info.</div>
<div><br>
</div>
<div>Then if you do "nova-manage network list" you should see the project uuid listed for two different networks.</div>
<div><br>
</div>
