<font size=2 face="Courier New">Hello,</font>
<br>
<br><font size=2 face="Courier New">I am trying to deploy devstack in Dell
R910 with Ubuntu 12.04 as host OS. Currently one NIC eth1 is enabled in
the machine. The host machine is connect to open internet through eth1,
the eth1 gets IP from DHCP server. The eth1 ip is 10.135.0.11</font>
<br>
<br><font size=2 face="Courier New">My intention is to create CentOS VMs
with following property.</font>
<br><font size=2 face="Courier New">1. VMs should be able to ping each
other</font>
<br><font size=2 face="Courier New">2. VMs are accessible by ssh from any
host in 10.135.0.XX network</font>
<br><font size=2 face="Courier New">3. VMs should be connected to open
internet. </font>
<br>
<br>
<br><font size=2 face="Courier New">To do this I am following the All-In-One:
Dedicated Hardware method mentioned in </font><a href="http://devstack.org/guides/single-machine.html"><font size=2 face="Courier New">http://devstack.org/guides/single-machine.html</font></a>
<br>
<br><font size=2 face="Courier New">My localrc contains the following</font>
<br>
<br><font size=2 face="Courier New">disable_service n-net</font>
<br><font size=2 face="Courier New">enable_service q-svc</font>
<br><font size=2 face="Courier New">enable_service q-agt</font>

<br><font size=2 face="Courier New">enable_service q-l3</font>
<br><font size=2 face="Courier New">enable_service q-meta</font>
<br><font size=2 face="Courier New">enable_service quantum</font>
<br><font size=2 face="Courier New"># Optional, to enable tempest configuration
as part of devstack</font>
<br><font size=2 face="Courier New">enable_service tempest</font>
<br><font size=2 face="Courier New">DATABASE_PASSWORD=condor</font>
<br><font size=2 face="Courier New">RABBIT_PASSWORD=condor</font>

<br>
<br><font size=2 face="Courier New">FLOATING_RANGE=10.135.0.48/28</font>
<br><font size=2 face="Courier New">FLAT_INTERFACE=eth1</font>
<br><font size=2 face="Courier New">PUBLIC_NETWORK_GATEWAY=10.135.0.5</font>
<br>
<br><font size=2 face="Courier New">My observation is</font>
<br>
<br><font size=2 face="Courier New">public-subnet 10.135.0.48/28 is
created in admin project and private-subnet 10.0.0.0/24 is created
in demo project.</font>
<br>
<br><font size=2 face="Courier New">When I launch a VM instance in demo
project it gets IP 10.0.0.3, and on clicking associate floating ip, it
gets ip 10.135.0.50 successfully. </font>
<br>
<br><font size=2 face="Courier New">At this point at the shell of the above
VM ifconfig does not show up any ip. </font>
<br><font size=2 face="Courier New">I see one router1 is crated with two
interfaces, out of which External Gateway interface status with ip 10.135.0.49
is DOWN and Internal Interface status with ip 10.0.0.1 is ACTIVE. I am
not sure what the correct values should be, intuitively the External Gateway
should be ACTIVE. </font>

</font>
<br><font size=2 face="Courier New">mentioned that one need to enable bridge
FLAT_INTERFACE=br100. I am bit confused here. Should I use quantum or n-net?
If I use quantum should I use bridge or simple floating ip? Should I use
both floating ip and bridge? </font>
