<font style="font-size:10pt" color="#366092" face="Tahoma" size="2">Hi Guys,<br><br>I am having trouble with launching instances. The launch fails on networking task with status error. Here is the output (at nova-compute screen session) on launching instance :<br>
<br>2012-05-02 06:41:52 TRACE nova.rpc.amqp RemoteError: Remote error: QuantumNotFoundException (u'Quantum entity not found: %s', '{"QuantumError": {"message": "Unable to find a network with the specified identifier.", "type": "NetworkNotFound", "detail": "Network 5f227bba-eb3b-4dba-ad4c-b47c80aaffd7 could not be found"}}')</font> </div>
</div></blockquote><div><br></div><div>You're seeing this after a clean run of stack.sh (i.e., all databases wiped clean)? It seems like Nova knows about a network that Quantum does not. To me this looks like the same issue you reported before, where you deleted the network via Quantum API rather than using nova-manage, leaving the system in an inconsistent state. </div>
<div><br></div><div>I think we're going to need more information on this, such as your devstack config, any additional networks you've created, output of "nova-manage network list", how you're starting your VM (i.e., are you using --nic ?), etc. </div>
<div><br></div><div>I'd suggest you file an issue on <a href="https://answers.launchpad.net/quantum" target="_blank">https://answers.launchpad.net/quantum</a> so you can attach config, etc. But again, its important that you start from a clean run of stack.sh, especially if you've previously been tweaking things directly via quantum API. </div>

<br>Question/Problems:<br><br>1. Network with uuid </font><font style="font-size:10pt" color="#366092" face="Tahoma" size="2">5f227bba-eb3b-4dba-ad4c-b47c80aaffd7 is not a Quantum network (or may be its a quantum network but it doesn't belong to any tenant) . This network got created automatically when I ran stack.sh script and is associated with the fixed_range=<a href="http://10.0.0.0/24" target="_blank">10.0.0.0/24</a> in the nova.conf file. So problem here is that I wanted to launch this instance on a quantum network managed by a tenant/use (that I created before launching instance), how can I fix this?<br>
<br>2. Before running stack.sh, I could see gw-** port in my br-int bridge. Now it doesn't show up anywhere. Can you tell me what is the purpose of this port and how can I get it back in my br-int ?<br><br>3. Would answer to 1 and 2 help in succesful launch of instances ? If not, what else do I need to do ?<br>
<br><br>Thanks,<br>Salman<br></font> </div></div>
