Hi Guys,

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 :

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"}}')


Here is the output when I terminated the instance:
2012-05-02 06:44:04 TRACE nova.rpc.amqp Command: sudo /usr/local/bin/nova-rootwrap ovs-vsctl get Interface tap772ad8ff-89 ofport
2012-05-02 06:44:04 TRACE nova.rpc.amqp Exit code: 1
2012-05-02 06:44:04 TRACE nova.rpc.amqp Stdout: ''
2012-05-02 06:44:04 TRACE nova.rpc.amqp Stderr: 'ovs-vsctl: no row "tap772ad8ff-89" in table Interface\n'


Question/Problems:

1. Network with uuid 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=10.0.0.0/24 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?

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 ?

3. Would answer to 1 and 2 help in succesful launch of instances ? If not, what else do I need to do ?


Thanks,
Salman
