Re: [Openstack-operators] Help with simplest Quantum setup possible...


Make sure the quantum-dhcp and l3 agents are running and properly configured.  It sounds like either the q-dhcp agent is not functioning or connectivity between the dhcp agent and vm is not functioning.  If using GRE tunnels, test connectivity between the tunnel endpoints.  You should also see the IP's of your tunnel peers in ovs-vsctl show.  If your instance spawns successfully, console into it and manually assign an IP and ping the q-l3-agent and q-dhcp agent.  You can follow this guide for deploying Quantum with OpenvSwitch using GRE tunnels:

Subject: Re: [Openstack-operators] Help with simplest Quantum setup possible...


 Just for the record, I'll stick with Quatum + OpenvSwtich... Someone on IRC told me that it is the best way to go with Quantum.

 I'm still needing help to set it up (Single Flat / multi=false, still the same simplest topology).

 OpenvSwitch is already working, bridges `br-int' and `br-eth0' created...

 My main problem, I think, is that my Instances doesn't get an IP (they supposed to be at 10.33.14.X/24).

 Everything else seems to be working as expected, no apparent errors on the logs... quantum net-create / subnet-create worked...

 I appreciate any help, tips or docs!

 Sorry about the double posting... I need help!     :-P

 I'm trying, without any kind of success, to deploy OpenStack with Quantum on its simplest scenario, I think, which is `Single Flat' with `Linux Bridge' plugin.

 My topology is:

 1 firewall with 2 ethX (eth0 public, eth1 and
 1 controller with 1 eth0 (<> gateway
 1 node with 1 eth0 (<> gateway

 Instances Network:<> (Instances gateway must be, same router of the physical servers above, NOT its own host hypervisor).

 I'm trying this:

 http://docs.openstack.org/trunk/openstack-network/admin/content/demo_flat_installions.html - doesn't work... Even enabling OpenvSwith (but I don't want it for now, only Quantum instead of nova-network, with Linux Bridge for the sake of simplicity).

 The following guide help me a lot (with Nova Network everything is fine): http://openstack-folsom-install-guide.readthedocs.org/en/latest/ - I'm trying to follow it, by replacing nota-network instructions, for Quantum instructions but, doesn't work...

 Any docs or tips?

 NOTE: I do not want any kind of NAT (like nova-network multi=true) or `Floating IPs' within my Cloud Computing environment.
