Open Stack

Hi,
I installed (with Packstack) the Havana release on 3 (virtual) machines each of them having 2 NIC configured with static IPs:

controller: 	keystone, glance, nova-api, nova-cert, 
		nova-vncproxy, nova-conductor, nova-scheduler
		neutron-server


compute:	nova-compute

network:	L3-agent, dhcp-agent,
		lbaas
		metadata

When I try to instantiate a VM, eventually it cannot reach the network:

$ nova list

The only log file where I see a strange (?) message is the server.log (of neutron-server) in the controller node; it says:

2014-01-05 22:16:12.005 1565 WARNING neutron.db.agentschedulers_db [-] Fail scheduling network {'status': u'ACTIVE', 'subnets': [u'677a1fb6-948d-4795-b20e-978b72987cc5'], 'name': u'ext-net', 'provider:physical_network': u'physnet1', 'admin_state_up': True, 'tenant_id': u'5a3847093ac24db4958eac2f3c39a604', 'provider:network_type': u'vlan', 'router:external': True, 'shared': True, 'id': u'defd117f-101b-4644-b3de-53745158d93b', 'provider:segmentation_id': 2L}

Here http://pastebin.com/kFpEs0D7, the Packstack’s answer file I used.

Could you please advice me where what I can investigate in order to understand why my VMs do not get the network after instantiated ?

many thanks,

	Alvise
