I have configured Openstack Havana in a single machine using Neutron for networking. When I try to deploy a VM it always shows this error:

{u'message': u'Timeout while waiting on RPC response - topic: "network", RPC method: "get_instance_nw_info" info: "<unknown>"', u'code': 500, u'details': u'  File "/usr/lib/python2.7/dist-packages/nova/compute/", line 258, in decorated_function |||     return function(self, context, *args, **kwargs)

Any ideas on what's wrong?

Please check for errors in neutron service logs. Post them here if required.

I'm having the same issue. I read some information about auth_uri parameter (in neutron.conf) so I setted it but I still have this exception. My instances are in error and when I try to delete them, I'm having a similar exception (RPC method "get_instance_nw_info"). How do you resolv your problem ?

Edit : I finaly found the reason of my problem : the nova configuration about neutron network usage on my hypervisor was incorrect (nova.conf). I just had to copy the configuration of neutron from the nova.conf of my management node.

I'm having the same issue. What exactly did you copy over?

Adding the following directives to nova.conf on the compute node and restarting the nova-compute service resolves this issue for me.

network_api_class =
neutron_url = http://controller:9696
neutron_auth_strategy = keystone
neutron_admin_tenant_name = service
neutron_admin_username = neutron
neutron_admin_password = password
neutron_admin_auth_url = http://controller:35357/v2.0
linuxnet_interface_driver =
firewall_driver = nova.virt.libvirt.firewall.IptablesFirewallDriver

I also submitted bug #1251096 against the installation guide.

thanks, it helped. it seems that in Havana the auth_uri variable must be set, although there is no mention of it in the openstack docs

I'm having the same issue. Where did you set it?
