Arindam,



You need to make sure that nova-network
is not started and that quantum is started on your control node.  Also
ensure that your /etc/nova/nova.conf is configured to use quantum and a
plugin.



For my setup I have:



network_api_class = nova.network.quantumv2.api.API

quantum_admin_username = <username>

quantum_admin_password = <password>

quantum_admin_auth_url = http://localhost:5000/v2.0/

quantum_auth_strategy = keystone

quantum_admin_tenant_name = service

quantum_url = http://localhost:9696/

libvirt_vif_driver = nova.virt.libvirt.vif.LibvirtOpenVswitchVirtualPortDriver

linuxnet_interface_driver = nova.network.linux_net.LinuxOVSInterfaceDriver

linuxnet_ovs_integration_bridge = br-int

quantum_ovs_bridge = br-int



In the default section of my nova.conf.
 Obviously those will vary depending on your hypervisor and which
plugin you are using.

Hi,

Actually the problem was solved by installing nbd module. Now I have one
weird problem. I have mistakenly installed nova-network in compute node
and it had became the default one. Can you tell be how to fix it?

Arindam, 



I realized last night that the iptables command I sent didn't have the
right network interface specification for your environment.  




It should have been:  iptables -I INPUT -i <interface on control
node to the compute nodes> -p udp --dport 67:68 --sport 67:68 -j ACCEPT
. 



It looks like that might be vnet0?  Sorry, I don't use iptables much
and just stumbled upon the fix for our environment out of luck.  :-)

Hi, 



A place to look for eventually error messages is also /var/log/messages.
Look for dnsmasq related message and post them here.

I am really stuck, any help will be highly appreciated.



I installed a two node openstack deployment on debian wheezy:

But when boot up a vm(the cirros from the tutorial), it dont get any ip.

In controller or compute node the nova-network.log does not generate any
logging of events.



on the horizon I dont have any network listing.
