Dan,
I was trying the os-create-server extension that your mention in this thread but I am not sure if it will also limit the number of interfaces per VM. In my testbed, I have two (and maybe more) networks and every time I start a new VM, it comes up with two interfaces (one per network), does this extension should limit to one interface? If that is the case, then it is not working because my VMs always come up with two interfaces: stack@eperdomo-ubuntu02:~/creds$ nova list +--------------------------------------+------+--------+---------------- --------------+ | ID | Name | Status | Networks | +--------------------------------------+------+--------+---------------- --------------+ | d1df1b5a-7044-4fed-98b7-423362f1c47c | vm1 | ACTIVE | net6=10.0.6.5; net5=10.0.5.6 | | d693d99e-a7ef-45ef-a7c9-b3ecb5ff2645 | vm2 | ACTIVE | net6=10.0.6.6; net5=10.0.5.7 | +--------------------------------------+------+--------+---------------- --------------+ Basically, I just want one interface per VM, does it that possible?

You can use the os-create-server extension to do this. We recently added support for this extension to the nova client utility using the "--nic" option, though I believe it only went in during Essex-2, so I'm not sure if it would be in a distro like StackOps yet. The following command would create a VM connected to quantum network 0c02f3d3-204a-4e37-b820-5d15e6d74a9f. : nova boot --flavor 1 --image 07f3c46c-5062-4837-b43d-ec1a93b894dc --nic net-id=0c02f3d3-204a-4e37-b820-5d15e6d74a9f test1 Dan 2012/1/12 Dan Wendlandt <[email protected]> Hi Alisson, I assume you are following the directions as described at: http://docs.openstack.org/incubation/openstack-network/admin/content/ind ex.html? If so, then you have QuantumManager enabled in Nova and when you ran "nova-manage create network", this should have reached out to quantum to create a network, then stash that quantum network uuid in the nova db for future use. Can you try accessing quantum directly to see if that networks exist? Since you did not specify a "--project" when creating the network with nova-manage, QuantumManager will create the network with a quantum tenant-id set to the --quantum_default_tenant_id flag (defaults to "default"). So assuming the default, try running: bin/cli list_nets default What networks does this show? My best guess is that it will show only a single network: cbbbf92d-26d3-4a8d-8394-bb173fc35cbb, meaning one of your two nova networks show above was not created on Quantum. Is it possible that you created that network before enabling QuantumManager using the --network_manager flag? If so, you would need to delete that old network, and recreate it while Nova is using Quantum Manager. If both were created with QuantumManager enabled, then it is possible one of them failed. Can you find the network manager logs from the period when you ran the 'nova-manage create network' commands?

I installed a dual node OpenStack.diablo setup (controller and compute), which worked fine for instantiate a vm. Then, I installed OVS and Quantum. It seems that Quantum is working because I can create a network and attach an interface to it using $ python quantum/bin/cli: $ python bin/cli plug_iface $TENANT $NETWORK $PORT $VIF_UUID Plugged interface "foo" to port:5a1e121b-ccc8-471d-9445-24f15f9f854c on network:e754e7c0-a8eb-40e5-861a-b182d30c3441 I also can create a network using nova-manage: root@nova-controller:~/quantum-2011.3# /var/lib/nova/bin/nova-manage network create --label=public --fixed_range_v4=192.168.1.144/28 root@nova-controller:~/quantum-2011.3# /var/lib/nova/bin/nova-manage network list id IPv4 IPv6 start address DNS1 DNS2 VlanID project uuid 1 192.168.1.128/28 None 192.168.1.130 8.8.8.8 8.8.4.4 None None None 3 192.168.1.144/28 None 192.168.1.146 8.8.4.4 None None None cbbbf92d-26d3-4a8d-8394-bb173fc35cbb But when I try to boot a vm it remains in build status forever. The nova-network.log and nova-compute.log are below. It seems that the image cannot run because I did not assign a network to it, isn't it? How can I do this, I looked at the Quantum API (PUT, GET, POST...) but i can't use it, is it a user API or an API for communication between nova and quantum? I also did not see how to associate a vm to a network using nova-manage.
