FW: Associating VM to a quantum network

 

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?

 

Thanks,

 

Edgar

Yes Dan, you are right.
I am using the stackOps distro, and the network 1 was created before
quantum instalation, i don't know how neather why. 

	
	Now I have these two networks

	Anyone knows how can i instantiate a vm and associate it to one
of these networks?

 

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

	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? 

	 

	Thanks,

	 

	Dan

		Hello everyone,
		
		I need some help to instantiate an image and associate
it to a quantum network.
		
		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

		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

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.
