Sometimes we have several compute node. OpenStack is created by default, but we want to create a instance specific to a compute node, how do we do that?
1. View attached nodes
Check out which compute node we've hooked up, such as I've successfully hooked up node-1;node-0 is my controller node and my compute node;

2. See what image you have
# Nova Image-list
+--------------------------------------+--------------+--------+--------+
| ID | Name | Status | Server |
+--------------------------------------+--------------+--------+--------+
| fe64ff58-5a0d-48e0-972d-0f8455d28f1e |Fedora| ACTIVE | |
+--------------------------------------+--------------+--------+--------+
I have an image of Fedora 17. is downloaded on the Internet;
3. Specify compute node to create instance
$> Nova Help Boot
Use the above command. We have found such--availability-zone <availability-zone> the availability zone for instance placement. A parameter we can know compute node through it;
Like what:
$> Nova Boot--image Fedora--flavor 1 test1--availability-zone nova:node-1
We will create the Fedora image at the level of flavor 1, with the name Test1 created to the node-1 compute node;
4, verify where the actual start
# Nova Show Fd1
+-------------------------------------+----------------------------------------------------------+
| Property | Value |

| Updated | 2013-06-03t12:20:45z |
| Os-ext-sts:task_state | None |
|Os-ext-srv-attr:host | node-1|
I have successfully created it in node-1;
