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;

# Nova-manage Service List

Nova-conductor node-0 Internal enabled:-) 2013-06-04 01:19:01

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 |
+-------------------------------------+----------------------------------------------------------+
| Status | ACTIVE |
| 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;
