Hi,
I have got to the point where I am trying to launch a virtual machine as
per
http://docs.openstack.org/folsom/openstack-compute/install/yum/content/running-an-instance.html
The boot command completes but it seems some key element of networking is
failing.
Does anyone have suggestions on how to trouble shoot this issue further?
$ nova boot --flavor 2 --image 9ed7b2c4-f296-4fd0-9ffa-026231947a09
--key_name mykey --security_group default cirros

But I notice that no IPV4 address has been assigned
If do nova lists during the boot process I see the following
$ nova list
+--------------------------------------+--------+--------+----------+
| ID | Name | Status | Networks |
+--------------------------------------+--------+--------+----------+
| fc0c5515-9d30-4263-87ea-0f912c0fc7c7 | cirros | BUILD | |
+--------------------------------------+--------+--------+----------+
$ nova list

+--------------------------------------+--------+--------+-----------------------+

+--------------------------------------+--------+--------+-----------------------+
$ nova list
+--------------------------------------+--------+--------+-----------------------+
| ID | Name | Status |

+--------------------------------------+--------+--------+-----------------------+

private=192.168.100.2 |
+--------------------------------------+--------+--------+-----------------------+
And if I wait some time and then repeat the nova list it will change to
$ nova list
+--------------------------------------+--------+--------+----------+
| ID | Name | Status | Networks |
+--------------------------------------+--------+--------+----------+
| fc0c5515-9d30-4263-87ea-0f912c0fc7c7 | cirros | ERROR | |
+--------------------------------------+--------+--------+----------+
The process does not seem to be getting as far as attempting to boot the
image
$ nova console-log fc0c5515-9d30-4263-87ea-0f912c0fc7c7
ERROR: The resource could not be found. (HTTP 404) (Request-ID:

There doesn't seem to be any obvious errors in /var/log/nova/network.log.

I am also seeing the following in /var/log messages. Could it be related
to the problem?
