OpenStack: add security rules failed due to multiple security groups named with "default"
<p>After installed devstack, I follow the <a href="http://docs.openstack.org/developer/devstack/networking.html#defaults" rel="nofollow">doc</a> to set security rules:</p>

<pre><code>$ openstack security group rule create --proto icmp --dst-port 0 default
More than one security_group exists with the name 'default'.
</code></pre>

<p>It claims I have multiple security_group which named with <code>default</code>, but I check with <code>nova secgroup-list</code>:</p>

<pre><code>$ nova secgroup-list
WARNING: Command secgroup-list is deprecated and will be removed after Nova 15.0.0 is released. Use python-neutronclient or python-openstackclient instead.

| e5466481-f656-46fa-ac72-56f7ab118c70 | default | Default security group |
+--------------------------------------+---------+------------------------+
</code></pre>

<p>So, there is only one security group named with <code>default</code>... </p>

<p>Could any one give me some suggestion about that?</p>
