I currently have OpenStack installed (using the ManagedIT PPA) to use Keystone for authentication. However I'm still receiving a number of "Malformed request URL" messages, both in Dashboard as well as when using the Nova command line client. Also, some of
the Euca2ools command run OK, others (such as euca-describe-images) don't. I'm aware that not all the Euca commands are supported in Diablo, but currently I don't have any commands that let me launch instances.
<div><br>
</div>
<div>For example: euca-describe-availability-zones verbose yields</div>

</div>
<div><br>
</div>
<div>As mentioned, these error carry over to the Dashboard application. </div>
<div><br>
</div>
<div>Interestingly, I can create keypairs and create/modify security groups with no problems (using the Euca commands). None of the nova client commands execute without reporting a malformed URL request.</div>
<div><br>
</div>
<div>What am I missing today? I've checked keystone endpointTemplates (they're correct). The debug trace above shows that the request is authenticating w/ keystone correctly. Also, the request URI for the subsequent GET appear correct (to me, at least).</div>
<div><br>
</div>
<div>Finally, should the EC2/Euca commands work and support starting and stopping instances when using Keystone with Diablo? Life seemed so much easier before I decided to integrate keystone into my setup. Sigh…</div>
<div><br>
</div>
<div>Thanks in advance for any help or insight you might be able to provide. Additional details can be furnished as needed.</div>
