Open Stack

Can you verify your glance endpointTemplate is http://%HOST_IP%:9292/v1 ? 
Hard to tell from the trace below if the "v1.1/1/images/detail" is against 
the Nova API or Glance API.

Subject:        [Openstack] Nova command line versus Euca2ools
Sent by:        openstack-bounces+mjfork=us.ibm.com at lists.launchpad.net



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. 

For example:  euca-describe-availability-zones verbose yields

root at nova:~# euca-describe-availability-zones verbose
AVAILABILITYZONE nova available
AVAILABILITYZONE |- nova 
AVAILABILITYZONE | |- nova-network enabled :-) 2012-02-06 22:15:16
AVAILABILITYZONE | |- nova-scheduler enabled :-) 2012-02-06 22:15:15
AVAILABILITYZONE | |- nova-vncproxy enabled :-) 2012-02-06 22:15:14
AVAILABILITYZONE | |- nova-compute enabled :-) 2012-02-06 22:15:07
AVAILABILITYZONE |- nova1 
AVAILABILITYZONE | |- nova-compute enabled :-) 2012-02-06 22:15:08

however, euca-describe-images yields (with debug enabled)

The corresponding nova command yields the following (again with debug 
enabled)

novaclient.exceptions.BadRequest: Malformed request url (HTTP 400)

As mentioned, these error carry over to the Dashboard application. 

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.

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).

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…

Thanks in advance for any help or insight you might be able to provide. 
Additional details can be furnished as needed.

Regards,
Ross
