Hi Sumit, It might be either a problem related with the routes version in RHEL or a problem with the API implementation, which has not been tested on RHEL. For instance, there might be a way for configuring the same routes without causing the error you have encountered.
I have filed a bug for this on Launchpad (https://bugs.launchpad.net/quantum/+bug/797419). Can you add some information concerning the environment on which you found the issue (mainly python and routes versions) to the bug report? Thanks, Salvatore -----Original Message----- From: openstack-bounces+salvatore.orlando=eu.citrix....@lists.launchpad.net [mailto:openstack-bounces+salvatore.orlando=eu.citrix....@lists.launchpad.net] On Behalf Of Sumit Naiksatam (snaiksat) Sent: 14 June 2011 17:18 To: openstack@lists.launchpad.net Subject: [Openstack] [NetStack]Quantum routes error Hi, I encountered a regular expression error when running Quantum service on a Red Hat installation. The Quantum service is not able to process any requests on account of which this error. The exception trace is appended to this email, but in short, the offending regular expression appears to be coming from the URL mapper for the "port" resource. After adding some debug statements to the code, it seems like that regex is: ^/tenants\/(?P<tenant_id>[^/]+?)\/networks\/(?P<network_id>[^/]+?)\/port s\/(?P<id>[^/]+?)\/attachment(?P<.format>[^/]+?)(/)?$ Trying to validate the above regex points to a "group" error. I am able to get around this by commenting out the mapper.connect() calls for the "port" resource in quantum/api/__init__.py I did not see this error when running Quantum on Ubuntu. Is this an artifact of an incorrect "routes" version that I might be running on RHEL, or is it something else? Any pointers are appreciated. Thanks, ~Sumit.
