RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Pádraig Brady 2012-03-30 02:41:39 UTC 
Description of problem:
`nova flavor-list` returns 404.

Enabling debugging shows that the requested flavor URL is being routed incorrectly.

I rebuilt python-routes-1.12.3 for RHEL 6.2 and it worked fine.

A workaround for openstack-nova is to remove:
/usr/lib/python2.6/site-packages/nova/api/openstack/contrib/flavorextraspecs.py
though there may be other issue not encountered yet.
Comment 2 Pádraig Brady 2012-04-10 17:50:46 UTC 
The above issue impacted openstack diablo.

For reference another issue affecting the openstack essex release is,
this glance command:

glance -N http://192.168.122.106:5000/v2.0 -T glance-users -I admin -K secrete index

will throw:

File "/usr/lib/python2.6/site-packages/glance/api/middleware/cache_manage.py", line 80, in process_request
match = self._mapper.match(request.path, request.environ)

That's because the newer python-routes takes the environ parameter,
while the older does not.
Comment 3 RHEL Program Management 2012-09-07 05:08:41 UTC 
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unable to address this
request at this time.

Red Hat invites you to ask your support representative to
propose this request, if appropriate, in the next release of
Red Hat Enterprise Linux.
Comment 4 Alan Pevec 2013-11-28 16:59:38 UTC 
This was solved by introducing parallel installable python-routes1.12 package in EPEL6 and RHOS.
