Comment 3 John Schwarz 2014-08-20 04:55:18 EDT

Please provide the version of python-neutronclient you used in this test.

Comment 4 Toni Freger 2014-08-24 04:05:05 EDT

python-neutronclient-2.3.4-1.el6ost.noarch

Comment 5 John Schwarz 2014-08-25 07:45:31 EDT

This bug is caused by an inappropriate version of python-httplib2 version (>=0.7.5 is needed but not enforced by neutronclient's RPM spec).

I reproduced this error for python-httplib2 0.7.2 and traced it back to a duplication of port-create request. After upgrading python-httplib2 to version 0.7.7, the problem did not reproduce for 160 VMs.

*** This bug has been marked as a duplicate of bug 1133511 ***

Comment 6 John Schwarz 2014-08-31 06:32:35 EDT

Please check this again, but this time make sure (manually) that python-httplib2's version is >=0.7.5.

Comment 7 Roey Dekel 2014-09-02 04:07:31 EDT

pls add "Fixed In Version", to check if fix merged to puddle.

Comment 8 John Schwarz 2014-09-02 04:10:08 EDT

Done
