<span style="font-size:10.0pt;font-family:"Helvetica","sans-serif"">Hi All,<o:p></o:p></span></p>
<p style="mso-margin-top-alt:11.25pt;margin-right:0cm;margin-bottom:11.25pt;margin-left:0cm">
<span style="font-size:10.0pt;font-family:"Helvetica","sans-serif"">I’m using tempest to validate a deployed cluster, and while we have most things ironed out, I’m seeing a good number (20% or so) of the compute tests fail with the same error:<o:p></o:p></span></p>
<p style="mso-margin-top-alt:11.25pt;margin-right:0cm;margin-bottom:11.25pt;margin-left:0cm">
<span style="font-size:10.0pt;font-family:"Helvetica","sans-serif""> BadRequest: Bad request <o:p></o:p></span></p>
<p style="mso-margin-top-alt:11.25pt;margin-right:0cm;margin-bottom:11.25pt;margin-left:0cm">
<span style="font-size:10.0pt;font-family:"Helvetica","sans-serif""> Details: {'message': 'Multiple possible networks found, use a Network ID to be more specific.', 'code': '400’}<o:p></o:p></span></p>
<p style="mso-margin-top-alt:11.25pt;margin-right:0cm;margin-bottom:11.25pt;margin-left:0cm">
<span style="font-size:10.0pt;font-family:"Helvetica","sans-serif"">The tests that report this error are quite varied, and many of the tests involved don’t actually attempt to exercise the network. Looking through the the bugs in launchpad that refer to this
error, there is some speculation that this is really a bug/feature of the testing suite, but it’s far from definitive.<o:p></o:p></span></p>
<p style="mso-margin-top-alt:11.25pt;margin-right:0cm;margin-bottom:11.25pt;margin-left:0cm">
<span style="font-size:10.0pt;font-family:"Helvetica","sans-serif"">Does anyone have a handle on why this is occurring, and what we can do to remove the errors, be it testing environment setup, or if this is a bug of nova itself? I’m noticing that the testing
process itself creates many objects in the OpenStack database, networks and otherwise, and doesn’t seem to remove them after a test completes successfully or not; is that the issue?<o:p></o:p></span></p>
<p style="mso-margin-top-alt:11.25pt;margin-right:0cm;margin-bottom:11.25pt;margin-left:0cm">
<span style="font-size:10.0pt;font-family:"Helvetica","sans-serif"">Thanks for any insight you can provide,<o:p></o:p></span></p>
