Created attachment 955700 [details] Extract from nova-compute.log Description of problem: After upgrading to Fedora 21, the openstack instances failed to spawn. The error message: Error: operation failed: filter 'nova-no-nd-reflection' already exists with uuid 728f13cf-f1a9-4e0e-add7-357b93d052ee The exception is raised by File "/usr/lib64/python2.7/site-packages/libvirt.py", line 4004, in nwfilterDefineXML if ret is None:raise libvirtError('virNWFilterDefineXML() failed', conn=self) The reason appears to be File "/usr/lib/python2.7/site-packages/nova/virt/libvirt/firewall.py", line 213, in _ensure_static_filters self._define_filter(self.nova_no_nd_reflection_filter) and line 233, in _define_filter self._conn.nwfilterDefineXML(xml) Version-Release number of selected component (if applicable): How reproducible: Every time. I uninstalled openstack packages, cleared the data and tried affresh. It still fails. Steps to Reproduce: 1. nova start <instance name> 2. nova list 3. Actual results: Instance's status is 'SHUTOFF' Expected results: Instance's status should be 'ACTIVE' Additional info: Updating libvirt* packages from rawhide did not help. Downgrading the libvirt* packages while ignoring dependency problems from fedora 20 repository (version 1.1.3.6-1.fc20.x86_64) seems to resolve the problem.
This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '21'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 21 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 21 changed to end-of-life (EOL) status on 2015-12-01. Fedora 21 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
