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
and line 233, in _define_filter
Version-Release number of selected component (if applicable):
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
Instance's status is 'SHUTOFF'
Instance's status should be 'ACTIVE'
Updating libvirt* packages from rawhide did not help.
Downgrading the libvirt* packages while ignoring dependency problems from fedora 20 repository (version 220.127.116.11-1.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bug reports from releases that are no longer maintained.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'
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no longer maintained, which means that it will not receive any further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
Thank you for reporting this bug and we are sorry it could not be fixed.
