Fixed In Version: | openstack-neutron-2013.2.4-1.el6ost | Doc Type: | Bug Fix |
Doc Text: |
In some cases, an instance's TAP interface was set and reset too rapidly by the hypervisor to be caught in the OVS neutron-agent loop, and as a result its VLAN tag was not reset. This could occur, for example, on an instance reboot. As a result, the instance lost network connectivity.
This has been fixed so that every time an interface loses its VLAN tag, the OVS Neutron agent catches it and reconfigures the interface. As a result instances do not lose network connectivity after reboot.

The fix was included in all Icehouse based RHEL-OSP releases. Which release have you tested against? If you want to target the fix to Havana too, please set Target appropriately. Thanks for looking at this. The customer in the attached case is hitting this on RHEL-OSP 4. I have set the target to the correct release. ON RHEL 6.6 [root@puma46 ~]# rpm -qa | grep neutron openstack-neutron-openvswitch-2013.2.4-5.el6ost.noarch python-neutron-2013.2.4-5.el6ost.noarch openstack-neutron-ml2-2013.2.4-5.el6ost.noarch python-neutronclient-2.3.4-1.el6ost.noarch openstack-neutron-2013.2.4-5.el6ost.noarch after soft reboot cirros VM is still able to ping google (8.8.8.8) Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
