[Rdo-list] neutron-openvswitch-agent without ping lost

[Chris]

Hello,

 

We made some changes on our compute nodes in the
"/etc/neutron/neutron.conf". For example qpid_hostname. But nothing what
effects the network infrastructure in the compute node.

To apply the changes I think we need to restart the
"neutron-openvswitch-agent" service.

 

By restarting this service the VM gets disconnected for around one ping, the
reason is the restart causes recreation of the int-br-bond0 and phy-br-bond0
interfaces:

ovs-vsctl: ovs|00001|vsctl|INFO|Called as /usr/bin/ovs-vsctl --timeout=10 --
--may-exist add-br br-int

ovs-vsctl: ovs|00001|vsctl|INFO|Called as /usr/bin/ovs-vsctl --timeout=10 --

ovs-vsctl: ovs|00001|vsctl|INFO|Called as /usr/bin/ovs-vsctl --timeout=10 --
--may-exist add-port br-bond0 phy-br-bond0

 

Is there a way to apply this changes without loose pings?

 

Cheers

Chris
