Hi Yngyi, this absolutely makes sense.
As soon as you add a port to a bridge (doesn't matter if linux- or ovs-bridge) it cannot be used as ip interface anymore. What you have to do after you've added this interface to br-ex, you have to "move up" the ip address to the br-ex. e.g. > ifconfig em3 0 > ifconfig br-ex 172.22.17.12/24 And you should be fine Hope this helps! -- Andreas (irc: scheuran) On Tue, 2015-03-24 at 14:31 +0000, Yngvi Páll Þorfinnsson wrote: > Hi, > > I‘ll just give you an update on this „problem“. > > I can go back and ping the default gateway etc. > > if I go back one step, and delete the port config for br-ex > > > > ovs-vsctl del-port br-ex em3 > > > > best regards > > Yngvi > > > > From: Yngvi Páll Þorfinnsson > Sent: 23. mars 2015 16:45 > To: [email protected] > Subject: [Openstack] openvswitch configuraion > > > > > Hi, > > I‘m trying to configure neutron on the networking node. > > > > My problem is: > > The 3rd interface is somehow not working after I configure > openvswitch. > > > > I‘m using the manual > > „OpenStack Installation Guide for Ubuntu 14.04“ - Juno > > Everything has gone well until I reached the configuration of the Open > vSwitch (OVS)mechanism. > > i.e. > > To configure the Modular Layer 2 (ML2) plug-in > > The ML2 plug-in uses theOpen vSwitch (OVS)mechanism (agent) to build > the virtual networking > > framework for instances.
