Hi Akshay No it didn‘t quite work, after editing the configuration file /etc/network/interfaces accordingly to those instructions. Did restart the networking service /etc/init.d/networking restart Afterwards, I‘m not able to ping the default gateway.

Define interface br-ex, give it static IP same as em3. 2. Add em3 to promiscuous mode. Your interfaces file should look something like: auto br-ex iface br-ex inet static address X.X.X.X netmask X.X.X.X network X.X.X.X dns-nameservers X.X.X.X dns-search example.com<http://example.com> gateway X.X.X.X auto em3 iface em3 inet manual up ifconfig $IFACE 0.0.0.0 up up ip link set $IFACE promisc on down ip link set $IFACE promisc off down ifconfig $IFACE down Hope this helps! -- Regards, Akshay On Wed, Mar 25, 2015 at 4:00 PM, Yngvi Páll Þorfinnsson <[email protected]<mailto:[email protected]>> wrote: Hi Andreas Yes you're absolutely correct about this, when I use ifconfig em3 0 ifconfig br-ex 172.22.17.12/24<http://172.22.17.12/24> I can ping the default gateway 172.22.7.1 But, how would you configure this permanently? i.e. how would you edit the network configuration file: /etc/network/interfaces To make this a permanent configuration?

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<http://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]<mailto:[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.
