Hi shihanzhang / Alioune , *your kernel (check with uname -r ) should support OVS version , below table compare kern*el versions and corresponding Open vSwitch release support
| Open vSwitch | Linux kernel |:------------:|:-------------: | 1.4.x | 2.6.18 to 3.2 | 1.5.x | 2.6.18 to 3.2 | 1.6.x | 2.6.18 to 3.2 | 1.7.x | 2.6.18 to 3.3 | 1.8.x | 2.6.18 to 3.4 | 1.9.x | 2.6.18 to 3.8 | 1.10.x | 2.6.18 to 3.8 | 1.11.x | 2.6.18 to 3.8 | 2.0.x | 2.6.32 to 3.10 | 2.1.x | 2.6.32 to 3.11 | 2.3.x | 2.6.32 to 3.14 | 2.4.x | 2.6.32 to 4.0 | 2.5.x | 2.6.32 to 4.3 http://openvswitch.org/support/dist-docs/FAQ.md.txt ( ### Q: What Linux kernel versions does each Open vSwitch release work with?) I installed SFC with OVS 2.4.0 and 2.5.0 and not seen any issue Please check SFC wiki for installation guidelines : https://wiki.openstack.org/wiki/Neutron/ServiceInsertionAndChaining Thanks., Mohankumar.N On Tue, Jun 7, 2016 at 1:46 PM, shihanzhang <ayshihanzh...@126.com> wrote: > Hi Alioune and Cathy, > For devstack on ubuntu14.04, the default ovs version is 2.0.2, so > there was the error as Alioune said. > Do we need to install speical ovs version in networking-sfc devstack > plugin.sh? > > > > > > 在 2016-06-07 07:48:26，"Cathy Zhang" <cathy.h.zh...@huawei.com> 写道： > > Hi Alioune, > > > > Which OVS version are you using? > > Try openvswitch version 2.4.0 and restart the openvswitch-server before > installing the devstack. > > > > Cathy > > > > *From:* Alioune [mailto:baliou...@gmail.com] > *Sent:* Friday, June 03, 2016 9:07 AM > *To:* openstack-dev@lists.openstack.org > *Cc:* Cathy Zhang > *Subject:* [openstack-dev][neutron][SFC] > > > > Probleme with OpenStack SFC > > Hi all, > > I've installed Openstack SFC with devstack and all module are corretly > running except the neutron L2-agent > > > > After a "screen -rd", it seems that there is a conflict between l2-agent > and SFC (see trace bellow). > > I solved the issue with "sudo ovs-vsctl set bridge br > protocols=OpenFlow10,OpenFlow11,OpenFlow12,OpenFlow13" on all openvswitch > bridge (br-int, br-ex, br-tun and br-mgmt0). > > I would like to know: > > - If someone knows why this error arrises ? > > - is there another way to solve it ? > > > > Regards, > > > > 2016-06-03 12:51:56.323 WARNING > neutron.plugins.ml2.drivers.openvswitch.agent.ovs_neutron_agent > [req-1258bbbc-7211-4cfd-ab7c-8b856604f768 None None] OVS is dead. > OVSNeutronAgent will keep running and checking OVS status periodically. > > 2016-06-03 12:51:56.330 DEBUG > neutron.plugins.ml2.drivers.openvswitch.agent.ovs_neutron_agent > [req-1258bbbc-7211-4cfd-ab7c-8b856604f768 None None] Agent rpc_loop - > iteration:4722 completed.
