Re: [Rdo-list] Compute Node without firewall (iptables) and Linux bridge

Hello, 1) we just don't need it, we are using the provider network which includes hardware firewalls. 2) We have huge performance problems regarding TCP_CRR / TCP_RR. The OpenStack VMs can deal just half of TCP connections per second compared to our bare metal installations. Throughput (10Gbit NIC) is fine though. Specs VMs and bare metal are of course equal (RAM, Cores, etc.) Did a lot of testing regarding the performance issues, it happens "after" the both (br-int/br-ex) openvswitches. Upgraded ovs to version 2.3 just fyi.

Can you elaborate on reasons to disable it? Of course it sounds a bit not optimal, but do you have any performance concerns that you try to address in this way? > We using the RDO Icehouse release. > Here is the configuration in the compute node: > #/etc/neutron/plugin.ini > [securitygroup] > #firewall_driver = > neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver > firewall_driver = neutron.agent.firewall.NoopFirewall > # enable_security_group = True > enable_security_group = False > #/etc/nova/nova.conf > firewall_driver = nova.virt.firewall.NoopFirewallDriver > #security_group_api = neutron > #/etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini > [securitygroup] > firewall_driver = neutron.agent.firewall.NoopFirewallDriver > enable_security_group = False > The firewall seems to be disabled but the bridge and the interfaces > are being still created. > I found an older post about it: > http://lists.openstack.org/pipermail/openstack/2014-May/007079.html > But changing ?portbindings.OVS_HYBRID_PLUG" from a hard-coded "True" > to "False" didn?t change anything. > Please advise! > Cheers > Chris > _______________________________________________ Rdo-list mailing list > Rdo-list(a)redhat.com https://www.redhat.com/mailman/listinfo/rdo-list _______________________________________________ Rdo-list mailing list Rdo-list(a)redhat.com https://www.redhat.com/mailman/listinfo/rdo-list -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.22 (Darwin) iQEcBAEBCgAGBQJUUR4LAAoJEC5aWaUY1u57uQgIAIUWQaBW9HshqnJiUSgsuH/5 9a7p0fZJW2JwhZ00TFq6K4njjPV2xnHKQrae1MbEduOD0SwpcXlzR2dXbOXLx8Mm swWJim87X4uKNnK2c6MD1WB7wB1d3yVS4SurgS7/DFPyQD1ysHq4FM/XyWSNGcy/ n2GW5TMNokFe6gLXU9r/yDQlsnQsARmK5wnZ63VXHl3S9qnH2gnLPsuZh7X3FUV8 RAsiA9IR2RqiBamS3oGssgP0zIxkNRUwS+muZx//dwRr1NkqZMBNrkdN2t/PZLnD MBwTX5e8uwJ1Jn5mQB7Wy9n1NdkNTPxZT2R5fBU70UVn8qJbXVzzyif7h4we0zU= =VUIE -----END PGP SIGNATURE-----
