That's all.

I'm not configure [flowclassifier].

If the installation has been successful, then you can check the comment. "Installing neutron-openvswitch-agent script to /usr/local/bin". Then you can find neutron-openvswitch-agent in /usr/local/bin directory. I checked(Installed) networking-sfc stable/mitaka version yesterday.

2017-01-10 19:31:11 -0500 commented answer Using networking-sfc with liberty neutron (not a devstack)

Did you try check ovs-ofctl dump-flows <bridge> -O openflow13 ?

2017-01-10 17:45:55 -0500 commented answer Using networking-sfc with liberty neutron (not a devstack)

Now a day, I don't use devstack. networking-sfc neutron-openvswitch-agent work instead of neutron-openvswitch-agent. liberty version, doesn't worked networking-sfc neutron-openvswitch-agent. so replaced the ovs-agent. (cp /usr/local/bin/neutron-openvswitch-agent /usr/bin/neutron-openvswitch-agent)

2017-01-08 17:30:40 -0500 commented answer Using networking-sfc with liberty neutron (not a devstack)

Yes. I installed OpenStack manually.

But that time... OpenStack networking-sfc version is liberty.

Anyway I installed networking-sfc using python setup.py install command. (not using pip install networking-sfc command)

2016-07-18 20:09:31 -0500 answered a question using network-sfc, packet flow is not as per service chain?

I think your networking-sfc is something wrong.

If you installed using devstack or manual?

If you using manual... Check this link. (https://ask.openstack.org/en/question...)

Did you try delete br-int/br-tun and system reboot?

2016-07-14 01:41:18 -0500 commented answer openstack mitaka on VM, can not ping floatingip of inner guest VM

Oh... T_T

Did you check dhcp_agent.ini file?

If you using dnsmasq-neutron.conf file...

you check dnsmasq_config_file = /etc/neutron/dnsmasq-neutron.conf ?

this line in dhcp_agent.ini file.

2016-07-14 00:04:11 -0500 answered a question openstack mitaka on VM, can not ping floatingip of inner guest VM

I think it's a MTU problem.

If you have dnsmasq-neutron.conf file.

you can edit dhcp-option-force=26,1450 and saved.

If you don't have dnsmasq-neutron.conf file.

you check this link. http://docs.openstack.org/draft/netwo...

Then restart dhcp-agent.

2016-07-12 18:38:18 -0500 commented answer Openstack Installer Public IP of Horizon

Are you using LXC?

Anyway I think you need a IP_FORWARDING.

Check this page http://ubuntuforums.org/showthread.ph...

2016-07-12 18:32:34 -0500 answered a question unable to browse openstack dashboard from chrome browser in ubuntu 14.0.4lts

Just horizon page only? Other pages are OK?

Try to delete your cache in chrome. (delete internet history and cookies ...)

And reconnect horizon.

2016-07-11 18:59:06 -0500 answered a question Unable to reach private network router

Recheck your data network IPs.

and recreate private network. (different CIDR)

the GW is not working?

Is your data network IP and private IP range is same?

If data network IP and private IP range is same, you don't create same ranges private network.

2016-07-11 18:51:20 -0500 answered a question Openstack Installer Public IP of Horizon

Is your single server have a public IP?

I think you have a public IP already.

Did you try connect http://<public_ip>/horizon ?

and checked /etc/nova/nova.conf

novncproxy_base_url = http://<single server="" public="" ip="">:6080/vnc_auto.html

If your network configuration is OK...

you can try add port forwarding.

ex)

iptables -t nat -A PREROUTING -p tcp -i eth0 --dport 80 -j DNAT --to-destination <ip>:80

iptables -A FORWARD -p tcp -d <ip> --dport 80 -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT

(eth0 and IP is yours)

2016-07-04 19:16:02 -0500 answered a question Devstack - Can't create instances?

Did you check nova service or nova agent list? ($ nova service-list)

If the result is good, you check nova hypervisor. ($ nova hypervisor-show)

If the result is good, you check network. (you check physical network and nova configuration file)

2016-06-27 23:44:43 -0500 commented answer Adding new compute nodes

I think you checked all nodes configuration.

You can check last things.

It's database.

You check neutron db - ml2_gre or ml2_vxlan tables.

You can find tunnel_ip.

Then delete tunnel data in table.

But this way is high risk.

https://ask.openstack.org/en/question...

2016-06-27 19:00:54 -0500 commented answer Adding new compute nodes

First you checkd network interface. $ sudo vi /etc/network/interfaces (you check eth0/eth1/eth2)

controller/compute0/compute1 nodes are connected using tunnel. (192.168.15.xx subnet ranges)

Second check ovs interfaces. $ sudo ovs-vsctl show

did you see br-int and br-tun?

2016-06-21 00:58:32 -0500 commented answer Adding new compute nodes

^^

Well did you restart openvswitch agent on compute1?

if you check compute1 configuration.

$ sudo ovs-vsctl del-br br-int

$ sudo ovs-vsctl del-br br-tun

Then reboot compute1.

compute0 and compute1 configuration point is same.

just different thing is ip address. (management ip / TUNNEL IP)

2016-06-20 06:07:20 -0500 commented answer Adding new compute nodes

compute1 configuration.

  • nova.conf

First copy nova.conf in compute0.

Second change my_ip section. (my_ip = 192.168.0.70)

don't comment out rpc_backend=rabbit section.

  • ml2_conf.ini

First copy ml2_conf.ini in compute0.

Second change local_ip section. (local_ip = {TUNNEL IP, 192.168.15.70})

2016-06-20 02:24:15 -0500 commented answer Adding new compute nodes

Oh... you want create instance on choose compute node?

if you create instance to specific compute node, you using nova CLI...

for example $ nova boot --image <uuid> --flavor m1.tiny --key_name test --availability_zone=nova:hostname

if you using horizon you can check instance count (over 2)...

2016-06-19 21:16:10 -0500 answered a question Adding new compute nodes

nova and neutron ip configuration change too.

you check nova.conf my_ip section.

and ml2_conf.ini or openvswitch_agent.ini file check.

Then compute1 service restart. (nova and neutron)

you can check all agent on controller node. (nova service-list / neutron agent-list)

you can find compute1 state.

compute1 configuration.

  • nova.conf

First copy nova.conf in compute0.

Second change my_ip section. (my_ip = 192.168.0.70)

  • ml2_conf.ini

First copy ml2_conf.ini in compute0.

Second change local_ip section. (local_ip = {TUNNEL IP, 192.168.15.70})

2016-06-03 01:34:58 -0500 answered a question how to add multiple compute node ?

If you want OpenStack Mitaka.

http://docs.openstack.org/mitaka/inst...

Or OpenStack Liberty.

http://docs.openstack.org/liberty/ins...

You already installed all-in-one version. So you can installed nova-compute service.

You can do it.

2016-06-01 21:48:24 -0500 answered a question OpenStack Installation

http://docs.openstack.org/liberty/install-guide-ubuntu/neutron.html (http://docs.openstack.org/liberty/ins...)

First install OpenStack liberty step by step.

Install Networking Service...

(Controller Node : Controller+Network Node / Compute Node : Compute Node)

  • Controller Node

1) apt-get install neutron-server neutron-plugin-ml2 \ neutron-plugin-openvswitch-agent neutron-l3-agent neutron-dhcp-agent \ neutron-metadata-agent python-neutronclient conntrack

2) edit agent file (l3_agent.ini / dhcp_agent.ini)

interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver

3) edit ml2 file (ml2_conf.ini)

mechanism_drivers = openvswitch

  • Compute Node

apt-get install neutron-plugin-openvswitch-agent conntrack

The key is neutron-plugin-openvswitch-agent... networking-sfc worked own neutron-openvswitch-agent. So... First stoped neutron-plugin-openvswitch-agent. (sudo service neutron-plugin-openvswitch-agent stop) Second start networking-sfc agent. (sudo python /usr/local/bin/neutron-openvswitch-agent)

My devstack environment is multi node... one is devstack all_in_one and the other is devstack compute. (the version is stable/liberty) https://wiki.openstack.org/wiki/Neutron/ServiceInsertionAndChaining (https://wiki.openstack.org/wiki/Neutr...)

2016-05-20 01:09:56 -0500 commented answer Using networking-sfc with liberty neutron (not a devstack)

I don't know... using devstack(liberty+sfc)... everything is perfect!!! create flow-classifier/port-pair/port-pair-group/port-chain is fine! and dump-flows is very good.

not devstack environment... create flow-classifier/port-pair/port-pair-group/port-chain is seems OK... But I can't see sfc flows.

2016-05-18 23:55:39 -0500 answered a question Using networking-sfc with liberty neutron (not a devstack)

I have a same problem. I solved this problem.

neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini --subproject networking-sfc upgrade head

But something wrong.

ovs-ofclt dump-flows <bridge> -O openflow13

I can't found networking-sfc flow.

[update]---------------------------------

sudo service neutron-openvswitch-agent stop

sudo python /usr/local/bin/neutron-openvswitch-agent

check networking-sfc flow...

Keypoint is networking-sfc ovs agent.

Using networking-sfc ovs agent instead of neutron-plugin-openvswitch-agent.

Thanks to my friend... chi-wook. Jung :)

[update]---------------------------------

git clone https://github.com/openstack/networki... -b stable/liberty pip install -e /home/{user}/networking-sfc

you can find lib file. /usr/local/lib/python2.7/dist-packages/

python setup.py install (in networking-sfc directory)

then you can find neutron-openvswitch-agent file. (/usr/local/bin/)

problem is neutron-sfc driver RPC Call to openvswitch-agent is OK...

But openvswitch-agent is silence...

So...

cp /usr/local/bin/neutron-openvswitch-agent /usr/bin/neutron-openvswitch-agent

that's all
