Re: [Openstack] Install/Enable Quantum lbass (load balancer) feature?

[Eugene Nikanorov]

Hi Jake,

Regarding lbaas in grizzly working on RHEL/Centos - it may be problematic
as host operation system must support network namespaces.
If you do have support for network namespaces then you need to do the
following steps to setup lbaas service in quantum:

1) specify lbaas plugin in quantum.conf:
service_plugins= lbaas_plugin_classpath.
check quantum/plugins/services/agent_loadbalancer/plugin.py for correct
path as currently the name and path has changed.

2) to enable lbaas service in horizon you need to do the following:
add the following piece of code
to horizon/openstack_dashboard/local/local_settings.py :

OPENSTACK_QUANTUM_NETWORK = {
'enable_lb': False
}

3) start quantum-lbaas-agent on the host providing quantum.conf and
lbaas-agent.ini. lbaas-agent.ini should reflect core plugin configuration
(should have proper interface driver)

Note that if host os has no namespace support, all of above will work (e.g.
REST API will be functional), but you would not be able to deploy
loadbalancer as lbaas agent can only work with namespaces.

Thanks,
Eugene.

Do you have haproxy package installed on your host?

Re: [Openstack] Install/Enable Quantum lbass (load balancer) feature?

[Eugene Nikanorov]

Jake, haproxy.cfg is created by lbaas agent when you deploy an instance.
Are you sure your host os has namespace support?

Re: [Openstack] Install/Enable Quantum lbass (load balancer) feature?

[Eugene Nikanorov]

use_namespaces has no effect, lbaas agent in grizzly always relies on
namespace support.

Could you execute the failing command manually?
That needs to be done after you create a vip for the pool.
The command should look like this:
sudo quantum-rootwrap /etc/quantum/rootwrap.conf ip netns exec
qlbaas-e10951cd-4cca-4ba4-acc0-0ccde6817029 haproxy -f /var
/lib/quantum/lbaas/e10951cd-4cca-4ba4-acc0-0ccde6817029/conf -p
/var/lib/quantum/lbaas/e10951cd-4cca-4ba4-acc0-0ccde6817029/pid

 should be replaced with actual
pool_id
Could you also verify that path and file /lib/quantum/lbaas/e10951cd-
4cca-4ba4-acc0-0ccde6817029/conf exist?

Thanks,
Eugene.

Re: [Openstack] Fw: [openstack-dev] [Quantum]How to contribute LBaas driver?

[Eugene Nikanorov]

Copying my previous reply:

Hi Hu Yanrui,

Thanks for your interest.
The links in previous email are correct, please use them to familiarize
yourself with development process.
Make sure to use upstream version of neutron when developing your driver.
You can post your code to review (you also can post draft version
https://wiki.openstack.org/wiki/Gerrit_Workflow ),  and we'll try to
provide some advice/support.

Thanks,
Eugene.

Re: [Openstack] Fw: [openstack-dev] [Quantum]How to contribute LBaas driver?

[Eugene Nikanorov]

Upstream version means the latest code in master branch of
https://github.com/openstack/neutron.git
Currently it's Havana release cycle and there was a lot of changes,
including changes in lbaas service structure, so in order to contribute the
driver (e.g. commit your driver to upstream), you need to make it compliant
with current state of the code.

Thanks,
Eugene.

Re: [Openstack] Need to change Network node

[Eugene Nikanorov]

Hi,

How about moving L3 & dhcp agents as well as other networking services to
other node?
Multiple nodes having L3 and dhcp agents are supported since Grizzly. So
you don't need to have dedicated network node for these agents.
You'll probably need to recreate (or reschedule) routers if you have any,
but it seems like your VMs should continue working and have connectivity
(within tenant private network)

Thanks,
Eugene.

Re: [Openstack] Need to change Network node

[Eugene Nikanorov]

I don't think you need to recreate tenant subnet.
First of all it probably will not be possible because of VMs connected to
existing one.
Secondly, there is no need as moving L3 and dhcp agents should not affect
existing subnet for already running VMs

Thanks,
Eugene.

Is it possible that on both nodes your agents have the same hostname in
their conf files?

Re: [Openstack] [neutron] Connection to neutron failed: Maximum attempts reached

[Eugene Nikanorov]

Can you check that neutron server is actually running?
It should create a listening tcp socket on the port 9696.
Can you also look at Neutron server logs? If there is some misconfiguration
and Neutron server fails to start, logs could give a hint about what is
wrong.

Thanks,
Eugene.

Re: [Openstack] Multiple service_plugins in neutron.conf, is that possible?

[Eugene Nikanorov]

Hi Rami,

Yes, service_plugins is a list of class paths of service plugins. So you're
able to specify say lbaas, fwaas and vpn plugins.
The separator is comma.

Thanks,
Eugene.

Re: [Openstack] [Neutron] Unable to create Floating IPs.

[Eugene Nikanorov]

What plugin are you using?
Can you post neutron.conf to paste.openstack.org?
>From the extension list it's clear that router extension is missing (it's
the extension  that allows you to create floating ips)

Thanks,
Eugene.

Re: [Openstack] [Neutron] Unable to create Floating IPs.

[Eugene Nikanorov]

Could you please post a portion of neutron-server logs to
paste.openstack.org?
neutron.conf seems to be correct: l3 plugin is present, so router extension
should be supported.
In first several hundreds of lines should contain loading of router
extension and why it was or was not loaded.

Thanks,
Eugene.

Re: [Openstack] [Neutron] 404 response from Neutron LB API

[Eugene Nikanorov]

Hi Guillermo,

Could you specify which neutron commands return 404?
Can you also provide server-side logs when you see 404 from neutron server?
Also, please post your neutron.conf file to paste.openstack.org.

Thanks,
Eugene.

Re: [Openstack] [Neutron] 404 response from Neutron LB API

[Eugene Nikanorov]

I see the following in your neutron.conf:

# Advanced service modules
service_plugins = neutron.services.loadbalancer.plugin.LoadBalancerPlugin

#Next service added to allow VPN use
service_plugins = neutron.services.vpn.plugin.VPNPlugin


service_plugins is a list option so plugin paths should be
comma-separated as follows:

service_plugins =
neutron.services.vpn.plugin.VPNPlugin,neutron.services.loadbalancer.plugin.LoadBalancerPlugin


Thanks,

Eugene.

Re: [Openstack] LbaaS VIP is not accessible from outside

[Eugene Nikanorov]

Hi Nick,

What you are describing is the by-design behavior: HAProxy provider creates
VIP on the tenant network and by default it is accessible only from within.
Assigning floating IP to VIP's port is a manual step needed in order to
provide external visibility.

Thanks,
Eugene.

Re: [Openstack] LbaaS VIP is not accessible from outside

[Eugene Nikanorov]

I don't quite understand, both floating ip and vip seem to have
192.168.1.100 address which is incorrect.

Could you please post the output of the following commands:
lb-vip-show c756a3d3-c62e-4fe5-8c92-3fdf1da4b68d
port-show 63726b11-f226-4765-9736-c3dc697fe221
floatingip-show  f01b1c8c-6168-4860-a7f0-5a60d5e958db

Thanks,
Eugene.

Re: [Openstack] LbaaS VIP is not accessible from outside

[Eugene Nikanorov]

That looks strange. Floating ip association is not lbaas-specific.
Can you do the following:
1) create another floating ip and associate it with vip port and see if it
works
2) create another floating ip and associate it with another port (some
instance) and see if it works.

I assume that (1) and (2) both should either fail or work.
If (1) is not working still for some reason, then logs from L3 agent could
shed some light on what is happening.

Thanks,
Eugene.

Re: [Openstack] [openstack-dev] Tempest Testcases for ML2 Mechanism drivers - Help

[Eugene Nikanorov]

Trinath,

Tempest tests should be backend-agnostic, so specific tests for your
mechanism driver is not needed.
You need specific testing environment for that which will run tempest tests
against a deployment with mechanism drivers you want to test. See also:
http://ci.openstack.org/third_party.html

Thanks,
Eugene.

Re: [Openstack] [Neutron] LBaaS not working after Grizzly -> Havana update (DB error)

[Eugene Nikanorov]

Hi Jonathan,

It really looks as migration issue. I wonder how did you perform the
migration.
Devstack usually runs migration during the setup and everything works fine
with the current code.

Could you provide more details about how you run the migration.

Thanks,
Eugene.

Re: [Openstack] LBaaS solution for eleminate SPOF is required

[Eugene Nikanorov]

Hi Heiko,

That kind of failover mechanism was on our roadmap:
https://review.openstack.org/#/c/59743/
However right now the work is deferred as we're discussing general design
of HA feature.
I can't guarantee that will be something included in Juno, but there's
strong demand for this feature so it has high priority on our list.

Thanks,
Eugene.

Unfortunately with the current state of code it's not possible.

Wait for the new lbaas version where this should be implemented with

Why not to use Mirantis Fuel?

It can deploy Openstack in HA mode. HA is implemented via pacemaker there.

Re: [Openstack] [Fuel] network-template to create multiple external networks

[Eugene Nikanorov]

Michaël,

If you're planning to use external network through the NIC which is also
used by tenant networks, then you don't need anything additional from Fuel.
After deployment you will need to create external network as provider
network, specifying physnet corresponding to eth1 and segmentation id to be
215.

The process of configuring multiple external networks is described here:
http://blog.oddbit.com/2014/05/28/multiple-external-networks-wit/
Depending on how external networks are physically configured you (or Fuel)
may or may not need to perform some steps of what is described there.
But you certainly need to reconfigure L3 agents, which Fuel will not do for
you.

Thanks,
Eugene.

Re: [Openstack] [Fuel] network-template to create multiple external networks

[Eugene Nikanorov]

br-floating is just a name that corresponds to a default public network
provisioned by fuel.
You don't need to delete it, especially if you want existing external
network to work properly.

Physnet is essentially an alias of the physical bridge and is used when
creating provider network.

Thanks,
Eugene.

Re: [Openstack] [Openstack-operators] UDP Buffer Filling

[Eugene Nikanorov]

John,

multiqueue support will require qemu 2.5+
I wonder why do you need this feature. It only will help in case of a
really huge incoming pps or bandwidth.
I'm not sure udp packet loss can be solved with this, but of course better
try.

my 2c.

Thanks,
Eugene.
