Hello fellow Openstackers-

I have a quick question regarding routed provider networks.  I am
looking at this
page: 
https://docs.openstack.org/ocata/networking-guide/config-routed-networks.html

I configured the controller as stated in the docs, however this line is
somewhat vaugue:

"


  Network or compute nodes¶
  


  * Configure the layer-2 agent on each node to map one or more segments
to the appropriate physical network bridge or interface and restart
the agent."


Which file am I editing on the compute nodes to answer the above question?
If you are using OpenVSwitch agent, then on compute/network node you 
should modify:

/etc/neutron/plugins/ml2/openvswitch_agent.ini
/etc/neutron/plugins/ml2/ml2_conf.ini




Thank you,
A

Re: [Openstack] controller redundancy

2017-04-12 Thread Yura Poltoratskiy 

Hi,

I do not familiar with mirantis os 9, but in general there is an 
architecture when vm can be still accessible even without controller.


Also, there is a guide for HA deployment, here are for controllers in 
particular - https://docs.openstack.org/ha-guide/controller-ha.html

Hi guys,
I'm new to openstack.
Installed mirantis os 9,
If one of controllers goes down - vm machines are not accesible, I
though openstack supposed to work even if one controller is alive

Any thoughts?

Re: [Openstack] [Neutron] Need L2 Connectivity between the extra two nics between the VMs created on OpensStack

2017-03-17 Thread Yura Poltoratskiy 
If I understand correctly, all I need to do is to create a network (via 
dashboard or cli), to create two ports and to attach the ports to you 
VMs. After all this steps you will have situation like you two servers 
connected through a switch or by wire directly (which is the same). This 
is in general.


I don't know about your deployment scenario, but if you were using 
ansible I believe that there is basic network functionality already.

What kind of cable? What protocol will be carried over it?

Traffic between VMs on different hosts needs to be encapsulated by a
protocol like GRE or VXLAN to carry it over the real network so that
imposes some limitations on emulating a 'direct wire'.

If you need to carry some other l2 protocol between two VMs, I
suggest that you just establish and L2TP connection between the
hypervisors.

What type of L2 communication do they need to do? If it's
ethernet, then just attaching two ports to a network using
one of the reference ML2 drivers (i.e. OVS or LinuxBridge)
will give you L2 ethernet connectivity via virtual switches.

If you want two VMs connected via a direct connect that
passes arbitrary frames directly without switching so you
can use non-ethernet protocols, then I don't believe any of
the plugins support a model like that.

Hi,

I have installed openstack using ansible on Ubuntu 16.04
Server.
I am able to successfully create VMs and launch
instances however the requirement is to add one extra
nic on both VMs(default is only once nic) so as the
extra nics are connected as if they are physically
connected via a wire i.e. L2 connectivity.

Please let me know your suggestions.


Thanks

Re: [Openstack] Disable Mac and IP spoof protection

2017-03-09 Thread Yura Poltoratskiy 

Hi.

We have OpenVZ as an instance, so there are many ip addresses on the 
instance. The only thing that I've done was disabling PortSecurity.


If I'm correct, there is no way to update port for disabling PortSec, 
one have to delete port and to create a new with 
"--port-security-enabled=False".


09.03.2017 03:18, Sterdnot Shaken пишет:

Is there a way to disable Mac and IP spoof protection for just 1 instance?


I want to run an L2TP server on that instance so I can merge a remote
(over the internet) broadcast domain at a customer site with a Openstack
tenant network. To do this though, I need Openstack to allow n number of
MAC addresses and IP's to be allowed out the instances port, which
IP/MAC spoofing is preventing...


Any ideas?


Thanks in advance!!

[Openstack] nova drop port after VMs was evacuated through host-evacuate and failed compute was started again

2016-07-18 Thread Yura Poltoratskiy 
Hello.

Recently my compute was failed and I run host-evacuate, the VMs was started
properly, but after failed compute was started again, nova was dropped
ports of VMs which was evacuated with next log in nova-compute.log:

2016-07-15 03:29:59.013 4617 INFO nova.network.neutronv2.api
[req-c76160e4-4a29-4f78-85e4-ab5b1dc08dd4 - - - - -] [instance:

46cae1d0-b894-419f-ac8f-56c85c74b184 from network info_cache is no longer
associated with instance in Neutron. Removing from network info_cache.

Is this a bug?

Which is the right scenario to properly boot failed compute?

[Openstack] AMQP server is unreachable / AMQP server closed the connection. Check login credentials

2016-03-24 Thread Yura Poltoratskiy 
Hello,

I am a new to OpenStack. I am deploying from scratch and my architecture as
such:
2 servers - computes
3 servers - controllers
3 servers - SAN
1 server - network

On every controller node I have created lxc contrainer for every service,
so I have 3 containers for every service, and each container live on bare
server.

Operation system - Ubuntu 14.04 with cloud-archive:liberty on each
server/container and there are no firewall enabled.

Messages server is RabbitMQ, with I have deployed step-by-steb from this
guide:
http://docs.openstack.org/ha-guide/controller-ha-rabbitmq.html#rabbitmq-services

My first try to launch instance was failed. From the log I assume that the
problem is near the messages server. Here is some log.
