Sean, Andreas-

Sorry I missed Andres’ message earlier in December about retiring astara. 
Everyone is correct that development stopped a good while ago.  We attempted in 
Barcelona to find others in the community to take over the day-to-day 
management of the project. Unfortunately, nothing sustained resulted from that 
session. 

I’ve intentionally delayed archiving the repos because of background 
conversations around restarting active development for some pieces bubble up 
from time-to-time.  I’ll contact those I know were interested and try for a 
resolution to propose before the PTG.

Would it be possible to move the Astara fish bowl session to Thursday morning?  
It would avoid the conflict with Tacker.  We’re hoping to see where the teams 
could cooperate across projects in the future.

[openstack-dev] TC candidacy

2015-04-22 Thread Mark McClain
All-

I'd like to announce my candidacy to continue serving on the Technical 
Committee.


Platform
—
OpenStack is a growing community comprised of many parts and we we must view 
ourselves as one unit. As a TC member, I will continue to place the interests 
of the larger community over those of those of individual projects.

There are several key areas I'd like to see the TC focus:

Development
  The Technical Committee should serve as a high level forum to facilitate 
defining cross project technical and procedural requirements. While many of our 
programs share commonalities, there are still too many differences in policies 
and technical decisions. The addition of cross project specifications is a step 
towards unifying the development process and design standards within our 
community.  As we accept more projects under the new governance model, the TC 
should work to facilitate developer mobility across projects by promoting best 
practices.  Increased mobility will strengthen our community as it helps to 
prevent silos. Reviews are an another area the TC should focus on during the 
upcoming cycle. The TC should review and work with projects to improve the 
contributor and reviewer experience when contributing to projects both big and 
small.

Cross Project Communication
  Our codebase has grown significantly over the years and a contributor must 
invest significant time to understand and follow every project; however many 
contributors have limited time must choose a subset of projects to direct their 
focus.  As a result, it becomes important to employ cross project communication 
to explain major technical decisions, share solutions to project challenges 
that might be widely applicable, and leverage our collective experience.  The 
TC should seek new ways to facilitate cross project communication that will 
enable the community to craft improvements to the interfaces between projects 
as there will be greater familiarity between across the boundary.

Unified Experience
  For OpenStack to be successful we must strive to provide a unified experience 
for both users and deployers. During the previous cycles we have made progress 
in this area, but there is still work to be completed. When visiting user 
groups, a common thread during discussion is the installation experience. The 
TC should identify common installation configurations and work with projects to 
optimize installation and upgrades.  Equally important is the users. The TC 
should work to promote and support projects such the OpenStack client and SDK 
which aim to provide users with tools that are well maintained, documented and 
easy to use. Our community has invested significant effort to improve this 
experience and this should remain a focus going forward.


About Me
——
I have served on the Technical Committee for last two years and I am a former 
PTL. Believing that OpenStack is a unified community, I have contributed code 
and reviews to many of our projects since Sent from my iPad

We have built a very special open community through the contributions of many.  
These contributions have powered our phenomenal growth and I'm excited about 
our future!

Thanks,
mark

 ​Just adding my support to the very hard thing that Mike is doing here.  As 
 mentioned discussions and warnings have gone on ad nauseum over the last 
 year.  I may not agree with some of the wording or depictions, ​and I 
 certainly am empathetic here; but the fact is this has been a year long 
 process that was communicated, discussed and help provided.  NOTE this 
 started at the summit in Atlanta!!!
 
 CI can be hard, the work of a lot of people in Cinder, the Infra team and 
 others have made it a lot easier.  People have also spent countless hours 
 writing code for this, setting up their own systems and helping others out 
 via IRC and even a dedicated weekly meeting as well as a time slot every week 
 in Cinders meeting.  
 
 If the reasons were different than my data center went offline or I can't 
 host a public web server I might have a different opinion.  But I have a 
 really hard time with this sort of thing coming from companies the size and 
 scale of Microsoft, NetApp and Oracle.
 
 Anyway, I do feel bad but not as bad as I'd feel for everybody that worked 
 their butts off on this whole topic for the last year if we turn around and 
 punt it again.
 
 John
 

Echoing both Thierry and John.  I support Mike’s decision to enforce the 
requirement. Maintaining drivers in the tree comes with responsibilities to the 
community and 3rd party CI is one of the them.  Mike enforcing this requirement 
was the right action even if a hard one to take.

You’re right that the Mako dependency is really a side effect from Alembic.  We

 First of all, I'm removing Sumit Naiksatam from neutron-core. Sumit has been

 thoughtful reviews in the future, we can look at getting him back as a 
 Neutron core reviewer. But for now, his stats indicate he's not reviewing at 
 a level consistent with the rest of the Neutron core reviewers.
 
 As part of the change, I'd like to propose Doug Wiegley as a new Neutron core 
 reviewer. Doug has been actively reviewing code across not only all the 
 Neutron projects, but also other projects such as infra. His help and work in 
 the services split in December were the reason we were so successful in 
 making that happen. Doug has also been instrumental in the Neutron LBaaS V2 
 rollout, as well as helping to merge code in the other neutron service 
 repositories.
 
 I'd also like to take this time to remind everyone that reviewing code is a 
 responsibility, in Neutron the same as other projects. And core reviewers are 
 especially beholden to this responsibility. I'd also like to point out that 
 +1/-1 reviews are very useful, and I encourage everyone to continue reviewing 
 code even if you are not a core reviewer.
 
 Existing neutron cores, please vote +1/-1 for the addition of Doug to the

 It's been a week, and Doug has received plenty of support. Welcome to the 
 Neutron Core Review team Doug!
 

Welcome Doug!

 I do realize that Nova takes a different approach to *some* resources,

 End of the day, it's probably just a personal preference whether names should 
 be unique to a tenant/user or not.
 
 Maru had asked me my opinion on whether names should be unique and I answered 
 my personal opinion that no, they should not be, and if Neutron needed to 
 ensure that there was one and only one default security group for a tenant, 
 that a way to accomplish such a thing in a race-free way, without use of 
 SELECT FOR UPDATE, was to use the approach I put into the pastebin on the 
 review above.
 

I agree with Jay.  We should not care about how a user names the resource.  
There other ways to prevent this race and Jay’s suggestion is a good one.

[openstack-dev] [tc][neutron] Proposal to split Neutron into separate repositories

2014-11-18 Thread Mark McClain
All-

Over the last several months, the members of the Networking Program have been 
discussing ways to improve the management of our program.  When the Quantum 
project was initially launched, we envisioned a combined service that included 
all things network related.  This vision served us well in the early days as 
the team mostly focused on building out layers 2 and 3; however, we’ve run into 
growth challenges as the project started building out layers 4 through 7.  
Initially, we thought that development would float across all layers of the 
networking stack, but the reality is that the development concentrates around 
either layer 2 and 3 or layers 4 through 7.  In the last few cycles, we’ve also 
discovered that these concentrations have different velocities and a single 
core team forces one to match the other to the detriment of the one forced to 
slow down.

Going forward we want to divide the Neutron repository into two separate 
repositories lead by a common Networking PTL.  The current mission of the 
program will remain unchanged [1].  The split would be as follows:

Neutron (Layer 2 and 3)
- Provides REST service and technology agnostic abstractions for layer 2 and 
layer 3 services.

Neutron Advanced Services Library (Layers 4 through 7)
- A python library which is co-released with Neutron
- The advance service library provides controllers that can be configured to 
manage the abstractions for layer 4 through 7 services.

Mechanics of the split:
- Both repositories are members of the same program, so the specs repository 
would continue to be shared during the Kilo cycle.  The PTL and the drivers 
team will retain approval responsibilities they now share. 
- The split would occur around Kilo-1 (subject to coordination of the Infra and 
Networking teams). The timing is designed to enable the proposed REST changes 
to land around the time of the December development sprint.
- The core team for each repository will be determined and proposed by Kyle 
Mestery for approval by the current core team.
- The Neutron Server and the Neutron Adv Services Library would be co-gated to 
ensure that incompatibilities are not introduced.
- The Advance Service Library would be an optional dependency of Neutron, so 
integrated cross-project checks would not be required to enable it during 
testing.
- The split should not adversely impact operators and the Networking program 
should maintain standard OpenStack compatibility and deprecation cycles.

This proposal to divide into two repositories achieved a strong consensus at 
the recent Paris Design Summit and it does not conflict with the current 
governance model or any proposals circulating as part of the ‘Big Tent’ 
discussion.

 Doug

We had considered having a standalone REST service, but the Advance Services 
need a level of integration with Neutron that is more than REST and RPC can 
provide.  So the initial plan is to have the operator configure the Neutron 
REST service to load the appropriate Advance Service controller modules.  This 
would enable the operators to continue to deploy a single endpoint and preserve 
existing user tools.

The integration interface would be formalized as part of the current 
refactoring work being completed during the Kilo cycle.

Re: [openstack-dev] [neutron] Limitation of permissions on modification some resources

2014-09-29 Thread Mark McClain

 Hi All,
 
 I started working on the the https://bugs.launchpad.net/neutron/+bug/1339028
 and realized that we have the same issue with other connected resources in 
 Neutron.

The is a bug in how we’re implementing the logic to manage routes on the router 
instance in the l3-agent implementation.  There are other implementations of 
the logical router that do not need this restriction. 

 
 The problem is that we have API for the modification of any resources without
 limitations, for example, we can modify Router IP and connected to this subnet
 VMs never will know about it and lose the default router. The same situation
 with routes and IP for DHCP/DNS ports.
  
 https://bugs.launchpad.net/neutron/+bug/1374398
 https://bugs.launchpad.net/neutron/+bug/1267310

I don’t see any of these as a bug.  If tenant wants to make changes to their 
network (even ill advised ones), we should allow it.  Restricting these API 
operations to admin’s means we’re inhibiting users from making changes that 
could be regular maintenance operations of a tenant.

Re: [openstack-dev] [neutron] [IPv6] New API format for extra_dhcp_opts

2014-09-26 Thread Mark McClain

On Sep 26, 2014, at 2:39 AM, Xu Han Peng pengxu...@gmail.com wrote:

 Currently the extra_dhcp_opts has the following API interface on a port:
 
 {
 port:
 {
 extra_dhcp_opts: [
 {opt_value: testfile.1,opt_name: bootfile-name},
 {opt_value: 123.123.123.123, opt_name: tftp-server},
 {opt_value: 123.123.123.45, opt_name: server-ip-address}
 ],
 
  }
 }
 
 During the development of DHCPv6 function for IPv6 subnets, we found this 
 format doesn't work anymore because an port can have both IPv4 and IPv6 
 address. So we need to find a new way to specify extra_dhcp_opts for DHCPv4 
 and DHCPv6, respectively. ( https://bugs.launchpad.net/neutron/+bug/1356383)
 
 Here are some thoughts about the new format:
 
 Option1: Change the opt_name in extra_dhcp_opts to add a prefix (v4 or v6) so 
 we can distinguish opts for v4 or v6 by parsing the opt_name. For backward 
 compatibility, no prefix means IPv4 dhcp opt. 
 
 extra_dhcp_opts: [
 {opt_value: testfile.1,opt_name: bootfile-name},
 {opt_value: 123.123.123.123, opt_name: v4:tftp-server},
 {opt_value: [2001:0200:feed:7ac0::1], opt_name: 
 v6:dns-server}
 ]
 
 Option2: break extra_dhcp_opts into IPv4 opts and IPv6 opts. For backward 
 compatibility, both old format and new format are acceptable, but old format 
 means IPv4 dhcp opts. 
 
 extra_dhcp_opts: {
  ipv4: [
 {opt_value: testfile.1,opt_name: bootfile-name},
 {opt_value: 123.123.123.123, opt_name: 
 tftp-server},
  ],
  ipv6: [
 {opt_value: [2001:0200:feed:7ac0::1], opt_name: 
 dns-server}
  ]
 }
 
 The pro of Option1 is there is no need to change API structure but only need 
 to add validation and parsing to opt_name. The con of Option1 is that user 
 need to input prefix for every opt_name which can be error prone. The pro of 
 Option2 is that it's clearer than Option1. The con is that we need to check 
 two formats for backward compatibility. 
 
 We discussed this in IPv6 sub-team meeting and we think Option2 is preferred. 
 Can I also get community's feedback on which one is preferred or any other 
 comments?
 

I’m -1 for both options because neither is properly backwards compatible.  
Instead we should add an optional 3rd value to the dictionary: “version”.  The 
version key would be used to make the option only apply to either version 4 or 
6.  If the key is missing or null, then the option would apply to both.

 Right. The special unicorns.
 
  In that case it might
 not make sense to have a life cycle of their own in another repo
 indefinitely.
 
 The main reasons these experimental components don't make sense to live in 
 their own repo indefinitely are:
 
 a) Neutron's design doesn't make it easy or straightforward to build/layer 
 other things on top of it, or:
 

Correct and this something I want the team to address in Kilo.  Many of the L7 
services would be easier to build if we invest some time early in the cycle to 
establishing a well defined interface for a few items.  I’m sure the LBaaS team 
has good feedback to share with everyone.

 b) The experimental piece of code intends to replace whole-hog a large chunk 
 of Neutron's existing codebase, or:
 
 c) The experimental piece of code relies so heavily on inconsistent, 
 unversioned internal interface and plugin calls that it cannot be designed 
 externally due to the fragility of those interfaces

I’m glad Jim reminded us of the pain of merging histories and the availability 
of feature branches.  I think for items where we’re replacing large chunks of 
code feature branches make lots of sense.

 
 Fixing a) is the solution to these problems. An incubator area where 
 experimental components can live will just continue to mask the true 
 problem domain, which is that Neutron's design is cumbersome to build on top 
 of, and its cross-component interfaces need to be versioned, made consistent, 
 and cleaned up to use versioned data structures instead of passing random 
 nested dicts of randomly-prefixed string key/values.
 
 Frankly, we're going through a similar problem in Nova right now. There is a 
 group of folks who believe that separating the nova-scheduler code into the 
 Gantt project will magically make placement decision code and solver 
 components *easier* to work on (because the pace of coding can be increased 
 if there wasn't that pesky nova-core review process). But this is not 
 correct, IMO. Separating out the scheduler into its own project before 
 internal interfaces and data structures are cleaned up and versioned will 
 just lead to greater technical debt and an increase in frustration on the 
 part of Nova developers and scheduler developers alike.

Right hopefully the incubator will allow us to develop components that should 
be independent from the start without incurring too much debt.

We have quite a bit of experience and some good tools around
splitting

generally do a
lot of importing code into projects.  We've done this once, to my
recollection, in a way that preserved history, and that was with the

It wasn't easy; it's major git surgery and would require significant
infra-team involvement any time we wanted to do it.
 
However, reading the proposal, it occurred to me that it's
pretty clear
that we expect these tools to be able to operate outside of the
Neutron
project itself, to even be releasable on their own.  Why not
just stick
with that?  In other words, the goal of this process should be
to create
separate projects with their own development lifecycle that will
continue indefinitely, rather than expecting the code itself to
merge
into the neutron repo.
 
This has advantages in simplifying workflow and making it more
consistent.  Plus it builds on known integration mechanisms like
APIs
and python project versions.
 
But more importantly, it helps scale the neutron project itself.  I
think that a focused neutron core upon which projects like these can
build on in a reliable fashion would be ideal.
 
 
Despite replies to you saying that certain branches of Neutron
development work are special unicorns, I wanted to say I *fully*
support your above statement.

[openstack-dev] [Neutron] Group Based Policy and the way forward

2014-08-04 Thread Mark McClain
All-

tl;dr

* Group Based Policy API is the kind of experimentation we be should attempting.
* Experiments should be able to fail fast.
* The master branch does not fail fast.
* StackForge is the proper home to conduct this experiment.


Why this email?
---
Our community has been discussing and working on Group Based Policy (GBP) for 
many months.  I think the discussion has reached a point where we need to 
openly discuss a few issues before moving forward.  I recognize that this 
discussion could create frustration for those who have invested significant 
time and energy, but the reality is we need ensure we are making decisions that 
benefit all members of our community (users, operators, developers and vendors).

Experimentation

I like that as a community we are exploring alternate APIs.  The process of 
exploring via real user experimentation can produce valuable results.  A good 
experiment should be designed to fail fast to enable further trials via rapid 
iteration.

Merging large changes into the master branch is the exact opposite of failing 
fast.

The master branch deliberately favors small iterative changes over time.  
Releasing a new version of the proposed API every six months limits our ability 
to learn and make adjustments.

In the past, we’ve released LBaaS, FWaaS, and VPNaaS as experimental APIs.  The 
results have been very mixed as operators either shy away from testing/offering 
the API or embrace the API with the expectation that the community will provide 
full API support and migration.  In both cases, the experiment fails because we 
either could not get the data we need or are unable to make significant changes 
without accepting a non-trivial amount of technical debt via migrations or 
draft API support.

Next Steps
--
Previously, the GPB subteam used a Github account to host the development, but 
the workflows and tooling do not align with OpenStack's development model. I’d 
like to see us create a group based policy project in StackForge.  StackForge 
will host the code and enable us to follow the same open review and QA 
processes we use in the main project while we are developing and testing the 
API. The infrastructure there will benefit us as we will have a separate review 
velocity and can frequently publish libraries to PyPI.  From a technical 
perspective, the 13 new entities in GPB [1] do not require any changes to 
internal Neutron data structures.  The docs[2] also suggest that an external 
plugin or service would work to make it easier to speed development.

End State
-
APIs require time to fully bake and right now it is too early to know the final 
outcome.  Using StackForge will allow the team to retain all of its options 
including: merging the code into Neutron, adopting the repository as 
sub-project of the Network Program, leaving the project in StackForge project 
or learning that users want something completely different.  I would expect 
that we'll revisit the status of the repo during the L or M cycles since the 
Kilo development cycle does not leave enough time to experiment and iterate.

This is an interesting discussion since we would create an API inconsistency

Given that this is an extension, I think that adding new values would be ok

Right we’ve never had a deleted state because the record has been removed 
immediately in most implementations even if the backend has not fully cleaned 
up.  I was thinking for the v3 core we should have a DELETING state that is set 
before cleanup is dispatched to the backend driver/worker.  The record can then 
be deleted when the backend has cleaned up.

For unattached objects, I’m -1 on QUEUED because some will interpret that the 
system is planning to execute immediate operations on the resource (causing 
customer queries/complaints about why it has not transitioned).  Maybe use 
something like DEFERRED, UNBOUND, or VALIDATED?

German,

First of all extension list looks lbaas-centric right now.

Actually far from it.  SSL VPN should be service extension.


Secondly, TLS and L7 are such APIs which objects should not require 
loadbalancer or flavor to be created (like pool or healthmonitor that are pure 
db objects).
Only when you associate those objects with loadbalancer (or its child objects), 
driver may tell if it supports them.
Which means that you can't really turn those on or off, it's a generic API.

The driver should not be involved.  We can use the supported extensions to 
determine is associated logical resources are supported.  Otherwise driver 
behaviors will vary wildly.  Also deferring to driver exposes a possible way 
for a tenant to utilize features that may not be supported by the operator 
curated flavor.

From user perspective flavor description (as interim) is sufficient to show 
what is supported by drivers behind the flavor.

Supported extensions are critical component for this.


Also, I think that turning extensions on/off is a bit of side problem to a 
service specification, so let's resolve it separately.

 Hi,

 Mark and me has spent some time today discussing existing proposals
 and I think we got to a consensus.
 Initially I had two concerns about Mark's proposal which are
 - extension list attribute on the flavor
 - driver entry point on the service profile

 The first idea (ext list) need to be clarified more as we get more
 drivers that needs it.
 Right now we have FWaaS/VPNaaS which don't have extensions at all and
 we have LBaaS where all drivers support all extensions.
 So extension list can be postponed until we clarify how exactly we
 want this to be exposed to the user and how we want it to function on
 implementation side.

 Driver entry point which implies dynamic loading per admin's request
 is a important discussion point (at least, previously this idea
 received negative opinions from some cores) We'll implement service
 profiles, but this exact aspect of how driver is specified/loadede
 will be discussed futher.

 So based on that I'm going to start implementing this.
 I think that implementation result will allow us to develop in
 different directions (extension list vs tags, dynamic loading and
 such) depending on more information about how this is utilized by deployers 
 and users.

 Thanks,
 Eugene.

 There are still two proposals [1] [2], and after the meeting last

 a bunch of comments on both proposals.

 I'm going to again suggest we spend some time discussing this at the

 Hi,
 
 Is there any way in current neutron codebase that can be used to validate

 E.g. , in models_v2.py
 
 class Network(model_base.BASEV2, HasId, HasTenant):

 And if I want to validate the 'name' before storing in db, then how can I
 get the max allowable length given this definition?  I don't see any such
 validations being done in neutron for fields, so wondering how to do it.
 Maybe it's there and I missed it.
 


There’s not any length validation currently as the original v2 API spec never 
specified the max field length.  One of the changes being made as part of the 
REST layer refactoring is that we’re adding length validation.

Is anyone using Neutron for high bandwidth workloads? (for sake of discussion 
let’s “high” = “50Gbps or greater”)

With routers being implemented as network namespaces within x86 servers it 
seems like Neutron networks would be pretty bandwidth constrained relative to 
“real” routers.

As we start migrating the physical connections on our physical routers from 
multiple of 10G to multiples of 100G, I’m wondering if Neutron has a clear 
roadmap towards networks where the bandwidth requirements exceed what an x86 
box can do.

Is the thinking that x86 boxes will soon be capable of 100G and multi-100G 
throughput? Or does DVR take care of this by spreading the routing function 
over a large number of compute nodes so that we don’t need to channel 
multi-100G flows through single network nodes?

I’m mostly thinking about WAN connectivity here, video and big data 
applications moving huge amounts of traffic into and out of OpenStack based 
datacenters.


There are few internal implementations of the l3 plugin that are backed by 
dedicated hardware vs commodity+network namespaces.  Of those few, all are site 
specific (due to limited feature support and not likely to upstreamed).

Re: [openstack-dev] [Neutron] Core API refactoring

Hi Sean:

While the APIs might not be changing*, I suspect that there are significant 
design decisions being made**. These changes are probably more significant than 
any new feature being discussed. As a community, are we expected to document 
these design changes and review these changes as well?

There was a bit of high level discussion needed to ensure community consensus 
before we could dive into the details.  The actual changes will be documented 
according to Neutron’s spec process.


I am still trying to figure out what Neutron's review standards are. On one 
hand, I am seeing code review comments that reject a patch for cosmetic changes 
(like a name change from what was in the reviewed blueprint), to having an 
attitude that something as core and central to neutron as refactoring and a 
major API update to v3 not needing a design document/review.

It is my opinion, and my recommendation, that the proposed changes be 
documented and reviewed by same standard that we have for other features.

That has been the plan all along to follow the spec process as with all other 
changes to Neutron.


* I believe that v3 API is being introduced and chnages are being made, but I 
might have mis-understood.

It is important to note that the changes are to the code level interfaces 
within the neutron-server executable and no user facing REST changes.  The 
intent is to keep compatibility with existing V2 plugins while moving towards a 
new V3 plugin architecture.  Our dev cycle is really short, so inserting this 
new layer will be in preparation for a formal V3 definition declared during the 
K cycle.  The discussion intentionally avoided any changes to logical and/or db 
models for this very reason.


** I was under the impression that in addition to the Pecan updates, there was 
going to be refactoring to use taskflow as well. And that I expect to have 
significant control flow impact, and that is what I really wanted to review.

Moving towards tasks is actually independent of the changes to the REST layer.  
Tasks will refactor the implementation of the actual plugins, but should not 
require any cooperation with the REST layer.

The only reason the advance services team would be out in the cold is that

Some of the background reasoning for suggesting this is available at:

I’ve added comment there to provide additional information, but I do not think 
splitting these out are in the best interest of the community because of the

Hope to see you there to discuss how we best make sure that the advanced

On May 2, 2014, at 7:39 AM, Sean Dague s...@dague.net wrote:

 Some non insignificant number of devstack changes related to neutron
 seem to be neutron plugins having to do all kinds of manipulation of
 extra config files. The grenade upgrade issue in neutron was because of
 some placement change on config files. Neutron seems to have *a ton* of
 config files and is extremely sensitive to their locations/naming, which
 also seems like it ends up in flux.

We have grown in the number of configuration files and I do think some of the 
design decisions made several years ago should probably be revisited.  One of 
the drivers of multiple configuration files is the way that Neutron is 
currently packaged [1][2].  We’re packaged significantly different than the 
other projects so the thinking in the early years was that each plugin/service 
since it was packaged separately needed its own config file.  This causes 
problems because often it involves changing the init script invocation if the 
plugin is changed vs only changing the contents of the init script.  I’d like 
to see Neutron changed to be a single package similar to the way Cinder is 
packaged with the default config being ML2.

 
 Is there an overview somewhere to explain this design point?

Sadly no.  It’s a historical convention that needs to be reconsidered.

 
 All the other services have a single config config file designation on
 startup, but neutron services seem to need a bunch of config files
 correct on the cli to function (see this process list from recent
 grenade run - http://paste.openstack.org/show/78430/ note you will have
 to horiz scroll for some of the neutron services).
 
 Mostly it would be good to understand this design point, and if it could
 be evolved back to the OpenStack norm of a single config file for the
 services.
 

+1 to evolving into a more limited set of files.  The trick is how we 
consolidate the agent, server, plugin and/or driver options or maybe we don’t 
consolidate and use config-dir more.  In some cases, the files share a set of 
common options and in other cases there are divergent options [3][4].   Outside 
of testing the agents are not installed on the same system as the server, so we 
need to ensure that the agent configuration files should stand alone.  

To throw something out, what if moved to using config-dir for optional configs 
since it would still support plugin scoped configuration files.  

Neutron Servers/Network Nodes
/etc/neutron.d
neutron.conf  (Common Options)
server.d (all plugin/service config files )
service.d (all service config files)


Hypervisor Agents
/etc/neutron
neutron.conf
agent.d (Individual agent config files)


The invocations would then be static:

neutron-server —config-file /etc/neutron/neutron.conf —config-dir 
/etc/neutron/server.d

Service Agents:
neutron-l3-agent —config-file /etc/neutron/neutron.conf —config-dir 
/etc/neutron/service.d

Hypervisors (assuming the consolidates L2 is finished this cycle):
neutron-l2-agent —config-file /etc/neutron/neutron.conf —config-dir 
/etc/neutron/agent.d

Thoughts?

I'm trying to make sense of the allow_overlapping_ips configuration parameter

When this entry is true, then a tenant can have subnets with overlapping IPs in 
different networks (i.e. the scope of the subnet validation search is the other 
subnets associated with the network) which makes sense.

But, when this entry is false, then the validation search appears to cover all 
subnets across all tenants.  I'm trying to understand the logic of this, 
because I would have expected that in this case, the search scope would be all 
subnets across a single tenant.

As it is now, it looks like if an install has this configuration parameter set 
to false, then there is no way for that install to reuse the net 10 address 
space.

Can somebody lend me a hand and either (a) tell me I'm reading the code wrong 
or (b) explain why that choice was made?

You are reading the code correctly. This feature is largely a legacy option for 
older distros that do not support namespaces or when the deployer chooses to 
run in a flat mode without tenant isolation.

[openstack-dev] TC Candidacy

2014-04-14 Thread Mark McClain
All-

I'd like to announce my candidacy to continue serving on the Technical 
Committee.


Platform
---
OpenStack is one community comprised of many parts and we must view ourselves 
as one unit. As a TC member, I will continue to place the interests of the 
larger community over those of those of individual projects.

There are several key areas I'd like to see the TC focus on:

Development
The Technical Committee should serve as a high level forum to 
facilitate defining cross project technical and procedural requirements. While 
many of our programs share commonalities, there are still differences in 
policies and technical decisions. The TC should continue its work to build 
consensus and reduce the differences between the projects so the community can 
function as one body.  

Cross Project Communication
Cross project communication is essential to maintaining a unified 
stable OpenStack release.  When serving as PTL, I worked to facilitate a 
mid-cycle meetup specifically designed to increase interaction between QA and 
Networking teams.  I believe the TC should promote similar cross-project 
initiatives where deep collaboration enhances the unity of our community.

Process
A recurring theme during the most recent term of the TC has been the 
refinement of our program and project maturation process. The committee needs 
to continue this work as it clarifies and strengthens the criteria used to 
determine the kind of projects and programs that fit within the scope of 
integrated releases and how they move through the progression of incubation to 
graduation.  The growth of our community project ecosystem is very exciting, 
but we’re currently limited in our ability to scale the number of incubated 
projects.  The TC should examine how we can better scale the number of 
incubated projects while ensuring a successful integration into the release 
process.

Unified Experience
For OpenStack to be successful we must strive to provide a unified 
experience for both users and deployers.  Users want tools that are well 
documented and easy to use. The documentation and tools must be portable across 
deployments (both public and private) so that users do not need to concern 
themselves with the implementation details. At the same time, deployers should 
be able to upgrade between releases and maintain a known level of 
compatibility. Our community has invested significant effort to improve this 
experience and this should remain a focus going forward.


About Me
-
I am currently a member of the Technical Committee and a former PTL. Believing 
that OpenStack is a unified community, I have contributed code and reviews to 
nearly all of our integrated projects since my first contribution during the 
Essex cycle. I believe that cross project contributions are essential to foster 
collaboration and sharing of ideas within our community. I'm a member of the 
Stable Release Team and the Requirements Team. My work on both teams provides a 
cross project view of our community with an eye towards stability and 
consistency.  Outside of development, I travel extensively to advocate and 
educate on OpenStack and interact with our community of developers, deployers 
and users.

We have built a very special open community through the contributions of many.  
These contributions have powered our phenomenal growth and I'm excited about 
our future!

Thanks,

[openstack-dev] [Neutron] PTL Candidacy

2014-03-31 Thread Mark McClain
All-

I writing to announce my candidacy for the OpenStack Networking (Neutron) PTL.

I am the current Neutron PTL and would like to continue leading our team during 
the Juno cycle.  As PTL, I have worked to promote a vibrant open ecosystem of 
deployers, integrators and vendors within Neutron.  Our openness is exemplified 
by the new drivers/plugins, new contributors, and diversity of sub team 
leadership in Icehouse.

Qualifications
---
I have been a contributor to Neutron since Essex and a core team member since 
Folsom.  I have been developing software with Python professionally for 14 
years and currently work for Yahoo!, a deployer of OpenStack.  Within the 
Neutron code base, I have worked extensively on DHCP, IP library, network 
namespaces, metadata services, database migrations, and LBaaS reference 
implementation.  I frequently present Neutron at local and regional OpenStack 
events to build community by engaging new developers, deployers, and 
integrators.

I am the top reviewer during the Icehouse cycle:
http://russellbryant.net/openstack-stats/neutron-reviewers-180.txt

I am the top reviewer since the inception of Neutron:
http://russellbryant.net/openstack-stats/neutron-reviewers-1095.txt

Icehouse

As the technical lead during Icehouse, I kicked off the initiative to improve 
testing within Neutron.  This initiative included the creation of the mid-cycle 
sprint that brought the QA and Neutron teams together.  The successful sprint  
produced a more stable Neutron core, more API test coverage, the soon-to-be 
enabled full Tempest and Grenade jobs and a more connected community.  
Additionally, I promoted the policy of improve 3rd party testing of 
plugin/driver code from vendors [1].  This initiative has resulted in a more 
thoroughly tested and stable driver/plugin codebase for operators to deploy.

Juno
---
My vision for Juno is that our team continue to build upon the open environment 
that enables all vendors, deployers and integrators the opportunity to 
contribute to the development of Neutron.  During the cycle, I believe our team 
should focus on a few core initiatives:

* Nova Parity
We committed to delivering Nova Parity when Neutron was accepted as an 
Integrated project.  By delivering Distributed Virtual Routing, Nova-Network to 
Neutron migration, testing and documentation we will be following through on 
our commitment to the greater OpenStack community.

* Advanced Services
The team should implement a multi-vendor ‘flavor' API that provides tenants an 
easy to use API, deployers a choice and vendors an opportunity to innovate.  
This API should complement the existing APIs our teams have created over the 
last two cycles.  Additionally, we should add secure APIs and agent code to 
support SSL termination for LBaaS and SSL VPNs.

* Process Improvements
Our team has grown, but our processes for submitting and reviewing blueprints 
has largely stayed the same which has made the review process uneven. As the 
Icehouse cycle has wound down, I have been working to put new infrastructure in 
place to improve the blueprint process for Juno[2].  The new process should 
ensure a more consistent experience for all contributors in Juno.  In addition 
to refining the blueprint process, our sub team structure should be revised to 
improve communication, remove blockers, and facilitate more efficient reviews.

* Internal API and REST API Improvements
We have several exciting new features in development for Neutron, but at times 
our internal APIs have inhibited efficient implementation of these features.  
During the Juno cycle, we should begin the process of revising our internal 
interfaces to enable easier IPv6, migration to Python 3 and development of 
plugins/drivers and services,

* Group Policy
There is significant community interest in adding policy support to Neutron.  
During Juno, we should work on implementing the first iteration of the policy 
API extension.  This extensions will be aided by the work to improve the 
internal API.

* Testing
The team made significant testing gains during Icehouse.  We should build on 
that work during Juno and collaborate with the QA team to further refine and 
improve our testing through additional scenarios, varied migration 
configurations and functional tests.

* Documentation
Good documentation is a requirement for both deployers and developers we have 
made improvements to both Icehouse.  For Juno, I’d like to continue this work 
as it is essential for parity.

* Growing our plugin and driver community

See something missing from this list?  As PTL, I’m excited to work with our

Hi,

So recently we started this experiment with the compute and qa programs
to try using Gerrit to review blueprints.  Launchpad is deficient in
this area, and while we hope Storyboard will deal with it much better,
but it's not ready yet.

This seems to be a point of confusion.  My view is that Storyboard isn't
intended to implement what gerrit provides.  Given that, it seems like
we'd still be using this whether the tracker is launchpad or storyboard.

I don't think it's intended to implement what Gerrit provides, however,
I'm not sure what Gerrit provides is _exactly_ what's needed here.  I do
agree that Gerrit is a much better tool than launchpad for collaborating
on some kinds of blueprints.


Agreed, but the current blueprint system is broken in a way that a half step 
with an imperfect tool is better than keeping the status quo.

However, one of the reasons we're creating StoryBoard is so that we have
a tool that is compatible with our workflow and meets our requirements.
It's not just about tracking work items, it should be a tool for
creating, evaluating, and progressing changes to projects (stories),
across all stages.

I don't envision the end-state for storyboard to be that we end up
copying data back and forth between it and Gerrit.  Since we're
designing a system from scratch, we might as well design it to do what
we want.

One of our early decisions was to say that UX and code stories have
equally important use cases in StoryBoard.  Collaboration around UX
style blueprints (especially those with graphical mock-ups) sets a
fairly high bar for the kind of interaction we will support.

Gerrit is a great tool for reviewing code and other text media.  But
somehow it is even worse than launchpad for collaborating when visual
media are involved.  Quite a number of blueprints could benefit from
better support for that (not just UI mockups but network diagrams, etc).
We can learn a lot from the experiment of using Gerrit for blueprint
review, and I think it's going to help make StoryBoard a lot better for
all of our use cases.

Diagram handling was one of the first questions I asked Russell when I saw the 
repo creation proposal.  Diagrams are very helpful and while gerrit is not 
ideal for handling diagrams, Sphinx should allow us to incorporate them in 
basic way for now.  I view this as an improvement over the 5 different formats 
blueprints are submitted in now.


I think that's fine if long term this whole thing is optimized. I just
do very much worry that StoryBoard keeps going under progressive scope
creep before we've managed to ship the base case. That's a dangerous
situation to be in, as it means it's evolving without a feedback loop.

I'd much rather see Storyboard get us off launchpad ASAP across all the
projects, and then work on solving the things launchpad doesn't do.


+1000 I don’t want to see Storyboard changing scope to the point where it 
doesn’t adequately deliver because it is trying to solve too many problems in 
the first iteration.

Re: [openstack-dev] [neutron] Globally-unique VM MAC address to do vendor-backed DHCP

Hi stakers,

We’re trying to replace dnsmasq-supplied DHCP for tenant VMs with a vendor’s 
baremetal DHCP server. In order to pass DHCP request to a vendor’s server and 
send DHCP response back to VM we decided to add another OVS bridge (we called 
it br-dhcp), connected to integration bridge (br-int), which will have OVS 
rules connecting VM’s MAC address with br-dhcp port. In this scenario DHCP 
response will only find it’s way back to a VM if VM has globally-unique MAC 
address.

My questions are:

  *   is having code which generates globally-unique MACs for VMs acceptable by 
the community at all?

This question tends to pop up from time to time and there are valid deployment 
and usage scenarios where you would want to assign the same MAC to multiple 
ports.


  *   is there a better solution to the problem (we also tried using dnsmasq as 
a DHCP relay there)?

That answer really depends on a number of factors.
 - Are the IP allocations being handled inside or outside of Neutron?
 - Do you allow different networks to have overlapping IP ranges?
 -

If it is outside of the OpenStack deployment then your code can use flow mods 
with you br-dhcp. If Neutron is managing the allocations or you allow 
overlapping IPs, you probably want to consider implementing a driver for the 
DHCP server.

You are correct that is the goal of the design summit.  While I do think it is

For now we could run the existing 2 with and without config drive enabled.

 undefined.
 


It should be part of the core API and has been planned that way for some time 
(This was agreed on when we first brought this up in Grizzly)  We need to 
ensure that the new mode attribute provides the correct backwards compatible

[openstack-dev] [Neutron] Plugin and Driver Inclusion Requirements

2013-11-14 Thread Mark McClain
tl;dr
-
The Neutron team has experienced tremendous growth in vendor plugins and 
drivers over the last few cycles.  As a result of the growth, the Neutron team 
is implementing new requirements for plugin and driver code for Icehouse cycle 
to ensure continued code quality and stability.

- Each third party plugin/driver shall designate a point of contact for the 
coordinated release cycle.
- To be designated as compatible, a third-party plugin and/or driver code must 
implement external third party integration testing.
- Policy is in effect immediately for new plugin/drivers.
- Existing plugin/drivers have until Icehouse-2 to become compliant.

Introduction
---
Ensuring release quality through proper testing is an important tenant of the 
OpenStack community and Neutron team wants to do our part. We are introducing 
changes below provide more visibility into the quality and stability of vendor 
plugin and driver code.  The policies described here are in effect immediately.

Rationale

Code proposals for third party plugins have always presented a review challenge 
for the Neutron core team.  In the early days, code was often proposed by core 
project contributors and our review process only validated whether the 
requirements were met for community coding style and unit testing.  As Neutron 
has added new resources via extensions, it has become more difficult for 
Neutron reviewers to ensure the proposed code is functional.  Many of the 
plugins and/or drivers require proprietary hardware and/or software to conduct 
such testing.

In addition to testing changes, the Neutron team is revising the requirements 
for the point of contact for third party code.  The changes bring the written 
expectations for contacts in line with current practice.

Point of Contact Requirements
-
Each third party plugin and/or driver shall designate a point of contact for 
each coordinated release cycle.  The contact will serve as a liaison between 
the Neutron core team and the vendor or community supporting the plugin or 
driver.  The contact shall:
- Attend weekly Neutron team IRC meetings
- Be an active reviewer and contributor 
- Be an active participant on openstack-dev mailing list
- Assist the core team with triaging bugs specific to the plugin and/or 
driver
- Ensure OpenStack development deadlines are properly communicated back 
to their company and/or community

NOTE: The this information can be maintained here: 
https://wiki.openstack.org/wiki/Neutron_Plugins_and_Drivers

Testing Requirements
-
To be designated as compatible, a third-party plugin and/or driver code must 
implement external third party testing.  The testing should be Tempest executed 
against a Devstack build with the proposed code changes.  The environment 
managed by the vendor should be configured to incorporate the plugin and/or 
driver solution.  The OpenStack Infrastructure team has provided details on how 
to integrate 3rd party testing at:

http://ci.openstack.org/third_party.html

and Tempest can be found at:

https://github.com/openstack/tempest

The Neutron team expects that the third party testing will provide a +/-1 
verify vote for all changes to a plugin or driver’s code.  In addition, the 
Neutron team expects that the third party test will also vote on all code 
submissions by the jenkins user.  The jenkins user regularly submits 
requirements changes and the Neutron team hopes to catch any possible 
regressions as early as possible.

Existing Plugin and Drivers
-
Plugins and drivers currently in the Neutron project repository will be given a 
grace period until the Icehouse-2 milestone to implement external third party 
testing.  At that time, the Neutron team will release a list of the compatible 
plugins and drivers (i.e. those that meet the testing requirements).  Plugins 
and drivers that do not have external testing will be deprecated at the 
Icehouse release and will be candidates for removal when the J-release cycle 
opens.

 We have seen the BP and review. The problem that we Neutron core are currently

 haven't decided yet if new plugins will require these tests before being

I’ll send out more information later today, but all new Neutron plugin and 
drivers proposed for inclusion in Icehouse will require testing to be in place 
prior to acceptance into the tree.  Without the proper testing infrastructure 
in place there is  no way for the review team to know if the submitted code

[openstack-dev] [Neutron] PTL Candidacy

2013-09-20 Thread Mark McClain

Hi-

I writing to announce my candidacy for the OpenStack Networking (Neutron) PTL.

I am the current Neutron PTL.  Our team continued to grow during the Havana 
cycle and both existing and new contributors worked to deliver double the 
number of blueprints than the previous release.  Our vibrant ecosystem makes me 
excited for the future of Neutron and I would love to continue as the PTL.

Qualifications
---

I am a Neutron core developer with 13 years of commercial Python development 
experience.  During my career, I have developed and deployed network 
applications based on the same underlying libraries used throughout Neutron.  I 
started contributing to Neutron project during the Essex development cycle.  In 
Folsom, I was promoted to core and was the primary developer of the DHCP 
implementation and Neutron's network namespace library.  During Grizzly, I 
worked on the metadata service, database migrations, and LBaaS reference 
implementation.  

Havana Accomplishments


During the Havana cycle, I worked as a developer, core team member, and a 
technical lead.

- Planned and implemented the Quantum to Neutron name change.
- Most active reviewer on the Neutron team 
(http://russellbryant.net/openstack-stats/neutron-reviewers-180.txt)
- Organized the Networking track at the Havana Design Summit.
- Led bug triaging and sub-team assignment.
- Interfaced with vendors new to Neutron and helped in the integration of their 
plugins.
- Assisted members of the community to further their understanding of Neutron 
and improve Python development best practices.
- Promoted Neutron by delivering presentations at conferences and regional meet 
ups worldwide.


Icehouse
-

During the Icehouse development cycle, I'd like to see the team focus on:

- Continuing to grow the community of contributors and code reviewers.
- Improving documentation for both deployers and developers.
- Build upon the services added in Havana to extend and improve load balancing, 
firewalling, and VPN.
- Integrating plugins from vendors new to the community including FWaaS, LBaaS, 
ML2, VPNaaS plugins/drivers.
- More efficient Neutron system testing and gating including full Tempest 
testing.
- Further work to ease deploying at scale.
- Refactoring the API layer to leverage a common WSGI framework as other 
OpenStack projects.
- Improving database resource modeling and extension management.
- Unified network service management framework. 
- Continued support of the Horizon team to assist with Neutron integration.
- Defined migration path from nova-network to Quantum.

I'd love the opportunity to continue as the PTL and work with the Neutron team 
to fill in the gaps during the design summit in Hong Kong.

Thanks,
mark

 I dislike the idea of passing magical numbers around to define

 protocols with their numbers mapped (such as this constants business)
 and
 a well defined way to validate/list said common constants.
 
 I agree that value should be validated appropriately in general.
 A configurable list of allowed protocols looks good to me.
 
 wishes to add support for a protocol outside of the common case, it
 should
 be added to the list in a pluggable manner.
 Ex: common defines the constants 1, 6, 17 to be valid but
 my_cool_plugin
 wants to support 42. It should be my plugin's responsibility to add 42
 to
 the list of valid protocols by appending to the list given a pluggable
 interface to do so. I do not believe plugins should continue to update
 the
 common.constants file with new protocols, but I do believe explicitly
 stating which protocols are valid is better than allowing users to
 possibly submit protocols erroneously.
 
 I think this is just a case a backend plugin defines allowed protocols.
 
 I also see a different case: a cloud provider defines allowed protocols.
 For example VLAN network type of OVS plugin can convey any type of
 packets
 including GRE, STCP and so on if a provider wants to do so.
 We need to allow a provider to configure the list.
 
 Considering the above, what we need to do looks:
 (a) to validate values properly,
 (b) to allow a plugin to define what protocols should be allowed
   (I think we need two types of lists: possible protocols and
 default allowed protocols)
 (c) to allow a cloud provider (deployer) to customize allow protocols.
   (Of course (c) is a subnet of possible protocols in (b))
 
 Does it make sense?
 The above is just a start point of the discussion and some list can be
 omitted.
 
 # Whether (c) is needed or not depends on the default list of (b).
 # If it is wide enough (c) is not needed. The current list of (b) is
 [tcp, udp, icmp]
 # and it looks too small set to me, so it is better to have (c) too.
 
 If the plugins use a system such as this, it is possible that new,
 common,
 protocols can be found to be core. See NETWORK_TYPE constants.
 
 I think the situation is a bit different. What network types are
 allowed is tightly
 coupled with a plugin implementation, and a cloud provider choose a
 plugin
 based on their needs. Thus the mechanism of NETWORK_TYPE constants
 make sense to me too.
 
 tl;dr: magic constants are no good, but values should be validated in a
 pluggable and explicit manner.
 
 As I said above, I agree it is important to validate values properly in
 general.
 
 Thanks,
 Akihiro

 Hi all,
 
 Arvind, thank you for initiate the discussion about the ip protocol in
 security group rules.
 I think the discussion point can be broken down into:
 
 (a) how to specify ip protocol : by name, number, or both
 (b) what ip protocols can be specified: known protocols only, all
 protocols (or some subset of protocols including unknown protocols)
where known protocols is defined as a list in Neutron (a list
 of constants or a configurable list)
 
 --
 (b) is the main topic Arvind and I discussed in the review.
 If only known protocols are allowed, we cannot allow protocols which
 are not listed in the known protocol list.
 For instance, if tcp, udp and icmp are registered as known
 protocols (this is the current neutron implementation),
 a tenant cannot allow stcp or gre.
 
 Pros of known protocols only is the infrastructure provider can
 control which protocols are allowed.
 Cons is that users cannot use ip protocols not listed in a known list
 and a provider needs to maintain a known protocol list.
 Pros and cons of all protocols allowed is vice versa.
 
 If a list of known protocols is configurable, we can cover both cases,
 e.g., an empty list or a list [ANY] means all

I'm -2.  The original bug has morphed into a mini-feature and is not allowable 
under our feature freeze rules.

There are many valid reasons for allowing 41, 47, etc to a guest and we should 
continue to allow 0=proto_num=255 in Havana.  We should also refocus on the 
original bug intent and normalize the data to prevent duplicate rules in the 
common cases (tcp, udp, icmp, icmp, icmpv6).

Any other changes should be open for discussion in Icehouse as we'll need to 
consider the deployment and backwards compatibility issues.  Feel free to 
proposal a session on this for the Hong Kong summit.

I'm not onboard with option 4 either.  At the last summit, we talked about 
making Neutron easier to deploy.  Using a database to sync configuration state 
adds complexity.  Having some values in a configuration and others in the 
database (even cached) is a recipe for a major headache.  For the deployments 
running multiple instances of Neutron, they should be using Chef, Chef, Salt, 
etc for managing their configs anyway.

Using only configuration files (option 1) remains my preference.

Re: [openstack-dev] [neutron] Renaming and code reviews...

2013-07-08 Thread Mark McClain
The core team took care of renaming the files over the weekend, so that reviews 
going forward should behave as normal. (i.e. Adds are truly additions and 
modifications are mods).  I looked at the review you referenced and that was 
file was a proposed addition before the name change.  Git/Gerrit as behaving as 
expected for this change.

As for making staged changes, that will run into problems as module paths will 
be out-of-sync and the change could not pass the gate.  Additionally, that 
would make it hard for changes to be applied or reverted atomically.

 Many people are converting their code, which is out for review, to neutron. 
 One thing I'm seeing is the files which have been moved and renamed, are 
 showing up as new files (not to pick on it, but as an example  
 https://review.openstack.org/#/c/33297/10/neutron/tests/unit/ml2/test_type_gre.py)
  so it is hard to tell if there are other changes going on.
 
 Should submitters ensure that the change set only has renaming changes (and 
 maybe include a note in the patch set saying so), or is there a way that 
 multiple patch sets can be used to make that clear (like one to rename in the 
 text of the file, and a second one to move the file to a new location)?
 
 Just wondering if there is a way to make reviewing easier…

 Mark,
 
 Can you point me to the BP for this feature?
 I want to keep an eye on it.
 
 Thanks,

 There will be a deployment option where you can configure the default IP 
 allocator.  Additionally, the allocator will be configurable at subnet 
 creation time.

 If the no allocation flag is enabled, all ports will have an empty value 
 for IPs.
  It will increase the config parameters in quantum, should we try it?

 There's work under way to make IP allocation pluggable. One of the options 
 will include not having an allocator for a subnet.

 Developers,
 
 So far in Networking (formerly Quantum) IPs are pre-allocated when a new

 _allocate_ips_for_port(self, context, network, port):
 
 If we are using a real DHCP (not the dnsmasq process) that does not accept 
 static IP allocation because it only allocates IPs based on its own 
 algorithm, how can we tell Networking to not allocate an IP at all?
 I don’t think that is possible based on the code but I would like to know 
 if somebody has gone through the same problem and have a workaround 
 solution.
