 The biggest backlog is nova, and there are discussions of both splitting
 parts out to make nova smaller, as well as adopting feature branches and
 merge windows.  The feature branches could have more reviewers that are
 experts in that area, but not necessarily nova-core.  Hopefully these
 things will help in the Folsom cycle.

I suspect the backlog in linked to the design summit and people taking
time off the week after. It should be gradually absorbed in the
following days.

The long-term solution is indeed smaller groups of topic-experts
reviewers being responsible for a smaller batch of reviews. In the short
term, we might review nova-core membership to make sure it still matches
people who can actually regularly commit time to the review duty.

Sounds like a good way to avoid nasty regressions. And maybe run that

  Hi everyone,
 
  I'm running with Essex 2012.1,
  and have some questions about the nova network operation,
 
  1. Is it possible manually assigned IP address to a launched instance,
 my situation is :
  after instance boot up (OS: CentOS 6.2), I changed the
 /etc/sysconfig/network-scripts/ifcfg-eth0 setting
  from dhcp to static (the same subnet as created by command : nova-manage
 create network), and restart the network service,
  And then I couldn't ssh or ping the instance from other server with the
 same subnet.
  What is the problem ?  I checked the iptables policies on the compute
 host, and find nothing about the DROP packets.
  I also tried to changed the record from nova.fixed_ips table and
 libvirt.xml of the instance, then reboot the instance, still not worked.
  I used FlatDHCP  as my network manager.

 You can't do this.  Libvirt sets up no mac spoofing and no ip spoofing so
 the ip address needs to match the dhcp'd one. You should be able to switch
 to a static and use the same info that you get from dhcp though.
 
  2. According to the first question, I have another requirement to set up
 a loopback IP address (lo:0) on the running instance, after setting was
 completed,I couldn't ping or ssh the loopback IP from the same subnet, and
 I tried to set a alias IP address with eth0:0, but still not get worked.
  Any ideas with this ?


 Not sure

I guess it's the same issue as with setting a different IP from what
dnsmasq provided. You can try ebtables -F; ebtables -t nat -F to flush
those anti spoofing rules.


 
  3. Is there any way to use 2 NICs with different subnets on instances? I
 want to separate the network traffic.
  Now I'm running with one bridged interface (br100), and it works well.
  In order to backup the large log files,
  I'm planing to use 2 NICs for the compute hosts, I want use 2 vNICs on
 instance, one for web service and the other for log backup,
  I think I should create a new network for the second bridged interface,
 but I can't find any document to guild me.

 This is definitely possible with FlatManager (You could use cloud_config
 drive and some version of contrib/openstack-config converted to work with
 centos to set up the interfaces)

 It was possible at one point with FlatDHCPManager as well by creating
 multiple networks and using a specific combination of config options like
 use_single_default_gateway. I don' t know if anyone has tried this for a
 while so there may be issues with it. You might try creating a second
 network and setting use_single_default_gateway and see what happens.

Confirm that it works with Essex release.
If you don't specify  use_single_default_gateway=true your default route
will be jumping from one interface to another. If you both subnets are
covered by --fixed_network, it's fine even without setting
the use_single_default_gateway.


 There are plans underway to support this by only dhcping the first
 interface and allowing a guest agent to set up the other interfaces, but it
 isn't in place yet.

Re: [Openstack] [OpenStack][Nova] Minimum required code coverage per file

2012-04-27 Thread Eoghan Glynn



- Original Message -
  Kevin,  should we start copying openstack-common tests to client
  projects?  Or just make sure to not count openstack-common code in
  the
  code coverage numbers for client projects?
 
 That's a tough one.  If we copy in the tests, they end up being somewhat
 redundant, but slow down the project unit tests, but on the other hand,
 we'd be able to easily demonstrate that that code works properly.  I
 think I'd prefer if we just try to not count openstack-common code
 for code coverage numbers…

Yep, one approach would be for the copy script to decorate the common code
with whatever signals the coverage exclusion (e.g. #pragma: no cover) so
that the code is counted in the openstack-common coverage metrics, but not
counted after being copied into nova/glance/wherever.

Cheers,
Eoghan

2012-04-27 Thread Eoghan Glynn



 https://review.openstack.org/#/c/6847/

Nice!

  * Migrations added during Folsom release cycle could be compacted
  during E release cycle. TBD if/when we do the next compaction.

An alternative idea would be to do the compaction *prior* to the
Folsom relase instead of after, so that the cleanest possible
migration path is presented to non-trunk-chasing users. It could for
example be a task that's part of spinning up the first Folsom-RC.

Its unlikely that after new migrations are added after the release
candidate goes out the door (as these are generally associated with
non-trivial new features, which would have missed the boat at that
late stage). But if there are any, these would have to be adde to
the squashed aggregate migration from the get-go.

Eoghan

[Openstack] Mailing-list split

Hello everyone,

TL;DR summary:
Due to traffic exploding, we will split the current openstack list into
user / usage topics (openstack list) and development / next-version
topics (openstack-dev list).

Long version:

At the Communication session at the design summit [1] we looked at the
state of our communication media in general, and mailing-list in
particular [2].

[1]
http://folsomdesignsummit2012.sched.org/event/366accca0fda271fc23e82b9cb5162cc
[2] http://etherpad.openstack.org/FolsomCommunication

The traffic on the openstack@lists.launchpad.net list doubled in the
last 4 months [3], with more users and deployers asking for information
on OpenStack projects. It becomes difficult for contributors to properly
prioritize their ML reading, and we can no longer have all the
discussions in the same place.

[3] http://openstack.markmail.org/

The proposal is to split between:

1/ Usage, deployment, Essex / current-stable discussions
2/ Development, contribution, Folsom / forward-looking discussions

A new list will be created for (2) and existing contributors will be
asked to subscribe to that new list.

Since we expect to have a more disciplined/focused group in that new
list, we'll define a set of subject prefixes that should be used for
easier client-side/at-a-glance filtering of discussions:

[General] Affects all projects
[Swift] [Nova] [Glance] [Quantum] [Horizon] [Keystone] Project-specific
[Common] openstack-common
[QA] [CI] [Docs] Discussions / Information on specific topics
[...] Add your own here

To keep that list usable, I suggest we aggressively enforce those topics
and redirect inappropriate discussions to the other list when necessary.

To avoid Launchpad list slowness, we would run the new openstack-dev
list off lists.openstack.org. Given the potential hassle of dealing with
spam and delivery issues on mission-critical MLs, we are looking into
the possibility of outsourcing the maintenance of lists.openstack.org to
a group with established expertise running mailman instances. Please let
us know ASAP if you could offer such services. We are not married to
mailman either -- if an alternative service offers good performance and
better integration (like OpenID-based subscription to integrate with our
SSO), we would definitely consider it.

There was a suggestion during the session of using umbrella/siblings
lists to aggregate content from multiple project-specific sublists. I
reviewed the options and I think it introduces a lot of complexity,
reduces flexibility in adding new topics, so client-side filtering
sounds like a better bet. If most people use subject prefixes
appropriately, keeping it simple is probably the best bet.

We'll let you know when the new list is set up.

Regards,

Thanks Vish  Mike.

It works very well after flush the anti-spoofing rules , I  change the IP
address and bind alias IP to an interface,
but when I restart nova-network and nova-compute , I can't ping neither the
IP I changed nor the instances I haven't changed.
I'll try to figure out what happened with that !!

Even I change the IP address, I can't not see the correct address on
Dashboard, because the record of nova.fixed_ips not changed.
I should try with FlatManager to allocate static IP.

Re: [Openstack] Using Nova APIs from Javascript: possible?

2012-04-27 Thread Adrian Smith

I'd be really interested to hear how you go on with the CORS middleware Javier.
Did it work as-is or did you have to modify it? Was there much effort
involved in using it with Nova?

From your experience it sounds like there's decent CORS support in browsers
now so it's probably time to submit this change to gerrit.

 Hi all,

 I'm glad to hear that there's a lot of interest in the implementation
 of Openstack JavaScript clients. Actually, in my group we're
 developing a single page application developed entirely in
 JavaScript, that widely supports Nova and Keystone APIs.  This work is
 part of a European Project called FI-Ware (http://www.fi-ware.eu/), in
 which we are currently using Openstack APIs.

 We've modified Nova and Keystone installations by adding CORS support.
 We did it by implementing a kind of filter on their APIs. For doing
 this we used Adam's implementation
 (https://github.com/adrian/swift/tree/cors), and we adapted it to Nova
 and Keystone components. We also developed a JS library
 (http://ging.github.com/jstack/) that can be used by both web and
 Node.js applications, for example. This library aims to provide same
 functionalities as python-novaclient, adding support for Keystone API.

 And finally we are copying Openstack horizon functionality, using JS
 library and other frameworks such as jQuery and Backbone.js to
 implement the web application. This web application is an
 early-stage work, but we will probably publish it by the end of this
 week. I will let you know the github link.

 We didn't find much problems with CORS implementation and support in
 browsers.  For the time being, according to our experiments, the only
 web browser that is not usable at all with this technology is Internet
 Explorer, but we have tried it in Google Chrome, Safari and Firefox as
 well and we didn't have any problems.

 Cheers,
 Javier Cerviño.

  Let me try to summarize:
 
  1.  If you are running from a web browser,  post requests to hosts or
  ports other than the origin are allowed,  but the headers cannot be
  modified.  This prevents the addition of the token from Keystone to
 provide
  single sign on.
 
  2.  There are various browser side technologies (JSONP, CORS) that get
  around this limitation, but they are typically not enabled,  and can be
  considered security issues.  While implementing these might require
 support
  from teh Openstack server,  they are fundamentally browser decisions.
 
 
  This is inaccurate. JSONP is supported by all browsers since ~Netscape
 4.0.
 
  CORS is supported by all modern browsers: IE  8, Firefox  3.5, Chrome
  3,
  Safari  4
  (See
 http://en.wikipedia.org/wiki/Cross-origin_resource_sharing#Browser_support
 ).
  Additionally, CORS support is not a browser decision - the server has to
  EXPLICITLY opt-in to support it.
 
  Obviously CORS support *can* be a security issue - that is why it is
  disabled unless the server enables it.
 
  I do not believe that CORS support adds any additional security issues
 above
  what the OpenStack APIs already face. Specially, the most common problem
  (CSRF) is not an issue here because the APIs are not authorised on a
 session
  basis.
 
   [snip]
 
 
  I've been working on Single Sign on Issues for another project for the
  past year and a half.  Here's a couple things I've learned.
 
 
  Kerberos is designed to solve this problem.  It has the benefit of
 being
  integrated into the browser.  Where Kerberos fails is that:  typically
 it
  only allows a single authentication provider (KDC in Kerberso speak)
 and it
  does not work well with Firewalls.
 
  The only crytographically secure way to authenticate on the web that
 can
  get around the firewall issue is Client side X509 certificates.  This

Re: [Openstack] questions about IP addressing and network config

2012-04-27 Thread Mike Scherbakov

Jimmy,
Nova is designed to manage IP addresses.
That means that even with Flat manager it will be allocating IP addresses
for you,
storing them in DB. The difference btw FlatDHCP is Flat injects
/etc/network/interfaces to the instance,
not providing IP by DHCP. So, anti-spoofing rules should be the same (I
never checked though for Flat).

If you want to provide your own addresses to instances, I believe you will
need to extend nova code
to provide your custom IP address in API request, and then if it's not
already allocated, it should get allocated.

Regards,

 Thanks Vish  Mike.

 It works very well after flush the anti-spoofing rules , I  change the IP
 address and bind alias IP to an interface,
 but when I restart nova-network and nova-compute , I can't ping neither
 the IP I changed nor the instances I haven't changed.
 I'll try to figure out what happened with that !!

 Even I change the IP address, I can't not see the correct address on
 Dashboard, because the record of nova.fixed_ips not changed.
 I should try with FlatManager to allocate static IP.

  Hi everyone,
 
  I'm running with Essex 2012.1,
  and have some questions about the nova network operation,
 
  1. Is it possible manually assigned IP address to a launched instance,
 my situation is :
  after instance boot up (OS: CentOS 6.2), I changed the
 /etc/sysconfig/network-scripts/ifcfg-eth0 setting
  from dhcp to static (the same subnet as created by command :
 nova-manage create network), and restart the network service,
  And then I couldn't ssh or ping the instance from other server with
 the same subnet.
  What is the problem ?  I checked the iptables policies on the compute
 host, and find nothing about the DROP packets.
  I also tried to changed the record from nova.fixed_ips table and
 libvirt.xml of the instance, then reboot the instance, still not worked.
  I used FlatDHCP  as my network manager.

 You can't do this.  Libvirt sets up no mac spoofing and no ip spoofing
 so the ip address needs to match the dhcp'd one. You should be able to
 switch to a static and use the same info that you get from dhcp though.
 
  2. According to the first question, I have another requirement to set
 up a loopback IP address (lo:0) on the running instance, after setting was
 completed,I couldn't ping or ssh the loopback IP from the same subnet, and
 I tried to set a alias IP address with eth0:0, but still not get worked.
  Any ideas with this ?


 Not sure

 I guess it's the same issue as with setting a different IP from what
 dnsmasq provided. You can try ebtables -F; ebtables -t nat -F to flush
 those anti spoofing rules.


 
  3. Is there any way to use 2 NICs with different subnets on instances?
 I want to separate the network traffic.
  Now I'm running with one bridged interface (br100), and it works well.
  In order to backup the large log files,
  I'm planing to use 2 NICs for the compute hosts, I want use 2 vNICs on
 instance, one for web service and the other for log backup,
  I think I should create a new network for the second bridged
 interface, but I can't find any document to guild me.

 This is definitely possible with FlatManager (You could use cloud_config
 drive and some version of contrib/openstack-config converted to work with
 centos to set up the interfaces)

 It was possible at one point with FlatDHCPManager as well by creating
 multiple networks and using a specific combination of config options like
 use_single_default_gateway. I don' t know if anyone has tried this for a
 while so there may be issues with it. You might try creating a second
 network and setting use_single_default_gateway and see what happens.

 Confirm that it works with Essex release.
 If you don't specify  use_single_default_gateway=true your default route
 will be jumping from one interface to another. If you both subnets are
 covered by --fixed_network, it's fine even without setting
 the use_single_default_gateway.


 There are plans underway to support this by only dhcping the first
 interface and allowing a guest agent to set up the other interfaces, but it
 isn't in place yet.

[Openstack] Swift authentication using keystone (Essex deploy manual)

2012-04-27 Thread Lucio Cossio

Hey there

I'm installing my OpenStack Essex environment with ubuntu 12.04 using the
new deploy manual from docs.openstack.org and i'm having problems to make
swift work with keystone.

I had everything installed but swift, because as far as I remember the
manual didn't had a swift insllation and setup section, but now it does so
I'm using it.

I installed everything in a single node (192.168.100.140) using the manual,
and now I'm installing swift in another single node (192.168.100.138) using
an old swift manual for a all-in-one installation without keystone. After I
made swift work without keystone, I setup the endpoint for my swift node,
and used the proxy-server.conf file from the new manual.

Here's the output when I get my token from keystone
http://paste.openstack.org/show/13988/ and then I try to use it to list
swift containers but it gives me a 503 http error
http://paste.openstack.org/show/13989/
my proxy-server.conf file http://paste.openstack.org/show/13991/

Can someone help me to configure that

Re: [Openstack] Using Nova APIs from Javascript: possible?

2012-04-27 Thread javier cerviño

Hi!

We have just published the code of the portal in Github. You can find it in
https://github.com/ging/horizon-js. It will only work with Keystone and
Nova if they have CORS implemented.

Adrian, we didn't make big changes in your code, only logger classes and a
little problem we found with PUT requests in some cases (I have to take a
deeper look into this problem, anyway). We've made tests from  iPhone,
iPad, Safari, Firefox and Chrome and we didn't have any problems. But on
the other hand CORS doesn't work in IE9 with PUT and DELETE methods. Next
week I will test it with Android and Opera browsers.

Sure! It will be very interesting to submit your code to gerrit!!

Diego, I will talk with Joaquin to check if we can show you a demo in two
weeks!!

Cheers,
Javier.

2012/4/27 Adrian Smith adrian_f_sm...@dell.com

 I'd be really interested to hear how you go on with the CORS middleware 
 Javier.
 Did it work as-is or did you have to modify it? Was there much effort
 involved in using it with Nova?

 From your experience it sounds like there's decent CORS support in
 browsers now so it's probably time to submit this change to gerrit.

 Hi all,

 I'm glad to hear that there's a lot of interest in the implementation
 of Openstack JavaScript clients. Actually, in my group we're
 developing a single page application developed entirely in
 JavaScript, that widely supports Nova and Keystone APIs.  This work is
 part of a European Project called FI-Ware (http://www.fi-ware.eu/), in
 which we are currently using Openstack APIs.

 We've modified Nova and Keystone installations by adding CORS support.
 We did it by implementing a kind of filter on their APIs. For doing
 this we used Adam's implementation
 (https://github.com/adrian/swift/tree/cors), and we adapted it to Nova
 and Keystone components. We also developed a JS library
 (http://ging.github.com/jstack/) that can be used by both web and
 Node.js applications, for example. This library aims to provide same
 functionalities as python-novaclient, adding support for Keystone API.

 And finally we are copying Openstack horizon functionality, using JS
 library and other frameworks such as jQuery and Backbone.js to
 implement the web application. This web application is an
 early-stage work, but we will probably publish it by the end of this
 week. I will let you know the github link.

 We didn't find much problems with CORS implementation and support in
 browsers.  For the time being, according to our experiments, the only
 web browser that is not usable at all with this technology is Internet
 Explorer, but we have tried it in Google Chrome, Safari and Firefox as
 well and we didn't have any problems.

 Cheers,
 Javier Cerviño.

Count me in, Monty.

I've been managing mailman lists for about 12 years now (and,
incidentally, Barry and I are bruthas from anutha mutha), so I'd be
quite comfortable handling those responsibilities. I can couple it
with the python.org SIG mail list that I manage, so there'd be zero

 Nice!

   * Migrations added during Folsom release cycle could be compacted
   during E release cycle. TBD if/when we do the next compaction.

 An alternative idea would be to do the compaction *prior* to the
 Folsom relase instead of after, so that the cleanest possible
 migration path is presented to non-trunk-chasing users. It could for
 example be a task that's part of spinning up the first Folsom-RC.

 Its unlikely that after new migrations are added after the release
 candidate goes out the door (as these are generally associated with
 non-trivial new features, which would have missed the boat at that
 late stage). But if there are any, these would have to be adde to
 the squashed aggregate migration from the get-go.

I thought about this... but that still leaves only a couple weeks to catch any 
issues that might come up in the release candidate phase. Also, using the RC 
makes the compaction point a bit more fuzzy for end users who are following 
trunk more closely. I do like that it would keep the release tree cleaner 
however.

Performing the compaction after release is sort of a middle ground approach 
which should allow us to clean house from time to time but also keep things 
stable around release time.

 Eoghan

What are general thoughts on this approach?


Is there any support in sqlalchemy, or related tools, to handle 
migrations the way rails does, where a schema file is created at the end 
of every migration? It would be ideal if we both had a full migration

Re: [Openstack] Public image repository via a synchronization script

2012-04-27 Thread Scott Moser

On Wed, 25 Apr 2012, Justin Santa Barbara wrote:

 I think it would be very convenient to have public image repositories and
 an easy way to use them, so someone installing OpenStack can easily get
 images into Glance with minimal work.

 At the design summit, there were a number of talks which all seemed to
 hinge on how to get an image into glance from a public store.  I'd like to
 make a proposal to get the ball rolling, which we can collectively pick
 apart to figure out the best way.

1. A public image repository lives on an HTTP / FTP / ... site and can
be dumb. (Glance could one day be the server here as well, but this should
also work on a CDN or simple webserver etc).
2. Each image is stored as a (possibly compressed) file.

fwiw, qcow images support compression inside:
  qemu-img convert -c disk.img -O qcow2 my.qcow2

compression is potentially useful elsewhere.  It might be good thoguh, in
your properties to explicitly list this rather than implying by the name.

3. Each image has a .properties file alongside it.
4. There is a 'directory' file which lists the property files.  An
md5sum of the directory is easy, and the hashes be useful generally.
5. If there are different sets of images, we have multiple directory
files.  They can point to the same images.
6. We don't try to solve security initially.  But this could be as
simple as signing the directory files, if they had hashes of all the other
files (e.g. md5sum).

Overall, I think this looks reasonable.  A couple nits:
 * I don't like using md5sum as a directory file.  Better to explicitly
   name something for that purpose.  There could be other files in that
   directory that are not images (and would be desireable to appear in the
   md5sum file)
 * your example .properties file contains things that aren't really
   properties (where properties == things that would be added to glance as
   tags)
 disk_format=qcow2
 container_format=bare
 is_public=True
   * Disk format, container_format are useful, but its possibly confusing
 as its an attribute of the image, while other things are tags.
   * is_public=True
 Just because you thought this image should be public does not mean I
 do when I sync it.

I  might suggest, something like this (hand-yaml formated):
  tags:
org.openstack__1__os_distro=debian.org
org.openstack__1__os_version=6.0.4
org.openstack__1__architecture=x64
org.openstack__1__updated_at=20120425
  data:
file: debian_squeeze_20120425.qcow2.gz
disk_format: qcow2
container_format: bare
md5sum: 224237ee1b9a341ac7d79bcebda0580d
size: 627965952
compression: gzip

Alternatively, 'data' above could be named 'org.openstack.sync__1__image'
or something.

Ben Howard has been doing something similar to this with
  https://code.launchpad.net/~utlemming/+junk/sync-images
which reads data at
  https://cloud-images.ubuntu.com/query2/

I'd like to work together to get something that addresses both sets of
needs.

Also, if we do this well, I suppose that the glance aggregator described
at https://blueprints.launchpad.net/glance/+spec/public-glance
http://etherpad.openstack.org/FolsomGlanceReadOnlyGlance could potentially
support this source something it presented in its aggregated list.

[Openstack] proposal for Russell Bryant to be added to Nova Core

Russell Bryant wrote the Nova Qpid rpc implementation and is a member of the 
Nova security team. He has been helping chipping away at reviews and 
contributing to discussions for some time now.

I'd like to seem him Nova core so he can help out w/ reviews... definitely the 
RPC ones.

  Hi All,


Hi Salman,



 I am trying to learn the functionality of Quantum plugins used in
 OpenStack. I have read through the Quantum Admin Guide and had few
 basic/quick question about quantum and OVS interaction with it:


 1) OVS can have ports in which vNICS can be plugged, so why does it need
 to use an integration bridge for connecting all VMs on the same node to a
 network?


I'm not sure I follow what question you're asking.  When OVS is running on
a host, it has one or more bridges, and bridges have ports.  A linux
device representing the vNIC must be added as a port of a bridge being
managed by the Quantum plugin.  We call this bridge the integration
bridge.   The Quantum plugin can then configure the ports and bridges
appropriately to forward traffic based on the logical model created via the
Quantum API.  Can you be more precise about what you're asking here?




 2) The OVS quantum plugin seems to implement the core API functions and
 (viewing the code) I concluded that it just makes maintains the logical
 mappings e.g. b/w net IDs and VLAN IDs in a database. So how is this
 mapping implemented on the actual ports of OVS? Is it the OVS quantum agent
 responsible for directing the packets to correct input/output ports based
 on the updates that it gets from the database?


In VLAN-mode, its even simpler than that.  The agent simply puts each port
as a VLAN access port for the right VLAN, based on the database, and then
has OVS perform standard L2 learning to forward packets.



 3) The quantum admin guide says that the nova client will be the main user
 of quantum and will interact with it via REST API, so it would be nice if
 someone can point me to the code (file path name etc.) where this happens.


This is the QuantumManager code in Nova:
https://github.com/openstack/nova/tree/master/nova/network/quantum

One word of warning: this code will be being simplified and largely removed
in Folsom, so while its useful to look at it to learn about Quantum, I'd
ask around before investing the time to make significant changes to the
code.



 PS: What is the purpose of Quantum Manager in this architecture and where
 should I look for its code?


see above :)

 Just to be clear - I definitely think that mailing lists are an

 someone out there had time or resources and wanted to join us on the
 infra team to manage this on our existing resources (turns out we have
 plenty of servers for running this, and even a decent amount of

 happy to be involved, and it would help avoid get-hit-by-a-truck issues.
 We're a pretty friendly bunch, I promise.

 Any takers? Anybody want to pony up somebody with some bandwidth to

 Count me in, Monty.
 
 I've been managing mailman lists for about 12 years now (and,
 incidentally, Barry and I are bruthas from anutha mutha), so I'd be
 quite comfortable handling those responsibilities. I can couple it
 with the python.org SIG mail list that I manage, so there'd be zero
 context switching.

You make me very happy! Let's work out the details and stuff...

Check it out - it's like we're, you know, a collaborative community or

Hi again,

After inverstigation, it finally works.

I have the network on my instances in using Quantum.

The fact was I've follow official OVS documentation, and you should not
follow this direction :

ovs-vsctl add-port br-int eth1

Hi Emilien,

Which mode are you running OVS in? VLAN or tunneled? If you are using
VLAN-mode (default) you need to add some physical interface to br-int, so
that VLANs are trunked to the physical network. Is it possible that eth1
was also the interface you were using for IP communication on the box?
That definitely won't work with OVS or the linux bridge. I'll improve the
docs around that to make this more clear.

If you see on the logs file of OVS, you can see that the bridge will not
work properly... that's why my instances did not get the network.

Can you ping me with the error messages (can be offlist)? I still don't
understand what you misconfigured, or how you fixed it.

I've tried ovs-vsctl del-port br-int eth1, restart all the services and
now, all is working.

I have now a dual-node with : Nova-*, Glance, Quantum (without
authentification), Keystone, and Horizon (without Quantum UI yet).

Great to hear. As I mentioned in a previous post, Horizon + Quantum isn't
complete. You won't be able to create networks using Horizon, or boot VMs
while specifying a particular set of vNICs. If you're interested in
helping this work move forward more quickly, I'm happy to put you in touch
with the right people.

Dan

Next steps : QoS, UI, Isolation testing, and documentation :-)

I will continue to post about Quantum when I will advance in the project.

That is correct. In the Quantum Admin Guide, it explains some work that
was done to support Keystone Authn, but notes that this is all
experimental, as the Quantum API does not support Authz. This is because
the only person that calls Quantum in Essex is Nova itself. Troy Toman's
team is working on Quantum Authz for Folsom, so the API can be exposed
directly to tenants.

*- What is working at this time :*

- Quantum-Server with MySQL
- Quantum-Agent (with OVS) on each nova-compute node
- OVS bridge with eth1
- nova-network seems working with Quantum

*- What is not working (yet !) :*

- When I create an instance (from dashboard or with Nova CLI), the
network is created with Quantum, an private IP is attributed to the
instance, but when I check the instance log file, the network interface
doesn't get an IP adress. Here the log :
http://paste.openstack.org/show/13821

Are you able to access the VM via VNC? If you statically configure the

- Horizon with Quantum : I can't integrate Quantum in the dashboard

http://docs.openstack.org/trunk/openstack-compute/admin/content/build-and-configure-openstack-dashboard.html

Essex Horizon does not support Quantum. Its actually not just a Horizon
thing, it has to do with how the Nova + Quantum integration works. Each
Quantum network has to be associated with appropriate IPAM subnet, meaning
the existing . For now, you need to create networks using nova-manage. If
you want VMs to get the default set of NICs, you can then boot them with
Horizon. If you want to specify what networks vNICs are plugged into, this
is only supported via the nova boot command with the --nic option. I'll
flush this out in more detail in the Quantum Admin Guide.

Re: [Openstack] Question on notifications

2012-04-27 Thread Monsyne Dragon

Yes, the publisher_id is servicename.host, so ya, you can determine the compute 
host from that.

Hi all,

I was looking at the notification outputs, which are very useful and I was 
wondering if the way to say figure out which hypervisor a VM is being built on.

There seems to be the following key: publisher_id: compute.buildingbuild 
(event is compute.instance.create.end)

It would seem the stuff after “compute” is the hostname, would that be correct, 
or should the scheduler messages be intercepted, which as example has the 
following:

weighted_host: {
host: buildingbuild,
weight: -1488.0
}

I would think the first practice would be right, since its from the compute 
node instead of the scheduler, but would like some feedback :-)

  I think this scheme would support users who follow stable releases
  as well as users who follow trunk very closely.

  We talked about this at the conference but I thought this issue
  might be near and dear to some of our end users so it was worth
  discussing on the list.

  What are general thoughts on this approach?

 Is there any support in sqlalchemy, or related tools, to handle
 migrations the way rails does, where a schema file is created at the
 end
 of every migration? It would be ideal if we both had a full migration
 history, as well as a short cut at any snap shot to get to the end.

Ah. Yes, the Rails schema.rb. I looked around for just this sort of thing and 
didn't find much. Python-migrate has some experimental support for generating 
models and I did make use of that initially. See 'create_model' below:

[root@nova1 migrate_repo]# python ./manage.py --repository=./ 
--url=mysql://nova:password@localhost/nova
Usage: manage.py COMMAND ...

Available commands:
compare_model_to_db  - compare MetaData against the current 
database state
create   - create an empty repository at the 
specified path
create_model - dump the current database as a Python 
model to stdout
db_version   - show the current version of the 
repository under version control
downgrade- downgrade a database to an earlier 
version
drop_version_control - removes version control from a database
help - displays help on a given command
make_update_script_for_model - create a script changing the old 
MetaData to the new (current) MetaData
manage   - creates a Python script that runs 
Migrate with a set of default values
script   - create an empty change Python script
script_sql   - create empty change SQL scripts for 
given database
source   - display the Python code for a particular 
version in this repository
test - performs the upgrade and downgrade 
command on the given database
update_db_from_model - modify the database to match the 
structure of the current MetaData
upgrade  - upgrade a database to a later version
version  - display the latest version available in 
a repository
version_control  - mark a database as under this 
repository's version control

python-migrate's 'create_model' does not however give you something that 
exactly matches the schema you'd get by running the all the migrations. So auto 
generation doesn't appear to be an option right now. It would be nice to 
contribute python-migrate in this regard and get better support for model 
generation, etc. Maybe a good long term goal?

 By merging migrations, we lose history in git for why the migrations
 were added in the first place.

I'm not sure I understand? Git still has the source code for the old 
migrations. All you'd need to do is checkout an old version of master or look 
at the stable/essex, stable/diablo branches right?

  Mirations don't appear to be particularly slow right now, and it

  What exactly is the benefit of doing this?
 
 Speed wasn't the primary motivation here I suppose. Do we really want
 to continue to maintain 100+ migrations in our codebase over the
 lifetime of the project? As we add more and more to our pep8/hacking
 tools this could become an annoying burden right?

Has that been a problem?

I'm not sure I see where pep8/hacking changes would require changes to
the unmerged migrations but the merged migrations wouldn't require them.
Wouldn't that affect either?

Looking at the logs for the migrations most of the changes (outside of
PEP8 changes) appear to be sqlalchemy related changes, which will exist
regardless if they are merged or not as well.

 I mean why require end users to run migrations that add and drop the
 same table repeatedly?

It's hard to just grep for which migrations drop a table/column added in
a previous migration. Did you see how many are like that when you merged
all of the migrations together?

 I'm not sure I understand? Git still has the source code for the old
 migrations. All you'd need to do is checkout an old version of master
 or look at the stable/essex, stable/diablo branches right?

True, you would just need to go out of your way to look at the history
instead.

I guess it's a matter of pros vs cons. Right now, I'd prefer to not
merge them simply because I haven't seen what the benefit is.

Even better, what would it take to try using Alembic? 
(http://alembic.readthedocs.org/en/latest/front.html#project-homepage)

It's a big improvement over sqlalchemy.  Amongst other things, migrations are 
not numbered, they are linked by dependancy, and run in topological-sort order. 
That there eliminates alot of my migration number got taken... again...

 What are general thoughts on this approach?
 
 Is there any support in sqlalchemy, or related tools, to handle
 migrations the way rails does, where a schema file is created at the
 end
 of every migration? It would be ideal if we both had a full migration
 history, as well as a short cut at any snap shot to get to the end.
 
 Ah. Yes, the Rails schema.rb. I looked around for just this sort of thing and 
 didn't find much. Python-migrate has some experimental support for 
 generating models and I did make use of that initially. See 'create_model' 
 below:
 
 
 [root@nova1 migrate_repo]# python ./manage.py --repository=./ 
 --url=mysql://nova:password@localhost/nova
 Usage: manage.py COMMAND ...
 
Available commands:
compare_model_to_db  - compare MetaData against the current 
 database state
   create   - create an empty repository at the 
 specified path
   create_model - dump the current database as a Python 
 model to stdout
   db_version   - show the current version of the 
 repository under version control
   downgrade- downgrade a database to an earlier 
 version
   drop_version_control - removes version control from a database
   help - displays help on a given command
   make_update_script_for_model - create a script changing the old 
 MetaData to the new (current) MetaData
   manage   - creates a Python script that runs 
 Migrate with a set of default values
   script   - create an empty change Python script
   script_sql   - create empty change SQL scripts for 
 given database
   source   - display the Python code for a particular 
 version in this repository
   test - performs the upgrade and downgrade 
 command on the given database
   update_db_from_model - modify the database to match the 
 structure of the current MetaData
   upgrade  - upgrade a database to a later version
   version  - display the latest version available in 
 a repository
   version_control  - mark a database as under this 
 repository's version control
 
 
 
 python-migrate's 'create_model' does not however give you something that 
 exactly matches the schema you'd get by running the all the migrations. So 
 auto generation doesn't appear to be an option right now. It would be nice to 
 contribute python-migrate in this regard and get better support for model 
 generation, etc. Maybe a good long term goal?

Hi Dan,


Le vendredi 27 avril 2012 à 08:28 -0700, Dan Wendlandt a écrit :



 
 Which mode are you running OVS in?  VLAN or tunneled?  If you are
 using VLAN-mode (default) you need to add some physical interface to
 br-int, so that VLANs are trunked to the physical network.  Is it
 possible that eth1 was also the interface you were using for IP
 communication on the box?  That definitely won't work with OVS or the
 linux bridge.  I'll improve the docs around that to make this more
 clear.  
 


I'm using default mode : VLAN.


 
 
 
 Can you ping me with the error messages (can be offlist)?  I still
 don't understand what you misconfigured, or how you fixed it.  


I actually had an issue when I executed : ovs-vsctl add-port br-int eth1

I checked on the log and could see that Quantum-Agent didn't start.
After inverstigation, it's seem that it was looking for a free physical
interface to bridge. I released eth1 and all worked very good.


 
 
 Great to hear.  As I mentioned in a previous post, Horizon + Quantum
 isn't complete.  You won't be able to create networks using Horizon,
 or boot VMs while specifying a particular set of vNICs.  If you're
 interested in helping this work move forward more quickly, I'm happy
 to put you in touch with the right people.  
 


Of course I am !

I'm writing a documentation to install OpenStack Essex from scratch with
Ubuntu 12.04 with Quantum  OVS. I will to release it soon :-)

[Openstack] Periodic clean-up of fixed_ip addresses in multi-host DHCP mode

2012-04-27 Thread Day, Phil

Hi Folks,

In multi-host mode the host field of a network never seems to get set (as 
only IPs are allocated, not networks)

However the periodic revovery task in NetworkManager uses the host field to 
filter what addresses it should consider cleaning up (to catch the case where 
the message from dnsmasq is either never sent or not delivered for some reason)

if self.timeout_fixed_ips:
now = utils.utcnow()
timeout = FLAGS.fixed_ip_disassociate_timeout
time = now - datetime.timedelta(seconds=timeout)
num = self.db.fixed_ip_disassociate_all_by_timeout(context,
   self.host,
   time)
if num:
LOG.debug(_('Dissassociated %s stale fixed ip(s)'), num)


Where db.fixed_ip_disassociate_all_by_timeout   is:

def fixed_ip_disassociate_all_by_timeout(_context, host, time):
session = get_session()
inner_q = session.query(models.Network.id).\
  filter_by(host=host).\
  subquery()
result = session.query(models.FixedIp).\
 filter(models.FixedIp.network_id.in_(inner_q)).\
 filter(models.FixedIp.updated_at  time).\
 filter(models.FixedIp.instance_id != None).\
 filter_by(allocated=False).\
 update({'instance_id': None,
 'leased': False,
 'updated_at': utils.utcnow()},
 synchronize_session='fetch')
return result


So what this seems to do to me is:

-  Find all of the fixed_ips which are:

o   on networks assigned to this host

o   Were last updated more that Timeout seconds ago

o   Are associated to an instance

o   Are not allocated

Because in multi-host mode the network host field is always Null, this query 
does nothing apart from give the DB a good work out every 10 seconds - so there 
could be a slow leakage of IP addresses.

Has anyone else spotted this - and if so do you have a good strategy for 
dealing with it ?

It seems that running this on every network_manager every 10 seconds is 
excessive - so what still running on all netwok_managers but using a long 
random sleep between runs in mult-host mode ?

Thoughts ?

Cheers,
Phil

Hi Leander,

Looks like a misconfiguration. The base path for nova's instances is 
typically /var/lib/nova/instances, set by the instances_path 
configuration option.


Somehow it is being set to /usr/lib/python2.7/dist-packages/instances, 
which is clearly incorrect.


How did you install your Nova code?

Re: [Openstack] Code contribution

2012-04-27 Thread John Postlethwait

If you are asking how it becomes approved the answer is that two 
core-contributors of the specific project need to manually review the code, and 
+2 it. When that is done, Jenkins, a CI tool, will run the various automated 
acceptability tests against the code and if they all pass, it will merge it in 
to the project.

[Openstack] Checking InnoDB table creation as part of unit tests for nova

2012-04-27 Thread Sean Dague

I've got a patch out for review that opportunistically tests the nova 
migrations on mysql, if a very specific mysql database name/password/db 
exists on the test system (fails gracefully if it doesn't). It then also 
checks to make sure that there are no non-InnoDB tables in the 
resultant migration (also failing gracefully if there isn't). We did a 
couple of draft reviews with the CI team to make sure this was something 
they could support as a gating test. This would prevent new migrations 
that don't specify engine from sneaking in.


I'd like feedback from Nova devs on the approach - 
https://review.openstack.org/#/c/6805/

comments, flames, etc are welcome.

Thanks,

-Sean

Re: [Openstack] Proposal for manuals translation process

2012-04-27 Thread Anne Gentle

Hi Daisy,

Thanks so much for this detailed proposal. I'd like you to put it on the
OpenStack wiki, at http://wiki.openstack.org/Translations.

My first read-through and discussion with the CI team brings up a few
comments:
- Whatever we do for docs, we should also do for code strings. So
unfortunately the scope for the Goal probably cannot be so narrow. We
know Launchpad to be broken with code strings now, that data point should
be reflected in this point-in-time analysis.

- Dashboard uses Transifex now (while the other projects unsuccessfully use
Launchpad). Tres Henry, can you comment on the number of translators of
Dashboard strings you have on the Transifex side already?

- Not that I want analysis paralysis, but, we may need to add a third
column of a crowd-sourced translation option like Pootle that is familiar
to open-source translators. Also, the lack of a translation
memory/dictionary (and having to hold such a valuable asset in a wiki page)
is troubling, can we also analyze an option that offers a translation
dictionary? So much re-use would be available to all the projects.

- There seems to be assumptions that Jenkins and Gerrit will just work
with out much description of the role those two crucial tools play. Can you
further describe the workflow for those in the Slicing, Uploading,
Downloading, Converging, and Generating steps?

I appreciate all the hard work I _know_ went into this proposal. Let's get
it on the wiki, discuss more, and keep adding details. I'd like to make
this a blueprint, could be for openstack-manuals, could be for horizon, I
don't know yet. Thanks for stepping up and embracing our international
community's needs!

Thanks,
Anne

 Hi, all

 During the I18N in OpenStack discussion in design summit, it is
 mentioned that documents need to I18N. I also noticed some requests for a
 Chinese version manuals from China users. But unlike Gettext strings in the
 codes,  there is no process for DocBook translation yet. Translators, who
 want to help translation, have to take a DocBook into a tool and perform
 a translation on a copy which will be saved as a new file. This
 traditional translation model is not good for collaboration. Usually, the
 open source translation depends on volunteers. It's better to use the crowd
 translation model, which enables a mass of translators to work on the
 same job, just like the Launchpad Web UI for Gettext strings translation,
 any people can jump in at any time and contribute to any part of the
 translatable contents.

 In order to facilitate the manuals translation, I investigated several
 translation websites and several open source projects. I composed this
 proposal. Now it's open for suggestions and comments.

 *Goal*
 **
 A process for manuals translation

 *Background*
 *--*
 OpenStack Manuals are in DocBook format. The source is on GitHub:
 http://github.com/openstack/openstack-manuals
 Launchpad and Transifex are free web based tools used for crowd
 translation. Both of them provide a simple web interface in which
 non-technical people can help translation. They don't support DocBook
 format, but support the popular GNU Gettext file formats (PO Template or
 PO).

 *Translation Process*
 *---*
 In order to translate OpenStack Manuals to multiple languages, which are
 in DocBook format, we can slice the documents into short statements, then
 use a web based translation management tool to manage the translation
 process, and finally converge the translated content into a new copy of
 DocBook.

 Here are the five steps of the translation process:
 Step #1 Slicing - extract translatable content from DocBooks and generate
 Gettext compatible POT files (PO Template or PO);
 Step #2 Uploading - upload the POT (or PO) files to a web based
 translation management tool;
 Step #3 Downloading - download PO (or MO) files from the web tool after
 translation and review;
 Step #4 Converging - converge the translated contents into new copies of
 DocBook, create DocBooks in multiple languages
 Step #5 Generating - generate HTML/PDF in multiple languages from DocBooks
 in multiple languages

 The picture in the attachment describes these steps.
 *(See attached file: DocBook translation process.png)*

 *Compare of Launchpad and Transifex*
 *---*
 Launchpad (https://launchpad.net/) and Transifex (
 https://www.transifex.net/) are similar web based tools used for crowd
 translation. The goal of the compare is to find the most appropriate tool
 for this scenario. The compare are made between Launchpad and Transifex
 free version for open sources. (Refer to https://www.transifex.net/plans/ to
 get details of “Transifex free version for open sources”)

 After considering the requirements for manuals translation,  below
 perspectives are taking into consideration:
 *Supported format
 *DocBook slicing support
 *Converging

Looks like your instances_path flag is pointing to python's dist packages

Re: [Openstack] Mailing-list split

2012-04-27 Thread Everett Toews

I like this idea but what happens to the openstack-operators list in this
scenario?

I don't think we'd want to have the openstack and openstack-operators list
going along in parallel since it sounds like they would overlap. I propose
that the members of the openstack-operators list would be (automatically or
manually) migrated to the openstack list. Then the openstack-operators list
would be set to read-only or maybe even removed completely to avoid
confusion.

Comments? Feedback?

 Hello everyone,

 TL;DR summary:
 Due to traffic exploding, we will split the current openstack list into
 user / usage topics (openstack list) and development / next-version
 topics (openstack-dev list).

 Long version:

 At the Communication session at the design summit [1] we looked at the
 state of our communication media in general, and mailing-list in
 particular [2].

 [1]

 http://folsomdesignsummit2012.sched.org/event/366accca0fda271fc23e82b9cb5162cc
 [2] http://etherpad.openstack.org/FolsomCommunication

 The traffic on the openstack@lists.launchpad.net list doubled in the
 last 4 months [3], with more users and deployers asking for information
 on OpenStack projects. It becomes difficult for contributors to properly
 prioritize their ML reading, and we can no longer have all the
 discussions in the same place.

 [3] http://openstack.markmail.org/

 The proposal is to split between:

 1/ Usage, deployment, Essex / current-stable discussions
 2/ Development, contribution, Folsom / forward-looking discussions

 A new list will be created for (2) and existing contributors will be
 asked to subscribe to that new list.

 Since we expect to have a more disciplined/focused group in that new
 list, we'll define a set of subject prefixes that should be used for
 easier client-side/at-a-glance filtering of discussions:

 [General] Affects all projects
 [Swift] [Nova] [Glance] [Quantum] [Horizon] [Keystone] Project-specific
 [Common] openstack-common
 [QA] [CI] [Docs] Discussions / Information on specific topics
 [...] Add your own here

 To keep that list usable, I suggest we aggressively enforce those topics
 and redirect inappropriate discussions to the other list when necessary.

 To avoid Launchpad list slowness, we would run the new openstack-dev
 list off lists.openstack.org. Given the potential hassle of dealing with
 spam and delivery issues on mission-critical MLs, we are looking into
 the possibility of outsourcing the maintenance of lists.openstack.org to
 a group with established expertise running mailman instances. Please let
 us know ASAP if you could offer such services. We are not married to
 mailman either -- if an alternative service offers good performance and
 better integration (like OpenID-based subscription to integrate with our
 SSO), we would definitely consider it.

 There was a suggestion during the session of using umbrella/siblings
 lists to aggregate content from multiple project-specific sublists. I
 reviewed the options and I think it introduces a lot of complexity,
 reduces flexibility in adding new topics, so client-side filtering
 sounds like a better bet. If most people use subject prefixes
 appropriately, keeping it simple is probably the best bet.

 We'll let you know when the new list is set up.

 Regards,

[Openstack] [QA] Summary of QA Weekly Status meeting

2012-04-27 Thread Jay Pipes

The QA team had its weekly IRC meeting yesterday. Here is a summary of 
the action items and decisions coming out of the meeting.


* Progress

 - Currently up to more than 150 integration tests

 - The dev-gate-tempest-devstack-vm Jenkins job [1] has run smoothly 
now for a number of iterations. There are still some issues with the job:


  - The job takes more than 40 minutes to complete on *some* cloud 
providers. Most of this time is taken by devstack installing the 
OpenStack environment via devstack into the utility VMs

   - Jim Blair upped the timeout to 60 minutes to help this problem
  - 2 test failures are consistently reproduceable
   - Working to fix both by end of week
 - Jim Blair added a nice report output [3] to the Jenkins job 
utilizing the nosetests xUnit output plugin (thank you Jim!)


* Action items

 - (jaypipes) Get dev-gate-tempest-devstack-vm Jenkins job [1] gating 
Tempest by end of week


* Decisions made

 - Going to start a rotating QA captain role [2] that is responsible 
for communicating an agenda for the weekly status meeting and a summary 
like this one for the meeting


* Blockers identified

 - Inclusion of python-glanceclient package in devstack has caused 
issues in the gating job. jaypipes working on fix for it with bcwaldon 
and dtroyer.


* Outstanding Reviews

Community, please feel free to provide code reviews on outstanding 
Tempest merge proposals:


https://review.openstack.org/#/q/status:open+project:openstack/tempest,n,z

Thanks!

Re: [Openstack] Unable to download images using Glance+Keystone+Swift

2012-04-27 Thread Lillie Ross-CDSR11

DOH! (boy I say this a lot…)

As usual, a stupid configuration error. In my old Diablo setup, the
administrative role was specified via the keyword Admin. I imported the
existing user accounts, tenants, and roles into my Essex test setup. However I
neglected to set the Glance 'admin_role' configuration flag, so it defaulted to
the keyword admin. Once I fixed this, image downloads are working fine and
instances boot with no problem.

Congrats to everyone that pulled Essex together. Overall stability and
functionality is much improved. We'll be migrating our Diablo cloud to Essex
over the next week.

 If you are asking how it becomes approved the answer is that two
 core-contributors of the specific project need to manually review the code,
 and +2 it. When that is done, Jenkins, a CI tool, will run the various
 automated acceptability tests against the code and if they all pass, it will
 merge it in to the project.

 I like this idea but what happens to the openstack-operators list in this

 I don't think we'd want to have the openstack and openstack-operators list
 going along in parallel since it sounds like they would overlap. I propose
 that the members of the openstack-operators list would be (automatically or
 manually) migrated to the openstack list. Then the openstack-operators list
 would be set to read-only or maybe even removed completely to avoid
 confusion.

 Comments? Feedback?

 Hello everyone,

 TL;DR summary:
 Due to traffic exploding, we will split the current openstack list into
 user / usage topics (openstack list) and development / next-version
 topics (openstack-dev list).

 Long version:

 At the Communication session at the design summit [1] we looked at the
 state of our communication media in general, and mailing-list in
 particular [2].

 [1]

 http://folsomdesignsummit2012.sched.org/event/366accca0fda271fc23e82b9cb5162cc
 [2] http://etherpad.openstack.org/FolsomCommunication

 The traffic on the openstack@lists.launchpad.net list doubled in the
 last 4 months [3], with more users and deployers asking for information
 on OpenStack projects. It becomes difficult for contributors to properly
 prioritize their ML reading, and we can no longer have all the
 discussions in the same place.

 [3] http://openstack.markmail.org/

 The proposal is to split between:

 1/ Usage, deployment, Essex / current-stable discussions
 2/ Development, contribution, Folsom / forward-looking discussions

 A new list will be created for (2) and existing contributors will be
 asked to subscribe to that new list.

 Since we expect to have a more disciplined/focused group in that new
 list, we'll define a set of subject prefixes that should be used for
 easier client-side/at-a-glance filtering of discussions:

 [General] Affects all projects
 [Swift] [Nova] [Glance] [Quantum] [Horizon] [Keystone] Project-specific
 [Common] openstack-common
 [QA] [CI] [Docs] Discussions / Information on specific topics
 [...] Add your own here

 To keep that list usable, I suggest we aggressively enforce those topics
 and redirect inappropriate discussions to the other list when necessary.

 To avoid Launchpad list slowness, we would run the new openstack-dev
 list off lists.openstack.org. Given the potential hassle of dealing with
 spam and delivery issues on mission-critical MLs, we are looking into
 the possibility of outsourcing the maintenance of lists.openstack.org to
 a group with established expertise running mailman instances. Please let
 us know ASAP if you could offer such services. We are not married to
 mailman either -- if an alternative service offers good performance and
 better integration (like OpenID-based subscription to integrate with our
 SSO), we would definitely consider it.

 There was a suggestion during the session of using umbrella/siblings
 lists to aggregate content from multiple project-specific sublists. I
 reviewed the options and I think it introduces a lot of complexity,
 reduces flexibility in adding new topics, so client-side filtering
 sounds like a better bet. If most people use subject prefixes
 appropriately, keeping it simple is probably the best bet.

 We'll let you know when the new list is set up.

 Regards,

 --

If there has been some work done towards this, i would be very interested

If not, I will take on part of this blueprint and contribute it.

 I like this idea but what happens to the openstack-operators list in this
 scenario?

 I don't think we'd want to have the openstack and openstack-operators list
 going along in parallel since it sounds like they would overlap. I propose
 that the members of the openstack-operators list would be (automatically or
 manually) migrated to the openstack list. Then the openstack-operators list
 would be set to read-only or maybe even removed completely to avoid
 confusion.

 Comments? Feedback?

Hrm. One of the things that came out of the Design Summit discussions
around DevOps was that the OpenStack DevOps sub-community doesn't
really feel like it has a voice. As a result, I'd be loathe to remove
that venue for discussion right now, even if it's only of symbolic
value.

That being said, I propose that something along the following lines
could happen:
 * intense dev work, collaboration, etc., happening on openstack-dev@
 * general usage of openstack questions by folks who are not code
contributors, but standing up OpenStack itself, happening on
openstack@
 * conversations around DevOps in particular (the wide spectrum of
definitions that comprise DevOps in various people's minds)
happening in openstack-operators@

In helping jump-start (or re-jump-start) the OpenStack DevOps
community, I'd really like to have a dedicated place for
announcements, questions, etc. Even if we spent some time pointing
folks to more detailed, technical resources.

In hallway conversations at the summit (and in various emails and
phone calls since then), people who consider themselves DevOps have
expressed concern over the possibility that the operators list would
go away. They are overwhelmed by the volume of traffic on the
openstack list, and don't have the time to devise a solution for
creating appropriate filters, etc.

That objection may simply go away with the new mail list split.

But if openstack-operators has become a property valuable to community
members, we shouldn't just get rid of it because it doesn't make
logical sense. We should make sure that folks are ready to transition
to another location for their DevOps needs.

And that might take a cycle to sort out...

Re: [Openstack] OpenStack Quantum plugins

2012-04-27 Thread Salman Malik


Hi Dan,

Thanks for replying. There are few more questions:
 


I am trying to learn the functionality of Quantum plugins used in 
OpenStack. I have read through the Quantum Admin Guide and had few 
basic/quick question about quantum and OVS interaction with it:




1) OVS can have ports in which vNICS can be plugged, so why does it need
 to use an integration bridge for connecting all VMs on the same node to
 a network?

I'm not sure I follow what question you're asking.  When OVS is running on a 
host, it has one or more bridges, and bridges have ports.  A linux device 
representing the vNIC must be added as a port of a bridge being managed by the 
Quantum plugin.  We call this bridge the integration bridge.   The Quantum 
plugin can then configure the ports and bridges appropriately to forward 
traffic based on the logical model created via the Quantum API.  Can you be 
more precise about what you're asking here? 


In short it means that the OVS is managing the linux bridges and the linux 
devices representing vNICs must be added to these bridges (Does Quantum manager 
adds these devices to bridges?). And when you say that quantum plugin 
configures the ports and bridges appropriately to forward traffic, you mean 
that it updates the database and then quantum agent then assures the correct 
mapping of ports/network ids to logical networks at the switch level(by adding 
flow entries to vSwitch? or by adding the vNICs to right bridges, as there is 
one bridge per tenant's network on compute node). Right?
 


2) The OVS quantum plugin seems to implement the core API functions and 
(viewing the code) I concluded that it just makes maintains the logical 
mappings e.g. b/w net IDs and VLAN IDs in a database. So how is this 
mapping implemented on the actual ports of OVS? Is it the OVS quantum 
agent responsible for directing the packets to correct input/output 
ports based on the updates that it gets from the database?

In VLAN-mode, its even simpler than that.  The agent simply puts each port as a 
VLAN access port for the right VLAN, based on the database, and then has OVS 
perform standard L2 learning to forward packets.  

 
good to know.




3) The quantum admin guide says that the nova client will be the main
 user of quantum and will interact with it via REST API, so it would be nice if 
someone can point me to the code (file path name etc.) where this happens.

This is the QuantumManager code in Nova: 
https://github.com/openstack/nova/tree/master/nova/network/quantum


One word of warning: this code will be being simplified and largely removed in 
Folsom, so while its useful to look at it to learn about Quantum, I'd ask 
around before investing the time to make significant changes to the code.  



PS: What is the purpose of Quantum Manager in this architecture and where 
should I look for its code? 



Thanks for the reference. I have looked at the code and just to affirm my 
understanding please confirm/correct/answer the following:
Quantum manager is responsible for configuring the network for new instances 
that spin up. When a tenant adds a port to his logical network the request will 
be forwarded to this manager by Nova and then Manager (using quantum client) 
would talk to quantum service/server (where can I see its code?) with the REST 
API. According to documentation, the quantum service is responsible for loading 
the plugin and passing the REST API calls to the plugin. The plugin then 
updates the database. Rest of the work is done by quantum agent.

see above :)
Thanks again for clarification. Since, I am still trying to understand the data 
flow, please pardon me for questions that are confusing.
Salman

Re: [Openstack] OpenStack Quantum plugins

2012-04-27 Thread Salman Malik


Hi Hitesh,
Thanks for the considerate reply.
Please see the inline comments.

On Fri, Apr 27, 2012 at 1:25 AM, Salman Malik salma...@live.com wrote:

1) OVS can have ports in which vNICS can be plugged, so why does it need to use

[Hitesh]:
As far as I know that OVS have more features over the Linux bridge, for 
example, VM isolation, mobility and security. These can be configured by remote 
controller. To help and gian the control on all these activities the 
integration bridge is required. I am not sure about it but I Dan or Salvotore 
can explain this better way. You can find the more information here 
http://openvswitch.org/support/

Now, what I have understood from Dan's reply is that OVS itself consists of 
these bridges (each bridge on a node, being called as an integration bridge). 
Correct me if I am wrong.


  
2) The OVS quantum plugin seems to implement the core API functions and 
(viewing the code) I concluded that it just makes maintains the logical

[Hitesh]:
OVS agent is responsible for to update the database(accoding to actions have 
been told) for the local server as well Quantum server. As far as I know OVS 
quantum is not responsible for directing the packets to correct in/op,  This 
job is hadled by OVS core module on the server (datapath). OVS agent only 
updates the database and creation bridge etc.. Dan or Salvotore can be 
explained more...


Are you sure that quantum agent updates the database? I used to think that it 
only grabs updates by looking into the database (which is actually modified by 
the plugin). I am not sure so just confirming.

3) The quantum admin guide says that the nova client will be the main user of 
quantum and will interact with it via REST API, so it would be nice if someone 
can point me to the code (file path name etc.) where this happens.


[Hitesh]:
You can see the devstack script where we are configuring nove-network to 
quantum. thats the enry point for the nova-network to communicate to quantum. I 
will share soon more on this.

Thanks Hitesh for sharing you knowledge :) Can you comment on how nova-network 
interacts with Quantum-manager?

 
However, I tried my best to give to these answers. Please feel free to correct 
me if anything needs to share more.
 
Salman, Let me know if you want more info about this. I will be happy to share


Thanks again Hitesh. I appreciate your help.
Salman

 Hi Leander,

 Looks like a misconfiguration. The base path for nova's instances is
 typically /var/lib/nova/instances, set by the instances_path configuration

 Somehow it is being set to /usr/lib/python2.7/dist-**packages/instances,
 which is clearly incorrect.

 How did you install your Nova code?

We should make one small change at the time, measure/evaluate and keep
