Re: [Openstack] instance metadata timeout

[Dan Wendlandt]

Hi Naveen,

There are probably a couple of things going on here.

1) When using quantum, the L3 forwarding + NAT are actually handled by
the quantum-l3-agent, not nova-network (in fact you shouldn't run
nova-network at all when you're using Quantum in Folsom).  You should
make sure the l3_agent.ini have metadata_ip and metadata_port
configured to map to your nova-api server and port.

2) The quantum-l3-agent supports the creation of many routers each
with potentially overlapping IPs on a single linux host using network
namespaces.  This is the default configuration, but it creates several
complications when working with nova's metadata server, which assumes
a pretty simple network model with a single router.  quantum-l3-agent
can run in a mode more akin to nova's L3 model by disabling namespace
setting use_namespaces=False in the l3_agent.ini .  Beware that doing
so will mean all configuration of routes done by the quantum-l3-agent
will affect data forwarding for the entire host (i.e., it may steal
your default route).  Running quantum-l3-agent with namespaces
disabled and running nova-api on the same host should map to the more
traditional nova-network setup.

Are you using devstack?  If so, I think there are some changes we
should make to devstack to make it easier to use Quantum in a fashion
that maps to traditional nova networking for L3 + NAT.  I've heard
others mention that they are confused about why the default Quantum
setup does not let them SSH directly to VMs via their fixed IPs, and
the use of namespaces is the root cause for this as well.  Will post a
possible patch for this soon.

Dan

[Openstack] Adding new method to nova API throws exception

[Trinath Somanchi]

Hi Stackers-

I'm working on currently adding an additional method to the NOVA API.

The new method groups the servers based on the metadata. It returns a group
of server UUIDs based on the Metadata information in the URL from client.

For the same I have modified the following files.

[1] update the nova.api.openstack.compute.__init__.py with the following
mapper.resource.

  mapper.resource(server,servers,
controller = self.resources['servers'],
collection={'metadetail':'GET'},
member={'action':'POST'})

[2] Update the nova.api.openstack.compute.servers.py with the following
function

 @wsgi.serializers(xml=ServerTemplate)
 def metadetail(self,req):
 Return the servers UUIDs based on the META data infortmation 
return;

Being a newbee to understand the code well, I have updated the novaclient
api, to redirect the request to /server/metadetail/{metadata_details}

But the approach was unsuccessful.

Thank you for your suggestion!

Running ./manage.py compress
compresses some sources, obviously, some are not compiled:

You have offline compression enabled but key

may need to run python manage.py compress.

For at least Debian, this would make the package

If you can't compile it yourself then you could perhaps use the one from
Adam/Ubuntu, or I can do it and send you the final output file.


IMHO, it still should be usable for debian as well, sources are still 
shipped; the step you do is pre-compressing stylesheets, and javascript 
so this hasn't be done during delivering files through your web server.


But of course, I'm totally neglecting that less.js and node.js may not 
be available in your distro, like they are unavailable from official 
fedora repositories

Hi Stackers,

Do we have any docs/information on per-net-dhcp-enable feature in Quantum
v2.0.?

Please share with us.

As it is observed that using folsom-3 releases, we didnt see any DHCP
services enabled by default. Do we still have issues with quantum v2.0
w.r.t DHCP !!

Re: [Openstack] per-net-dhcp-enable in quantum v2.0

[Salvatore Orlando]

Hi Balaji,

Quantum now has a dhcp agent which serves addresses to subnets using
dnsmasq.
The dhcp agent is a separate binary (bin/dhcp-agent). per-net-dhcp-enable
has been translated into a simple feature that enables or disables the dhcp
agent for specific subnets.
This is controlled by the Quantum API with the enable_dhcp flag on the
subnet object.

Documentation concerning configuring and running the DHCP agent is in
preparation and will be published soon.
Documentation on Quantum v2 API is available at
http://docs.openstack.org/api/openstack-network/2.0/content/

Regards,
Salvatore

 Hi Stackers,

 Do we have any docs/information on per-net-dhcp-enable feature in
 Quantum v2.0.?

 Please share with us.

 As it is observed that using folsom-3 releases, we didnt see any DHCP
 services enabled by default. Do we still have issues with quantum v2.0
 w.r.t DHCP !!

Re: [Openstack] AMQP---2 queues for nova-compute?

 Hi,all

 Thanks a lot.

I don't think that the 'compute' queue is actually used.  It's there
because the code that sets up the queues is common to all nova services,
so they are all capable of the same set of messaging patterns.

All instances of nova-compute are subscribed to the 'compute' topic.  If
a message were to be sent to that topic, it would go to one instance of
the services, chosen via round-robin.

A realistic example of the use of this topic is the nova-scheduler
service.  Messages to the scheduler are sent to the 'scheduler' topic.
You can run multiple instances of nova-scheduler to scale it out, and it
doesn't matter which one processes each scheduler request.

Re: [Openstack] strange problem when reboot nova-compute node: domain not found: no domain with matching name

[romi zhang]

Razique,

 

Additional information:

Another testing system was not full of testing job. I met this problem
before at my small system. If I use ubuntu image download from network,this
problem was not happened. If I use centos and windows image create
instance,this problem will happened,and in the process of building centos or
windows instance, nova-compute always promote: libvirt qemu error,domain not
found. But finally instance would run normally, and then to reboot the host
of nova-compute and then run nova-compute ,it would stop at :CRITICAL error:
libvirt qemu error, domain not found,…..

Razique,

 

Appreciate for your attention.

 

# ls /etc/libvirt/qemu/networks/autostart

default.xml

 

at my memory,when the first time I computed the system installation, reboot
compute-node have no problem, and then after I created centos and windows
instances (in the booting process,system show :libvirt qemu error: domain
not found) and reboot one of compute-nodes ,nova-compute stopped and show me
: CRITICAL error, Libvirt: QEMU error: Domain not found: no domain with
matching name ‘instance-000a’. then the others also have same problem.

 

At my corner,it is a sysmatic behavior.

 

But at my another testing system, this problem had not happened.

Hey, 

could you remove the flag :

--resume_guests_state_on_host_boot=true

ans restart the nova-compute service 

 

Can you run

$ ls  /etc/libvirt/qemu/autostart 

 

Does that behaviour is systematic ? Everytime you restart the service
nova-compute, or do you need to also have your compute node restarted ?

Is there anything should be cared with image? It looks like related with the

Re: [Openstack] question about multi-host network configuration

[Narayan Desai]

Sure, we've been running in that sort of configuration since bexar.
The only tricky part is that you need to make sure that you run
nova-api-metadata on each nova-network server, and you need to make
sure that floating IPs can get to the appropriate fixed addresses (ie
if a fixed address is not routed from the nova-network instance where
the floating address is served from). That last bit pretty much
requires setting up something like ospf for route exchange between
your nova-network servers. (fixed networks aren't pegged to one n-net
instance or the other, so they can move over time)

Re: [Openstack] Packaging Horizon

[Clint Byrum]

Excerpts from Gabriel Hurley's message of 2012-09-14 20:40:25 -0700:
 Now I'm not well-versed in the legalese of all the distros, but that sounds 
 like splitting hairs on the meaning of compiled from source. If I run it 
 through LESS and commit the file to the repo does that make it from source? 
 It'd solve your problem exactly the same.
 
 I'd be curious to know the definition here, but that seems like overkill to 
 me. If its what you need I'll do it for Folsom, but... thoughts?

The reason this is important is that one of Debian's main purposes for
being is that you can solve your problems with nothing but the archive. If
there is a problem in said CSS/JS generated by LESS, then a user cannot
easily 'apt-get source horizon', edit the file, and be on their way. They
really need the source code and a way to regenerate the compiled bits.

Seems to me that packaging LESS would be pretty easy though, so I don't
think this will be an issue in the long term. Including the compiled
one is just a short-term solution.

Re: [Openstack] Cells Status

I agree it's disappointing that it's not in trunk yet… and it needs to get in 
there ASAP.  I'm definitely happy to hear that others have been doing a bit of 
hacking on it, wrt security groups and so forth! 

I just got back from 2 weeks of vacation and I need to get my branch rebased.  
There's a couple of things broken because of RPC versioning bumped to 2.0, etc, 
as well… 

In any case, it's definitely my plan to get this into trunk extremely soon

 It would be good to get this in master as soon as Folsom gets branched off as 
 we'd like to contribute these back.
 
 
 Cheers,
 Sam

 on this. 
 
 Can we try with the patch listed below. Only one concern with patches are we 
 dont get much help from stack users/testers..
 
 This is little disappointing...

 Ya, is there a session on it at the summit.
 
 I'd at least like to talk about it and what it could be in the end.
 
 Or maybe we can 'freestyle' that session :-P

  This is very disappointing. I was looking forward to cells as well.
 
  When was this decided and was the decision announced somewhere else? I'd
  like to know so I can monitor for other announcements like this.
 
 The patch is here:
 
 https://review.openstack.org/#/c/10707/
 
 It was proposed for inclusion on August 2nd, which was just a couple of
 weeks before the feature freeze.  There were enough significant things
 that came up in discussion that it just wasn't going to make it in for
 Folsom.  In addition to working through the technical details, it also
 desperately needs some documentation (ideally both architectural, as
 well as how to use it).
 
 It seems like we should be able to get this all wrapped up for Grizzly,
 though.

Lauren,

Thank you for getting this setup. I can confirm that there are some rooms free 
as I just took three :)

See you all in San Diego.

It's been difficult to find more rooms at a reasonable rate because there are a 
few other big conferences in town that week, but the Hard Rock Hotel had a big 
group cancel. The have rooms available for $249, and it's 4-5 blocks from the 
Hyatt down Harbor Drive.  We do not have an official contract, but they set up 
a courtesy block and said they would keep us up to date on availability:

Hope this helps, or please let everyone know if there are better rates/options 
available.

There are no plans at the moment to  contract more block rooms but we
may go out and scout some recommendations for you... If you have a
favourite place or get started with your personal research please share
the findings with us.

[Openstack] TC candidacy

[Chris Behrens]

Hi all,

I'd like to announce my candidacy for a seat on the OpenStack
Technical Committee.

- General background -

I have over 15 years of experience designing and building distributed
systems.  I am currently a Senior Software Developer at Rackspace,
where I have been for a little over 2 years now.  Most of my time
at Rackspace has been spent working on OpenStack as both a developer and
a technical leader.  My first week at Rackspace was spent at the very first
OpenStack Design Summit in Austin where the project was announced.

Prior to working at Rackspace, I held various roles over 14 years
at Concentric Network Corporation/XO Communications including Senior
Software Architect and eventually Director of Engineering.  My main
focus there was on an award winning web/email hosting platform which
we'd built to be extremely scalable and fault tolerant.  While my
name is not on this patent, I was heavily involved with the development
and design that led to US6611861.

- Why am I interested? -

I have strong feelings for OpenStack and I want to help take it to
the next level.  I have a lot of technical knowledge and experience
building scalable distributed systems.  Having finished helping
launch a large deployment of OpenStack at Rackspace on 8/1, I have the
time and support to start making a larger contribution to the community.

During most of my past experience, I haven't had the luxury of having
access to a lot extremely fast hardware, so it's been important to
make software as performant as possible.  I've also had to put lots of
effort into having 0 downtime, meaning code can be updated seamlessly
without dropping clients.  I've also been one to lead host and software
security efforts so I have a lot of strong feelings in this area.

I am extremely interested in using this experience to make OpenStack
perform well, be secure, be more easily pluggable, and easy to use!

- Relevant Private Source Experience -

Unfortunately XO was not very big on open source, so there's a lot
of innovative work that I have not been able to publish.  But, I've
worked on such things as developing multithreaded DNS and MX (mail)
servers from scratch.  The latter work is notable as it allowed scaling
to tens of thousands of simultaneous socket connections to a single mail
server, allowing us to be very efficient hardware wise.

- Open Source Experience -

My initial contributions to open source software date back to 1994,
working on EFNet's IRCD daemon, submitting performance improvement
patches and features to help EFNet grow to over 100,000 simultaneous
clients.  Starting in 1998, I rewrote the daemon to make it scale
even further, also adding in support for dynamic upgradeability
(code upgrades without dropping clients).

- OpenStack -

As I mentioned above, I was at the very first design summit, so
I've been involved with the project from the beginning.  I started
the initial work for nova-scheduler shortly after the project was
opened.  I also implemented the RPC support for kombu, making sure
to properly support reconnecting and so forth which didn't work
quite so well with the carrot code.  I've contributed a number of
improvements designed to make nova-api more performant.  I've worked on
the filter scheduler as well as designing and implementing the
first version of the Zones replacement that we named 'Cells'.  Cells is being
used today in production at Rackspace, but it does need a bit of work to fit
into trunk (like documentation :).

- Summary -

I feel my years of experience contributing to and leading large scale
technical projects along with my knowledge of the OpenStack projects
will provide a good foundation for technical leadership.

Thanks,

- Chris

 Hi Stackers-

 I'm working on currently adding an additional method to the NOVA API.

 The new method groups the servers based on the metadata. It returns a
 group of server UUIDs based on the Metadata information in the URL from
 client.

 For the same I have modified the following files.

 [1] update the nova.api.openstack.compute.__init__.py with the following
 mapper.resource.

   mapper.resource(server,servers,
 controller = self.resources['servers'],
 collection={'metadetail':'GET'},
 member={'action':'POST'})

 [2] Update the nova.api.openstack.compute.servers.py with the following
 function

  @wsgi.serializers(xml=ServerTemplate)
  def metadetail(self,req):
  Return the servers UUIDs based on the META data infortmation
 
 return;

 Being a newbee to understand the code well, I have updated the novaclient
 api, to redirect the request to /server/metadetail/{metadata_details}

 But the approach was unsuccessful.
