Ugh... did anyone take pictures of the "easel work"? Or take (less old
fashioned) notes?

Re: [Openstack] Installion guide for OpenStack Essex on Ubuntu 12.04

[Shake Chen]

Hi Martin

Now the document seem have two problem. Hope you can fix and make it
perfect.

1:glance

Now the glance package have some change. for future upgrade reason, you
have to manual create glance database table.

https://bugs.launchpad.net/ubuntu/+source/glance/+bug/982787

you just need run

# glance-manage version_control 0
# glance-manage db_sync

then run glance index

working as expect.


2:vnc problem.

[Openstack] (no subject)

[clouder1]

Hi,
Apparently OpenStack essex release supports Rados Block Devices (RBD)
in nova-volume,however I was wondering what is the usability status of
these drivers?
Are the drivers complete, or even working? (I'm not saying they're
not, I'm just askingbefore venturing deep in trying).
While I've seen in the nova code some references/drivers to RBD, I
couldn't findany documentation on how to use it concretely. Is there
any howto or anywhere that I missed?
Is RBD supported at every levels in OpenStack?- glance store image
directly to RBD?- nova-volume creating RBD volumes? (apparently
supported)- nova-compute spawning RBD-backed VM instances using
libvirt+KVM?
There was a "Ceph Lords" talk in California organized by
Ceph/DreamHost/OpenStack folks,however I could not find any PDF
downloadables for those who could not attend..
Any pointer would be greatly appareciated. Thanks

Regards,James

[Openstack] quantum UI in essex

[Yi Sun]

Hi,
I'm using dev stack and I have enabled Quantum. Now, I can see the 
quantum service is running and I can also create network with CLI.
But I can not find any quantum related configuration UI from dashboard. 
Looking at the essex release note from this link ( 
http://wiki.openstack.org/ReleaseNotes/Essex#OpenStack_Dashboard_.28Horizon.29), 
it seems that the quantum support in Horizon has been disabled. Is there 
a way to re-enable it in my devstack environment?

Thanks
Yi

[Openstack] [Openstack:Summit] Nova Volume Unconference sessions

[John Griffith]

All,
For those of you that attended the Volume sessions at the summit this
morning (and those who may have missed it but would like to attend),
I'd like to continue our discussion tomorrow afternoon using the
Unconference sessions.

We've reserved 14:00 - 15:00 for continuation of the Volume spin out
discussion and 15:00 - 16:00 for Boot From Volume.  I'm working on a
specific set of goals/decisions to make during this time slots so that
we can begin moving forward and will have the etherpads updated
tomorrow.

Thanks,
John

Hey folks,

We don't seem to be giving the remote folks much love :-(

Quick fixes:
 * does someone have a link to all the etherpads for the sessions?
Let's get that emailed out to everyone
 * I'm going to start going around to each session and pasting info
into the channels for remote folks

Issues:
 * seems that the webex stuff isn't working consistently
 * sometimes audio isn't turned on
 * microphones aren't being passed around
 * there's no one appointed in the sessions to watch on IRC and pass
questions to the speakers

I'm sure there's lots of other issues...

Folks who are remote: this is only the second OpenStack conference,
and (I think?) this is the first time any sort of remote support has
been attempted. It's probably going to take a couple conferences to
get this ironed out.

Do note, however, that the IRC sessions are logged and will be combed
for problems, complaints, etc. I've already gone through them once
today, to see what I missed. Keep messaging, keep raising your
voices... you'll be heard eventually, and this will help make remote
support better with each conference.

See you online,

Re: [Openstack] Just JSON, and extensibility

[Caitlin Bestler]

ZFS feature flags are different on two important fronts.

First, they are binary. There is an intrinsic limit to the number claimable and 
no reason not to think that two project would not claim the same binary value.

More importantly, ZFS has a very specific challenge caused by Oracle 
maintaining their own closed source repository. There is a specific challenge 
in trying
To import a file system created under a closed repository to a file system 
built on the open repository (or vise versa).

Maybe I'm missing something, but where is the scenario for an openstack 
deployment that is built from mixed repositories?

It's easy when each new version is defined by a central body.

The problem we face is that we want to allow HP, Rackspace, Nexenta etc to 
define their own extensions, without serializing through a central body.  Some 
extensions may only apply to private clouds and never be shared publicly.

This is a bit like ZFS feature flags, to use an example that should be near and 
dear to your heart!

Exactly what do you see as the required "non-linear extensibility"?

These are ultimately requests to a server. Each new extension is coded in that 
server.
There is no value in a client making up its own extensions that are not 
understood by the server.

What is relevant is a server continuing to support clients that have not yet 
been updated to
understand a new format.

As I stated in my first post, that problem was solved in ANSI C. Python/JSON is 
trivial.

Note we're finalizing Essex packages within EPEL.
There is a preview repo available for dev testing,
with a README there detailing setup notes.

Yes please try it!

U will need EPEL for RH 6.2 but that is pretty standard.

That's great news Andy. It goes without saying (and it's already been said) 
that OpenStack integration is hugely important for the adoption of OCCI. 

Thanks for all your efforts and I can't wait to start using it!

Re: [Openstack] Open Cloud Computing Interface Blueprint Implementation

[Michel Drescher]

Dear Andy, all,

There is little left to say for me (thanks to others) but a wholeheartedly
"Bravo!" on the effort.

As Matteo and others have stated, it is important to have a publicly
defined standard being implemented in production grade software. But much
more important, certainly from an EGI perspective, is the availability of
*choice* of implementation for anyone who wishes to operate a Cloud
platform.

For us at EGI it is of particular importance as we are working towards a
production level federation of IaaS Cloud offerings, as a federation cannot
prescribe which particular software implementation to operate. With the
availability of OCCI in OpenStack, we now are in the place to actually see
our endorsement for OCCI to happen in in reality rather on paper.

What's more, native support for OCCI particularly makes the choice for
OpenStack attractive, as this means not only less operative service
management effort for a fronting proxy service (I hope!), but also, lets
say, less opportunity for configuration and operation mistakes. :-)

Cheers, and thanks again,
Michel

I think you shoud type screen -x stack
If -S, I believe a new stack screen session would start.

Also I remember that devstack runs its services on the account you ran stack.sh 
by default in the recent versions.

[Openstack] Essex on RHEL 6.2 and Cent OS 6.2

[Salman A Baset]

Hello folks,

Has anyone tried to install Essex compute, and cloud controller on RHEL 6.2
or Cent OS 6.2? Any experiences?

We tried to install Openstack Essex (2012) release on RHEL 6.2. Since there
are no packages ready for it, we tried to use Fedora 16, 17 and 18
packages. In all cases, we found that it not only requires a large number
of dependencies, as some of them are only available in the not yet released
RHEL 6.3 (like dnsmasq-utils), but that it also requires python 2.7.

Thanks.

You can restart services without reboot like this

sudo service nova-compute restart

Also according to documentation we can set flags in nova.conf using  
--= format. Is that an obsolete format ? (because  
the nova.conf that devstack creates don't have any -- in it).


Essex has new format for nova.conf without dashes.

Please let me know how to effectively modify nova.conf so that the

[Openstack] Swift replication analysis and questions (high CPU usage)

[Julien Danjou]

Hi there,

We're currently running a 3 nodes installation of Swift. We saw that the
CPU usage on this nodes is always very high, around 50%, with no users
connected, and we'd like to be sure there's not something wrong.

So I did some analysis and the whole point of this mail is to be
corroborated or invalidated.

Facts
=
These 3 nodes are hosting account, containers and objects.

The following processes take a lot of CPU time:

  swift-container-replicator
  swift-container-server
  swift-object-replicator
  swift-object-server

The object replication time as indicated in log and by swift-recon
showed that it took around 5 minutes.
The options used are the default ones (nothing fancy then).
We replicate each account/container/objects 3 times.

Volumetry:
- 450 GB of storage used (each node has 19 TB)
- 57 accounts
- 7929 containers in 7870 partitions
- 58158 objects partitions used so far

Each ring has been built with 2^18 (262144) partitions.

The containers and objects sync run at around 300 partitions/s.

Analysis

What's taking CPU time is replication. If I understand correctly, the
container and object replicators walks through their respective
directories, and send a REPLICATE command to all the other servers
responsible for the same partition. Since there's only 3 servers for 3
replicates, obviously all nodes hold all the partitions. That means that
swift-{objecter,container}-replicator processes of host A will send
REPLICATE requests to hosts B and C, making the
swift-{object,container}-server process uses CPU on host B and C to
return some response indicating that the data must be rsync-ed or not.

For containers, it means that it walks ~8K directories and open 8K
sqlite database, send 2 REPLICATES, and does nothing (when everything is
in sync, which is the case 99.999% of the time).
For objects, it means that it walks ~58K directories and open the
hashfile for each of its 58K partitions and send 2 REPLICATES, and does
nothing (when everything is in sync, which is the case 99.999% of the
time)

For containers, it does that every 30s (by default). With around 8K
containers, it takes more than 35s, so swift-container-replicator uses
one CPU at 100 % all the time.
For objects, it does that in 5 minutes and pauses for 30s (by default).


If this is the normal behaviour, I can then conclude that:
- we need more hosts to lower CPU usage, because when we'll reach the
  262K objects partitions used, the CPU usage will explode and the
  objects synchronisation time will increase by 5 times.
  For example adding 2 more hosts would allow to reduce by 40 % the
  number of partitions hosted on each hosts (each would have 60 % of
  partition space rather than 100 %).

- we should have used less partitions to use on such a small hosts,
  probably something between 2^10 and 2^14 (we'll add more hosts, but
  probably not thousands).


What I did so far is to increase the number of workers and the
concurrency setting. Setting concurrency to 32 (each hosts has 8 CPU
cores) for object replicator pushed the CPU usage to 80 % (reminder:
50 % before) but divided the replication time by more than 2 (~2 minutes
instead of 5 minutes).

This doesn't help with CPU usage obviously, it's worst, but at least it
takes just 30 % more CPU to do the same thing twice in the same time
frame.

Thanks for any hint or helpful comment about this!

Hi,


In dashboard, in the images/snapshots area can you list the images ?
Can you put the output of glance-api, please ?

[Openstack] nova.conf query

[Salman Malik]

Hi All,

A quick question regarding nova.conf: How can I modify nova.conf and get it to 
work with devstack. The problem that I am facing is after modifying nova.conf, 
I have to reboot so as to restart services. But when I reboot, devstack needs 
to be reinstalled all over again using stack.sh and in the process it rewrites 
/etc/nova/nova.conf. 

Also according to documentation we can set flags in nova.conf using 
--= format. Is that an obsolete format ? (because the 
nova.conf that devstack creates don't have any -- in it). 

Please let me know how to effectively modify nova.conf so that the changes take 
effect (I am looking forward to change the network manager...)

Thanks!

Salman

Re: [Openstack] Open Cloud Computing Interface Blueprint Implementation

[alexander.papaspyrou]

Hey Andy,

this is excellent news! Thanks for the effort you took to close this gap and 
make it finally happen!

I am delighted to see that we will finally have the opportunity to build our 
OCCI clouds using OpenStack. Especially in my day job as a researcher, I am 
constantly approached by the projects I am involved in which OCCI 
implementation to use for infrastructure management, and many of them already 
run OS as their platform. It will be great to see those being now able to 
integrate with other partner institutions via the OCCI interface without having 
to move away from CS.

Keep up with it, and thanks for the great work!
 
 Best,
Alexander

One item more into HA features, hot plugging.

be shutoff,
  and the remote entry would be given time to ack that.

Re: [Openstack] I18n issue for OpenStack

The exception is used for flow control when it happens. yes, that's right
but not completed.:-)
When you look into the current design of exceptions such as nova
exceptions, they include message content which is meaningful and useful.
Apparently, the exception is not only used for flow control, but also for
showing user why this could happen. It is not bad smell for code or
conflict with MVC design pattern, I think. Add another separate layer is
complex and not necessary. The gettext tookit allow the message to be
translated or untranslated. It depends on the user requirements on this
that we can't ignore.

nova/nova/exception.py:
...
class DecryptionFailure(NovaException):
message = _("Failed to decrypt text")


class ImagePaginationFailed(NovaException):
message = _("Failed to paginate through images from image service")


class VirtualInterfaceCreateException(NovaException):
message = _("Virtual Interface creation failed")


class VirtualInterfaceMacAddressException(NovaException):
message = _("5 attempts to create virtual interface"
"with unique mac address failed")

message = _("Connection to glance failed") + ": %(reason)s"

So u have just touched on another issue,

I would still say that exception messages should not be translated (+1),
haha.

If this is needed, then there is something wrong with the code and how
exceptions are used instead (ie the bad code smell). Exceptions should be
meant for error control flow, what they were designed for, not for user
facing messages. I think it is more common to have a layer that translates
exceptions into meaningful localized messages, but there needs to be a
separation between exceptions and there localized messages (they should not
be combined). This is a common thing afaik, its called separation of model
and view, aka, mvc, (think of the exceptions as a model/controller(?), if
the messages �C the view are intertwined that seems broke).

This is common with a lot of other parts of openstack as well, ec2
formatting/response creation should be separated from nova logic (ec2
should be a view, which it mostly 

Re: [Openstack] Open Cloud Computing Interface Blueprint Implementation

[Matteo Turilli]

Hi Andy,

Great Work! At the EGI FedCloud Task Force [1] we chose OCCI for the 
federation so a native OCCI interface for OpenStack is very welcome.


Thanks to the availability of OCCI implementations, our user communities 
can instantiate VMs through a single type of interface on resource 
providers running OpenStack, OpenNebula, WNoDeS and so on.


Many thanks,
Matteo

That's interesting! We'd love to run rsync on top of swift, but our
experience so far is quote discouraging.

We maintain a SFTP proxy to swift:

https://github.com/Memset/sftpcloudfs

And there's Chmouel FTP proxy too:

https://github.com/chmouel/ftp-cloudfs

As SFTP/FTP are "file transfer" protocols, not having a real filesystem
underneath it's not that important.

Juan

Hello,

If it helps, that's the way we're accounting and managing quotas in our
swift deployment (Memstore).

We use a background process in each proxy server that runs through the
logs to account source IP, bytes in, bytes out and requests per account,
and another background process to account bytes, container and object
count using swift API.

We have a small middleware in the proxy that limits HTTP operations.

For example, if the disk is over quota we forbid PUT requests for that
account (GET, DELETE are still valid).

We have found quotas are little bit difficult to enforce though. Being
accurate has an important performance hit, so our quotas are
"eventually" enforced (blame memcache for that), and by now is close
enough for us.

Regards,

Juan

Re: [Openstack] Open Cloud Computing Interface Blueprint Implementation

[jean-pierre laisne]

Hey Andy,

Great job. We will add it to the list of
CompatibleOne Procci
ASAP. Having a 100% OCCI compliant interface will greatly help all kind of
developments targeting cloud services interoperability, federation, broker,
etc.
Plus it makes OpenStack a pure open cloud player (i.e. open cloud = open
source + open standards) as an alternative to all closed ones.

Best wishes,
CompatibleOne team

Re: [Openstack] Open Cloud Computing Interface Blueprint Implementation

[GHRAB, Amine]

Hello Andy,

Thanks for the good news.

We are using OCCI to manage multiple clouds through a unique
interface.
Having OpenNebula OCCI Server already implemented [1]  and EC2 on its
way, I think a big step is achieved with the OpenStack OCCI
implementation to provide a way to manage seamlessly multiple cloud
providers  through a unique interface. 

Breaking cloud providers lock-in seems no longer a distant dream :)

Good to hear, I'm looking forward hearing more of you project. It
sounds like it would be plug-in to the earlier mentioned project:

http://wiki.openstack.org/ResourceMonitorAlertsandNotifications

You are right, one cannot have too many "heads" making the decisions
about HA in the cluster, Nova should handle it, or let someone else to
do it and let go. But isn't that exactly what nova is there for, so
it's nova's job.

BR,

I had such"cant connect to 169.254.169.254) on some compute-node where
nova-api was not running:

http://docs.openstack.org/cactus/openstack-compute/admin/content/configuring-multiple-compute-nodes.html

Note sure it apply on your case as you mention devstack (so i am

nova-api is actually running.

Thanks for the links, I'll look into them. It looks good having a
pluggable monitoring interface. By a quick look I don't see how do the
local driver connect to libvirt, is the alert notified in fast manner
or based on periodic polling. I need to take a further look into it.

Hopefully there could be local HW watchdog emulated in Qemu that would
somehow be connected to the plugin framework to allow fast reaction
times to guest being stuck.

Also, it would make sense to have some kind of a local decision done
immediately about the reboot of a stuck  guest, instead of taking time
to report it centrally and wait for the central manager decision.

cheers,
Ilkka
