[Openstack] I18n issue for OpenStack
Hi there from OpenStack Community,
After the research done by my colleage Edward Zhang and myself, we have
found the following issues for openstack. We have already raised bug
https://bugs.launchpad.net/nova/+bug/974810.
1. The ROOT cause that i18n did not work in Nova
In Nova, within nova.image, there is a python file glance.py. This file
has a line of code GlanceClient =
utils.import_class('glance.client.Client'),
which calls the class glance.client.Client from Glance project. Each time
this line of code is called, the gettext domain will change from nova to
glance. But it doesn't recover nova domain after glance client returns the
control. So the i18n won't be correctly working in nova.
Detailed explanation:
Within Nova.__init__.py, there is gettext.install('nova', unicode=1). If
we want to make i18n (e.g. Chinese) work,
we need to modify it into gettext.install('nova', [path of locale
directory], unicode=1). The first parameter nova is the domain for i18n
within nova project.
However, when the code as the right image shows is called,
gettext.install('glance', unicode=1) within glance.__init__.py will be
called. So the domain switches
from 'nova' to 'glance', though we are still running the nova project.
Nova project needs 'nova' as the domain. When the domain changes,
certainly i18n will fail.
2. Differences between the development mode and the operation mode
We are using devstack to run our environment. As we talked about changing
gettext.install('nova', unicode=1) into
gettext.install('nova', [path of locale directory], unicode=1) before,
this may lead to another issue. gettext.install has a default directory,
which is where openstack
can install its locale files, like all the .mo files. However, devstack
does not install locale files in the default directory, which is why we
need to make the change.
We suggest that openstack have two modes: development and operation.
Different modes have different settings for the paths.
3. Improvement of the context management
There is blueprint about decoupling client code of glance from the glance
project and there is a python-glaceclient under development. It can
resolve i18n issue potentially, since
nova won't call glance directly and glance domain won't be loaded in nova.
In our opinion, we would call it AVOID it rather than RESOLVE it. If we go
one step further,
this indicates that there is an issue for the context management.
OpenStack has different projects and different logging environments, etc,
which we call context.
It is natual for us to switch context b/w different program, e.g. from
nova to glance. In nova, there is no clear management and indication that
the context
has been changed or clear exist for the context to switch back. The i18n
issue is just a tip of the iceberg for the context management. It is a
potential improvement for openstack.
We hope the above information can help OpenStack become better and we
would like to hear more comments from our community.
Thank you very much.
Best wishes.

Hi,
I have setup two Compute nodes (using Openstack master branch) and configured
libvirt for block migration (by following step #1 and #4 mentioned
herehttp://docs.openstack.org/diablo/openstack-compute/admin/content/configuring-live-migrations.html).
In addition, I have also disabled apparmor for libvirtd profile and have an
entry in '/etc/hosts' of both the Compute hosts.
From both the Compute hosts, I am able to connect and fetch the list of
running instances on the other host (using the hostname), as follows:
virsh # connect qemu+tcp://ubuntu-dev-001/system
virsh # list
The issue is block migrating an instance between these hosts fails with the

I’m all for open dialogues. In fact. I was thinking of what is needed to make this work better. Open questions/thoughts/brainstorm (at least that I was thinking of): How strict do we want to be with the XSD? (there aren’t a lot of tolerant xsd validators out there, which sux) Should we use something like jaxb for python, that should be more tolerant (unsure as what the best solution here is) How do we continuously measure the compatibility level? # of test cases passing, # of xml differences, # of xsd issues Should we use boto as a intermediate layer? (it is very tolerant) From what I understand there XML code is basically selecting certain attributes out of the XML using SAX, then adding any unknown attributes dynamically on to a object How do we make it repeatable? For a given test X, if there is a problem with test X and its response Y, how do we easily recreate that test X and response Y (so that dev’s can fix it)? Do we have a “golden set” of responses that when test X is called it should match golden response Z (otherwise there is an issue) This is where the mock server maybe useful, in that we can point test X at the mock server; get the expected responses Z, Then point the test X at the real openstack server and get responses Y that should match Z (exactly, minus the request id?) EC2 seems to also already have some type of mocking, but I haven’t used it... (http://bit.ly/HJkdh7) I like how there is a tests folder that u guys have, that seems like it could be a good location for the “content checking tests” which actually require code/logic to dig into the XML response. It might make sense to use another tool to verify the XSD’s (how tolerant we want to be is an open question) and another tool that will show u the xml differences (some of which might be ok, some not). I have used in java xmlunit to do those kind of xml difference comparisons, it provides some nifty ways of ignoring certain differences and such. If say we had 3 levels of tests I think that would make sense (starting say from XSD validation, to difference comparisons to content comparisons), and would make a hell of a EC2 cool validation toolkit. The other usage of the site I was making was to list all the known error conditions, and any other incompatibilities that I am noticing with EC2 (error conditions, features, parameters...). That seems really needed to allow for anyone to actually use the EC2 apis and handle all the cases which could be thrown at them. -Josh On 4/10/12 7:02 PM, Eric Windisch e...@cloudscaling.com wrote: Josh, as a follow-up, it would be good to keep an open dialogue on this.

Re: [Openstack] question about keystone and dashboard on RHEL6
Diablo (at least for nova, glance, swift) is capable of using keystone there is however a lot of manual configuration needed, something that is on my list for complete when integrating keystone into my 2011.3 deploy per my blog post. All I can say at the moment is this is far from trivial, and finding documentation on this can be a problem (if anyone on the list could correct me on this, it would help massively and expidite my documentation of integrating keystone with nova glance on 2011.3) Cheers Davud On Wed, Apr 11, 2012 at 4:16 PM, Adam Young ayo...@redhat.com wrote: On 04/03/2012 09:25 AM, Russell Bryant wrote: On 04/02/2012 08:44 PM, Xin Zhao wrote: On 4/2/2012 6:35 PM, Russell Bryant wrote: On 04/02/2012 03:09 PM, Xin Zhao wrote: Hello, I am new to OpenStack and trying to install the diablo release on a RHEL6 cluster.

Re: [Openstack] [openstack][keystone] Service isolation?
On 04/10/2012 09:44 PM, Nguyen, Liem Manh wrote: Hi fellow Stackers, I am reading http://keystone.openstack.org/configuringservices.html, and it appears that for service registration, all services (or rather service users) reside within the same tenant with the same Admin role. So, if I understand it correctly, it is then possible that a service user for Nova can actually accidentally nuke an endpoint for a Glance service, for example? Don't we want isolation among services, i.e., a user owning one service may not modify another service that he/she did not create? Hi Liem! As Joe Heck noted, the concept of roles hasn't changed from the Diablo codebase, and there is certainly the danger of a service tenant user nuking an endpoint for a different service, as you describe above. In Glance, we added a config option admin_role that can be set to guard against this, however. Just set admin_role = glance_admin and create a glance_admin role in Keystone and just assign the Glance service user (and only that user) that role... Kind of a hacky workaround, but it works...

I'm all for open dialogues. In fact. I was thinking of what is needed to make this work better. Open questions/thoughts/brainstorm (at least that I was thinking of): How strict do we want to be with the XSD? (there aren't a lot of tolerant xsd validators out there, which sux) Should we use something like jaxb for python, that should be more tolerant (unsure as what the best solution here is) How do we continuously measure the compatibility level? # of test cases passing, # of xml differences, # of xsd issues Should we use boto as a intermediate layer? (it is very tolerant) From what I understand there XML code is basically selecting certain attributes out of the XML using SAX, then adding any unknown attributes dynamically on to a object How do we make it repeatable? For a given test X, if there is a problem with test X and its response Y, how do we easily recreate that test X and response Y (so that dev's can fix it)? Do we have a golden set of responses that when test X is called it should match golden response Z (otherwise there is an issue) This is where the mock server maybe useful, in that we can point test X at the mock server; get the expected responses Z, Then point the test X at the real openstack server and get responses Y that should match Z (exactly, minus the request id?) EC2 seems to also already have some type of mocking, but I haven't used it... (http://bit.ly/HJkdh7) I like how there is a tests folder that u guys have, that seems like it could be a good location for the content checking tests which actually require code/logic to dig into the XML response. It might make sense to use another tool to verify the XSD's (how tolerant we want to be is an open question) and another tool that will show u the xml differences (some of which might be ok, some not). I have used in java xmlunit to do those kind of xml difference comparisons, it provides some nifty ways of ignoring certain differences and such. If say we had 3 levels of tests I think that would make sense (starting say from XSD validation, to difference comparisons to content comparisons), and would make a hell of a EC2 cool validation toolkit. The other usage of the site I was making was to list all the known error conditions, and any other incompatibilities that I am noticing with EC2 (error conditions, features, parameters...). That seems really needed to allow for anyone to actually use the EC2 apis and handle all the cases which could be thrown at them. -Josh On 4/10/12 7:02 PM, Eric Windisch e...@cloudscaling.com wrote: Josh, as a follow-up, it would be good to keep an open dialogue on this.

We plan to discuss how to fix and extend I18N at the summit. One question that was raised on the ML in February was whether internationalization was actually worth the effort for infrastructure software like OpenStack. I'll be the first to admit that there are other languages than English, but all our open development is based in English already (bugs, reviews, commit messages, mailing-lists, IRC...), so I don't think supporting more languages in the software itself will help growing our developer community. I would tend to disagree with that. People are more likely to invest their time in software if they'll be able to use it better in their locale. I think this is definitely even more true in places where English has less of a dominant presence. It may even bring people to the table solely interested in helping with translation. I've seen that happen elsewhere. On our users community, do operators of OpenStack need translated error messages ? Given that translations are often incomplete, is it worth it ? What do comparable infrastructure open source software projects provide ? The effort to provide them has proven non-trivial, I'd like to make sure it's time well spent. If we want to think about OpenStack as a basic building block like Apache, i18n is critical. Otherwise there are regions that won't adopt it solely because of a lack of i18n. Is there a metric on the completeness so far?

Based on that we can determine if there is a group interested in continuing to own maintenance for an additional period. It's a good question, and one that we still need to figure out an answer to. Judging by the level of interest so far in helping to maintain the branch, I think this would work: - Core projects in a given release have a stable branch for that release maintained by openstack-stable-maint - A stable branch is actively maintained (read - the branch maintainers actively monitor master for patches to backport and release new versions from the branch) until the next release comes out - A stable branch is then passively maintained (read - the branch maintainers will backport security fixes and accept patches for high impact issues, but will not do new releases) until the next release after that comes out Giving a current state of stable-maint actively maintaining stable/essex and passively maintaining stable/diablo. We will EOL stable/diablo when Folsom comes out. Of course, we can always re-evaluate the policy if interest increases. Looking forward to discussing further at the summit ... Thanks Mark.

[Openstack] profiling nova-api
Hi Stackers, I spent some time looking at nova-api today.
Setup: everything-on-one-node devstack, essex trunk. I setup 1 user
with 10 tiny VMs.
Client: 3 python threads each doing a loop of nova list equivalent
for 100 times. So 300 API calls with concurrency=3.
how to profile: python -m cProfile -s time
/opt/stack/nova/bin/nova-api --flagfile=/etc/nova/nova.conf
--logdir=/var/log/nova --nodebug
The partial output is attached in the end.
Observations:
* It takes about 60 seconds to finish. CPU of nova-api is around 70% to 90%
* Database access: Each nova list API call will issue 4 db APIs: 3
instance_get_all_by_filters(), 1
instance_fault_get_by_instance_uuids(), so 1200 db API calls total
(note: not necessarily 1200 SQL statements, could be more). The 900
instance_get_all_by_filters() calls took 30.2 seconds (i.e. 0.03s
each)! The 300 instance_fault_get_by_instance_uuids() calls only took
1.129 seconds (0.004 each).
You might think: MySQL sucks. Not so fast. Remember this is a tiny
database with only 10 VMs. Profile also shows that the actual
_mysql.connection.query() method only took 1.883 seconds in total. So,
we pretty much spend 29 seconds out of 60 seconds doing either
sqlalchemy stuff or our own wrapper. You can also see from the sheer
volume of sqlalchemy library calls involved.
* the cfg.py library inefficiency. During 300 API calls,
common.cfg.ConfigOpts._get() is called 135005 times! and we paid 2.470
sec for that.
Hopefully this is useful for whoever wants to improve the performance
of nova-api.
Thanks,
Yun

A few notes: a) managing one administrative api across multiple projects is going to be difficult, might be good to focus on each project individually, perhaps pushing some common code into openstack-common. b) users/projects/roles is out of scope for nova, this can be administered through keystone + keystone-client c) a lot of administrative features are already in the nova cli (you can delete networks but not create them yet) I think there will be some serious weight behind the operational support team in this cycle.

The Keystone repo currently contains the following Swift-specific wsgi middleware modules: https://github.com/openstack/keystone/blob/master/keystone/middleware/s3_token.py https://github.com/openstack/keystone/blob/master/keystone/middleware/swift_auth.py Neither module depends directly on Keystone. s3_token calls Keystone through HTTP, and swift_auth retrieves Keystone identity data from the wsgi environment. Both modules, however, depend directly on Swift, and this forces the Keystone test suite to have to install Swift to run successfully. Separate from the dependency issue, both middleware modules need to ensure that Swift-specific authorization requirements are met. It doesn't make sense for the Keystone project to be responsible for this, since the Swift team is the final arbiter of how Swift authorization should behave. All signs point to the Swift repo being the best place for these modules to be maintained. Does this seem reasonable, or is there a better alternative? Please chime in, especially if you are Swift core.

When I led tracks at Ubuntu Developer Summits, we were able to keep remote attendees closely in the loop. As non-optimal as this may be, we can still work hard to get the best out of it. I'm not sure it the Design Summit will be projecting IRC chat on a screen for each session (like is done at UDS); at the very least, I can make sure I'm on Freenode and can act as a proxy -- ensuring any questions or concerns from IRC get audibly voiced and become part of the conversation.

Re: [Openstack] profiling nova-api
Awesome, great stuff to know!
On 4/11/12 1:48 PM, Yun Mao yun...@gmail.com wrote:
Hi Stackers, I spent some time looking at nova-api today.
Setup: everything-on-one-node devstack, essex trunk. I setup 1 user
with 10 tiny VMs.
Client: 3 python threads each doing a loop of nova list equivalent
for 100 times. So 300 API calls with concurrency=3.
how to profile: python -m cProfile -s time
/opt/stack/nova/bin/nova-api --flagfile=/etc/nova/nova.conf
--logdir=/var/log/nova --nodebug
The partial output is attached in the end.
Observations:
* It takes about 60 seconds to finish. CPU of nova-api is around 70% to 90%
* Database access: Each nova list API call will issue 4 db APIs: 3
instance_get_all_by_filters(), 1
instance_fault_get_by_instance_uuids(), so 1200 db API calls total
(note: not necessarily 1200 SQL statements, could be more). The 900
instance_get_all_by_filters() calls took 30.2 seconds (i.e. 0.03s
each)! The 300 instance_fault_get_by_instance_uuids() calls only took
1.129 seconds (0.004 each).
You might think: MySQL sucks. Not so fast. Remember this is a tiny
database with only 10 VMs. Profile also shows that the actual
_mysql.connection.query() method only took 1.883 seconds in total. So,
we pretty much spend 29 seconds out of 60 seconds doing either
sqlalchemy stuff or our own wrapper. You can also see from the sheer
volume of sqlalchemy library calls involved.
* the cfg.py library inefficiency. During 300 API calls,
common.cfg.ConfigOpts._get() is called 135005 times! and we paid 2.470
sec for that.
Hopefully this is useful for whoever wants to improve the performance
of nova-api.
Thanks,
Yun

Re: [Openstack] Where does Keystone middleware for Swift belong?
Agreed that s3_token belongs in Swift, and as per Joshua, ec2_token probably belongs in Nova.

[Openstack] [DESIGN SUMMIT] Short training video for session leaders and participants to the summit
Hello all, we want to have the most productive time during the next week. We'll have many sessions to attend to, decision to make, things to learn and also have fun. Last time we had a summit some people asked us to improve how the tracks are managed during the summit. Jim Plamondon kindly volunteered to give some pointers for session leaders and participants to the OpenStack Folsom Design Summit. Please watch this video, it's brief and will help you make the most of your time next week: https://www.youtube.com/watch?v=GmY4cK_6NKY If you know somebody that should watch it too, pass it along, tweet it: spread the word.

Re: [Openstack] Instance can't reach dhcp or metadata
Dan, Bug you referred to specifically says default tenant - which is not the case for me. I'm not using default tenant - I'm using uuid of demo tenant created by stack.sh BTW, stack.sh creates incorrect entries in quantum/mélange DB, it has tenant ID = default - This should be uuid of some valid tenant, not string default FWIW, this setup (although seems incorrect) works with quantum+nova_ipam - not with quantum+mélange i.e. With quantum+nova_ipam I can just create a VM and ssh to it. -Mandar From: Dan Wendlandt [mailto:d...@nicira.com] Sent: Wednesday, April 11, 2012 11:07 PM To: Vaze, Mandar Cc: Nicolas de BONFILS; openstack@lists.launchpad.net Subject: Re: [Openstack] Instance can't reach dhcp or metadata On Wed, Apr 11, 2012 at 5:24 AM, Vaze, Mandar mandar.v...@nttdata.commailto:mandar.v...@nttdata.com wrote: I have never been able to get to ssh to an instance with Quantum+mélange https://lists.launchpad.net/openstack/msg09206.html Looking at that thread, I suspect you may be hitting the same issue I mentioned above: https://bugs.launchpad.net/quantum/+bug/949234 If you try that fix and either do or don't have luck with it, please add a comment to the issue.

[Openstack-poc] [Bug 972859] Re: Fix utils.import_object() when trying to get an instance of a class
Reviewed: https://review.openstack.org/6191

commit 4acd7829ab0857356594dce3b841f4d785cf2aa1

Change behavior in utils.import_object().
Fix bug 972859.
Prior to this patch, utils.import_object(foo) and
utils.import_class(foo) would return the same thing if foo was the path
to a class. This patch changes utils.import_object() to return an
instance of the class, instead, also allowing you to pass in arguments
to the constructor.
This patch also removes the odd behavior of import_object() to be able
to also import a module. Instead, a new function import_module() has
been added.
Finally, the three import helpers have been moved to a new module,
importutils.

Fix utils.import_object() when trying to get an instance of a class
Status in openstack-common:
Fix Committed
Bug description:
RIght now, utils.import_object('foo') is the same as
utils.import_class('foo') when 'foo' is the path to a class. This
should be fixed so that import_object() returns an instance of that
class (like how this works in nova.utils).
