This is expected. Look for it under /home/ec2-user instead. Of course, if it isn't there either then there may be a problem. ;-)

OpenStack devstack on Fedora
by Russell Bryant 22 Mar '12

22 Mar '12

Greetings, If you've done any work with upstream OpenStack, you have almost certainly come across devstack (devstack.org) Fedora support is now being added to devstack. I created a wiki page to start documenting the use of devstack on Fedora. Give it a try and update with any helpful tips you come across: https://fedoraproject.org/wiki/OpenStack_devstack Thanks, -- Russell Bryant

OpenStack Summit/Conf. & Marketing Collateral (a two-part email!)
by Robyn Bergeron 21 Mar '12

21 Mar '12

Howdy howdy Cloud SIG pals, This is a dual-purpose email, so if you don't care about the first part (OpenStack Summit/Conf.) at least bear with me and skip on to the second part :) First: There is a handful of folks from Fedora-land, I suspect, who will be in attendance at the OpenStack Summit & Conference coming up April 16-20. I've arranged for us to have some shared .org booth space at the event; we would likely want to staff that on Thursday/Friday (the conference portion), though my understanding is that the booth area will likely be open all days of the week. I'll be in attendance, but would love to have some backup. I'm not asking for anyone to spend all day, but if you can spend an hour or two over a day or two, that would be rockin'. I've made an event page to try and organize anything we have going on at the event, here: https://fedoraproject.org/wiki/OpenStackSummitConf_April2012 So if you're planning on attending, and are willing to hang at the booth at some point, please add your name to the "Fedora Representatives" section, and as soon as the schedule looks more firm (or published, really) we can try and nail down a more firm schedule for boothiness. And I also won't have to subject everyone on the Cloud SIG mailing list to reading the hashing out of schedule details. :) Also: I'm curious if anyone might be interested in wrangling some sort of Fedora/OpenStack BoF, maybe Thursday night, or $someothertime? I think it would be a good way to connect with people who might be potential contributor types, might be willing to test, etc. I'm planning on having a small amount of media and some stickers to give away at the booth, but I think it would be SUPER BENEFICIAL to have some Cloud-specific collateral to give away, since the audience for this is obviously very targeted. AND THUS BEGINS THE SECOND PART OF THE MAIL. More generally, I think it would be great to have some Cloud SIG materials available for conferences and such, not just this one. I've created some *incredibly* drafty brainstorming pages for two pieces of material that we could do as flyers, or nicer-printed-on-heavy-paper-special-sized handouts: * Cloud SIG or Fedora in the Cloud: https://fedoraproject.org/wiki/Cloud_Marketing_Collateral/Cloud_SIG I'm thinking this would be more of a catch-all, "What is in Fedora that is cloudy" handout, including EC2 info as well as some of the tooling we have. * OpenStack & Fedora: https://fedoraproject.org/wiki/Cloud_Marketing_Collateral/OpenStack_in_Fedo… For this: I'm thinking "What's in F16, What's coming in F17", as well as more generalized info ("About Fedora," "Contributing to the Cloud SIG"). So in a nutshell: If you're one of the folks working on the OpenStack stuff, I would muchomucho appreciate your help/content/etc. in creating this second flyer; if you're Anyone who Cares about Fedora and Cloud, I would love your help in creating content for the first flyer listed. Additionally, I've requested a logo for our lovely group from the Design Team, so hopefully they can come up with something awesome. Once we have a good handle on content for flyers, we can probably work with the design team to come up with something that actually looks nice in addition to being informative. Obviously, other flyer ideas are welcome too, the OpenStack one is mostly to have something specific for a very narrowly-focused event. Your feedback is welcome, as always. :D -Robyn

OpenStack status
by Mark McLoughlin 20 Mar '12

20 Mar '12

Hey, Here's our latest update: http://fedoraproject.org/wiki/OpenStack_status_report_2012-03-20 Thanks to Pádraig for his help pulling this one together. Hopefully, with Pádraig's help, these updates will become much more regular :) We've decided to push these to the wiki instead of just by email. Historical archives are here: http://fedoraproject.org/wiki/OpenStack_status_reports Cheers, Mark. (appended below for convenience) OpenStack status report 2012 03 20 = Test Day = We held a [[Test_Day:2012-03-08_OpenStack_Test_Day|test day for OpenStack Essex in Fedora 17 on March 8]]. The event was fairly well attended with 11 people reporting their test results on the wiki page. The set of test cases we used were heavily based on the [[Test_Day:2011-10-20_OpenStack_Test_Day|Fedora 16 Test Day]] but included testing Keystone, Horizon and Quantum (with openvswitch) integration. We also had instructions detailing how to run the Tempest test suite. Finally, for the first time, we had a Fedora 16 guest image that everyone could download and use for testing. Running through the various tests highlighted some of the implications of using keystone authentication e.g. # <code>nova-manage</code>'s user and project commands become obsolete # Equivalent of <code>nova-manage project zipfile</code> is non-trivial # <code>nova-manage image convert</code> doesn't work anymore, you need to use glance directly Worryingly, we hit a number of serious SELinux issues e.g. # [https://bugzilla.redhat.com/801299 #801299 - AVC when first starting mysqld] # [https://bugzilla.redhat.com/801330 #801330 - AVC denials starting OpenStack glance services] # [https://bugzilla.redhat.com/801352 #801352 - SELinux policy for OpenStack's new nova-cert service] # [https://bugzilla.redhat.com/801746 #801746 - SELinux AVC denial executing from /tmp] # [https://bugzilla.redhat.com/760055 #760055 - SELinux policy for keystone] Horizon mostly "just worked", which is really great. We did file a number of bugs, though: # [https://bugzilla.redhat.com/801745 #801745 - intermittent database connection errors] # [https://bugzilla.redhat.com/801690 #801690 - horizon: download ec2 credentials fails] # [https://bugzilla.redhat.com/801688 #801688 - horizon: cannot delete a user or project] # [https://bugzilla.redhat.com/801686 #801686 - horizon: failed to detach or delete a volume] # [https://bugzilla.redhat.com/801685 #801685 - horizon: no VNC console] # [https://bugzilla.redhat.com/801684 #801684 - horizon: action dropdowns don't appear to work] # [https://bugzilla.redhat.com/801208 #801208 - tenant chooser doesn't work] Some other bugs filed include: # [https://bugzilla.redhat.com/803354 #803354 - keystone returns 500 errors after a while] # [https://bugzilla.redhat.com/801452 #801452 - euca-describe-instances does not show IP addresses] # [https://bugzilla.redhat.com/801312 #801312 - webob deprecation warnings] # [https://bugzilla.redhat.com/801302 #801302 - sqlalchemy-migrate warnings during openstack-nova-db-setup] # [https://bugzilla.redhat.com/801366 #801366 - [API] Invalid X-Auth-Token breaks API service] # [https://bugzilla.redhat.com/800704 #800704 - keystone endpoint-list tracebacks] We also stumbled across this cheeky little libvirt regression introduced by switching to systemd: # [https://bugzilla.redhat.com/802475 #802475 - libvirt in a VM occasionally brings up 'default' network when it shouldn't, kills vm networking] One idea for future improvement is for us to use a dedicated yum repository for the test day to remove any ambiguity about which updates have been pushed to the mirrors and to allow us to quickly push out fixes on the day itself. = Fedora 17 = == Essex Release Progress == The [https://lists.launchpad.net/openstack/msg08173.html essex-4 milestone] was released on March 1 and quickly pushed into Fedora 17, as was [https://lists.launchpad.net/openstack/msg08445.html swift 1.4.7] and [https://lists.launchpad.net/openstack/msg08197.html Quantum essex-4]. The Essex release now enters its release candidates phase in the lead up to the final release on April 5. So far, [https://lists.launchpad.net/openstack/msg08855.html Nova rc1] and [https://lists.launchpad.net/openstack/msg08806.html Quantum rc1] have been released, and Swift has tagged its [https://launchpad.net/swift/+milestone/1.4.8 1.4.8 release]. == Getting Started Wiki == In preparation for the Fedora 17 release, we have updated the [[Getting_started_with_OpenStack_Nova]] wiki page and moved it to [[Getting_started_with_OpenStack_on_Fedora_17]]. The new instructions include details on how to use Keystone authentication and the Horizon dashboard. Also [[Quantum]] installation and troubleshooting steps have been prepared for testing nova and quantum in a multi-node setup using openvswitch as a plugin. == F-17 Package Updates == Since the last status report, the following notable updates have been pushed to F-17: * [http://admin.fedoraproject.org/updates/openstack-nova-2012.1-0.7.e4.fc17 openstack-nova-2012.1-0.7.e4.fc17] *# update to essex-4 *# switch to new <code>.ini</code> style conf file format *# depend on [https://bugzilla.redhat.com/788485 new bridge-utils package] * [http://admin.fedoraproject.org/updates/openstack-nova-2012.1-0.8.e4.fc17 openstack-nova-2012.1-0.8.e4.fc17] *# support non-blocking libvirt operations *# suppress power state errors *# fix [https://bugzilla.redhat.com/801791 nova-compute failing to start] *# fix [https://bugzilla.redhat.com/801302 sqlalchemy-migrate warnings during openstack-nova-db-setup] *# fix [https://bugzilla.redhat.com/803905 osapi v1.1 returns errors when getting server status] * [http://admin.fedoraproject.org/updates/openstack-glance-2012.1-0.5.e4.fc17 openstack-glance-2012.1-0.5.e4.fc17] *# Update to essex-4 *# Require pyxattr rather than python-xattr *# Add python-iso8601 dependency * [http://admin.fedoraproject.org/updates/openstack-keystone-2012.1-0.9.e4.fc17 openstack-keystone-2012.1-0.9.e4.fc17] *# Update to essex-4 * [http://admin.fedoraproject.org/updates/openstack-keystone-2012.1-0.10.e4.fc… openstack-keystone-2012.1-0.10.e4.fc17] *# [http://bugzilla.redhat.com/800704 Change default catalog backend to sql] *# Add missing keystoneclient dep *# Add openstack-config-set script * [http://admin.fedoraproject.org/updates/python-django-horizon-2012.1-0.1.rc1… python-django-horizon-2012.1-0.1.rc1.fc17] *# Update to RC1 snapshot *# Change default URL to <code>http://localhost/dashboard</code> *# Fix [https://bugzilla.redhat.com/788567 static content] * [http://admin.fedoraproject.org/updates/openstack-quantum-2012.1-0.3.e4.fc17 openstack-quantum-2012.1-0.3.e4.fc17] *# Depend on Open vSwitch * [http://admin.fedoraproject.org/updates/openstack-quantum-2012.1-0.5.e4.fc17 openstack-quantum-2012.1-0.3.e5.fc17] *# Update to Essex RC1 candidate tarball == Open vSwitch Package Review == Chris Wight and Dan Berrange worked [https://bugzilla.redhat.com/799171 openvswitch through the review process]. [[Features/Open_vSwitch|Open vSwitch]] is a major Fedora 17 feature that is going to be hugely beneficial to OpenStack and Quantum in Fedora. Very exciting! == Multiple Instances of Swift Services == When swift moved from SysV init to systemd, we lost the ability to launch multiple instances of the same service on a machine. Derek stumbled across systemd's "instances" support and we'll soon re-instate this support. See [https://bugzilla.redhat.com/805149 #805149] for more details. == Keystone LDAP Support == Adam Young had his [https://review.openstack.org/4362 LDAP backend] merged into keystone for essex-4. Adam blogged about [http://adam.younglogic.com/2012/02/freeipa-keystone-ldap/ using keystone's LDAP driver with FreeIPA]. = Misc Fedora News = == F-16 Guest Images == Dan Berrange [http://www.spinics.net/linux/fedora/fedora-cloud/msg01304.html posted a F-16 guest image] which can be used with OpenStack. The image is based on the Fedora EC2 images, includes cloud-init and is a 200Mb download. == Essex Preview Repo For F-16 == Alan Pevec has started maintaining a [https://fedoraproject.org/wiki/Getting_started_with_OpenStack_on_Fedora_17#… "preview" repository for Essex on Fedora 16]. If you're running Fedora 16 and you want to try out the Essex release, this is the repo for you! Also Steve Dake [http://oss-us-1.clusterlabs.org/pipermail/pcmk-cloud/2012-March/000709.html summarized steps] for updating the OpenStack Diablo release to Essex on Fedora 16. == Devstack F-16 Support == Russell Bryant has been hard at working improving devstack's F-16 support in his [https://github.com/russellb/devstack/commits/fedora-support fedora-support branch in github]. This branch also adds support for using Qpid instead of RabbitMQ. == Keystone Fedora PAM Support == Russell also added [https://review.openstack.org/5365 PAM authentication support] for Keystone in Fedora. == Fedora Support in Puppet Labs Recipes == Derek Higgins has been working on adding Fedora support to Puppet Labs' recipes for OpenStack. Support was [Nova https://github.com/derekhiggins/puppetlabs-nova/commit/e66e5ab added to Nova]. Work [https://github.com/derekhiggins/puppetlabs-swift/commits/fedora_testing is underway for Swift]. And a whole bunch of dependent modules are also gaining Fedora support. These recipes are used by [http://smokestack.openstack.org upstream's Smokestack instance] when testing on Fedora. == iSCSI tgtd Issue With Systemd == A recent systemd update caused tgtd to hang for 5 minutes on startup. [http://pkgs.fedoraproject.org/gitweb/?p=scsi-target-utils.git;a=commitdiff;… Derek pushed this simple fix] for the problem. == cloud-init and OpenStack == We're now testing cloud-init with OpenStack a bit more. Pádraig Brady and Joe Brue filed these bugs: # [https://bugzilla.redhat.com/795998 #795998 - run-parts is run with the non-existent --regex option] # [https://bugzilla.redhat.com/750979 #750979 - cloud-init scripts do not make hostname changes permanent in /etc/sysconfig/network] and both have been fixed in recent updates. == Broken python-boto Update == OpenStack folks identified a [https://bugzilla.redhat.com/804041 serious python-boto issue] before update hit stable. = Upstream News = == OpenStack Governance Elections == The OpenStack project held its spring governance elections recently and elected technical leads for Nova, Swift, Glance, Keystone and Horizon. Two new members of the Project Policy Board were also elected. Two Fedora developers - Mark McLoughlin and Eoghan Glynn - were nominated for positions but, despite a hard-fought and emotional campaign, neither were elected. Next time! == Rewritten libvirt Driver XML Generation == Dan Berrange has posted a [https://lists.launchpad.net/openstack/msg08408.html massive patch set to Nova] for comments. The patches replaces Nova's usage of Cheetah templates for generating libvirt XML with a safer approach of de-serializing a DOM. Since this is such a large change, it will not be proposed until Folsom opens up. Dan also had these interesting fixes merged lately: # [https://review.openstack.org/5043 Remove the <acpi/> feature from UML/LXC guests] # [https://review.openstack.org/5076 Simply & unify console handling for libvirt drivers] # [https://review.openstack.org/5147 Use cache='none' for all disks] == libvirt Driver Image Handling == Pádraig continued improving the libvirt driver's image handling with these fixes: # [https://review.openstack.org/5442 ensure atomic manipulation of libvirt disk images] # [https://review.openstack.org/5456 allow the compute service to start with missing libvirt disks] == libvirt Issue Fixed in F-16, Broken in Ubuntu Oneric == [https://lists.launchpad.net/openstack/msg08581.html This report of a libvirt issue with OpenStack] is rather interesting. It turns out that this was an issue found upstream, fixed in Fedora 16 but is still broken in Ubuntu Oneric. Kudos to our libvirt package maintainers! == Rootwrap in Quantum == Rootwrap is a helper script added to Nova in Essex to help lock down the sudo commands that Nova can run. Bob Kukura has now [https://bugs.launchpad.net/quantum/+bug/948467 added rootwrap to Quantum] and, while doing so, ensured that the Quantum agents no longer need to run as root. = Blogs etc. = == Keystone Blog Posts == Adam also blogged on some other topics related to keystone: # [http://adam.younglogic.com/2012/03/keystone-should-move-to-apache-httpd/ Keystone should move to Apache HTTPD] # [http://adam.younglogic.com/2012/03/pki-for-keystone/ PKI for Keystone] # [http://adam.younglogic.com/2012/03/hateoas-openstack-keystone/ HATEOAS Openstack Keystone] == OpenStack, Deltacloud and CIMI == Marios Andreou, a developer on the deltacloud project, wrote [http://www.mariosandreou.com/deltacloud/cloud_API/2012/03/05/openstack-cimi… this interesting blog post on OpenStack Networking and CIMI]. [http://dmtf.org/standards/cloud CIMI] is a cloud API standard being developed by the DMTF and supported by the deltacloud project.
