OpenStack status

by Mark McLoughlin

- FUDCon Blacksburg is a short few days away: http://fedoraproject.org/wiki/FUDCon:Blacksburg_2012 http://fedoraproject.org/wiki/FUDCon:Blacksburg_2012_Cloudy_Plans Rumours abound of an OpenStack talk, an OpenStack hackfest, some upstream OpenStack developers attending and more! Those of us not lucky enough to be going look forward to hearing all about it :-) - A proposed schedule for the "Open Source Virtualization and Cloud" devroom at FOSDEM has been announced: https://lists.fosdem.org/pipermail/virt-cloud-devroom/2012-January/000018... A bunch of Fedora and OpenStack folks are going to be attending. - Russell reserved a date for the Fedora 17 OpenStack Test Day: http://lists.fedoraproject.org/pipermail/cloud/2011-December/001112.html http://fedoraproject.org/wiki/Test_Day:2012-03-08_OpenStack_Test_Day Preparations for the test day are in their early stages. Russell hopes we can significantly expand the set of test cases by the time the day comes around. - Rich wrote up a feature page covering the OpenStack F-17/Essex efforts: http://fedoraproject.org/wiki/Features/OpenStack_Essex - Pádraig added a feature page for libguestfs support in OpenStack: http://fedoraproject.org/wiki/Features/OpenStack_using_libguestfs and it was approved by FESCo: http://fedorahosted.org/fesco/ticket/732 He already got the patches to add this support included upstream: http://review.openstack.org/1993 http://review.openstack.org/1994 - Russell, with the help of William Henry, has been working on adding Qpid support to OpenStack. He has created a Fedora feature page for it here: http://fedoraproject.org/wiki/Features/OpenStack_using_Qpid The upstream blueprint is here: http://blueprints.launchpad.net/nova/+spec/apache-qpid-rpc Slightly related, Russell also got a patch upstream which avoids kombu being a required dependency for glance: http://review.openstack.org/2810 - Mark backported a bunch more fixes upstream from Nova and Glance's master branch to stable/diablo and then rebased the Fedora packages to include these fixes: http://admin.fedoraproject.org/updates/openstack-nova-2011.3-18.fc16 http://admin.fedoraproject.org/updates/openstack-glance-2011.3-4.fc16 The nova update also fixes this serious issue with Nova volumes: http://bugzilla.redhat.com/752709 Please to be testing these packages and giving them karma. - Some EPEL updates are in need of karma in epel-testing: http://admin.fedoraproject.org/updates/openstack-nova-2011.3-18.el6 http://admin.fedoraproject.org/updates/openstack-glance-2011.3-6.el6 And a couple of others have been pushed to stable recently: http://admin.fedoraproject.org/updates/openstack-keystone-2011.3.1-4.el6 http://admin.fedoraproject.org/updates/python-migrate-0.6-6.el6 Finally, to recap, here are the set of OpenStack related already in stable: http://admin.fedoraproject.org/updates/python-webob1.0-1.0.8-3.el6 http://admin.fedoraproject.org/updates/python-prettytable-0.5-2.el6 http://admin.fedoraproject.org/updates/python-eventlet-0.9.16-3.el6 http://admin.fedoraproject.org/updates/python-sqlalchemy0.7-0.7.3-4.el6 http://admin.fedoraproject.org/updates/python-nose1.1-1.1.2-4.el6 http://admin.fedoraproject.org/updates/python-novaclient-2.6.1-0.5.89bzr.el6 - Bob has started looking at Melange, how it interacts with Quantum and getting ready to package it for Fedora 17 Essex. One stumbling block is that Melange currently depends on openstack-common, which hasn't yet had a release. - Chris has been working on Open vSwitch packaging for Fedora and sent a bunch of cleanups upstream: http://openvswitch.org/pipermail/dev/2011-December/013632.html - GlusterFS folks are working on an "object storage plugin" for Swift: http://review.gluster.com/805 This involves a fairly invasive non-upstream set of changes to Swift to add a plugin mechanism. Figuring out a way for upstream to support plugins like this will be crucial to the sustainability of this feature and our ability to include it in Fedora. - There is talk upstream of a CloudAudit (http://cloudaudit.org) implementation being proposed for OpenStack: http://blueprints.launchpad.net/openstack-common/+spec/cloud-audit-api http://github.com/piston/openstack-cloudaudit - Discussions kicked off again around the formation of the OpenStack Foundation. These mails give a good sense of the current status: http://lists.openstack.org/pipermail/foundation/2012-January/000077.html http://lists.openstack.org/pipermail/foundation/2012-January/000087.html http://lists.openstack.org/pipermail/foundation/2012-January/000088.html - Mark has been working on getting a plan agreed for the openstack-common project: http://wiki.openstack.org/CommonLibrary It will be based on Jason Kölker's repository, but with much of the current API set removed until it is solid enough to commit to maintaining compatibility for it: http://github.com/jkoelker/openstack-common - Mark is getting ready to release Nova and Glance updates (i.e. 2011.3.1) from the upstream stable/diablo branch: http://wiki.openstack.org/StableBranchRelease The branches have roughly 80 and 20 fixes respectively since the diablo release in September. - Cole finally slogged his way through the gnarly issues he was having with Horizon and got it working end-to-end. He plans on continuing with Horizon packaging adding it as a F-17 Feature. - Russell added --yes, --rootpw and --novapw options to openstack-db-setup: http://lists.fedoraproject.org/pipermail/cloud/2011-December/001040.html - Russell has come up with a Plan(tm) for including newer python-xattr in Fedora: http://bugzilla.redhat.com/732692 - Steven Dake raised an interesting issue with networking hangs with a bridge that hasn't got a physical NIC enslaved to it: http://lists.fedoraproject.org/pipermail/cloud/2011-December/001116.html Alan Pevec pointed out the approach taken by libvirt to resolve this, which may also be appropriate for Nova: http://libvirt.org/git/?p=libvirt.git;a=commit;h=5754dbd - Pete Zaitcev packaged git-review, which is used by OpenStack developers to submit patches upstream: http://lists.fedoraproject.org/pipermail/cloud/2011-December/001119.html - Eoghan Glynn (of rhevm-api fame :-) has started poking at Glance, starting with the annoying issue of Glance PasteDeploy configuration being in the same files as user configuration: http://bugs.launchpad.net/glance/+bug/815208 - Pádraig has been working on updating some of the Fedora/EPEL relevant upstream wiki pages: http://wiki.openstack.org/Packaging/RHEL http://wiki.openstack.org/NovaInstall/RHEL6Notes http://wiki.openstack.org/NovaInstall/CentOSNotes - Dan Berrange shared his interesting plans to propose the use of libvirt-gconfig for Nova's libvirt XML generation: http://lists.launchpad.net/openstack/msg06531.html - Rich proposed some patches to libguestfs to better support OpenStack's use case: http://www.redhat.com/archives/libguestfs/2011-December/thread.html#00134 Rich and Matt clashed over the patches, eventually resolving their differences with sticks and knives. Well, not really, but it's an interesting thread :-) - Boris Filippov (of Grid Dynamics) posted some Nova patches for inclusion in the Fedora patches. After a little discussion, it was agreed that it was more appropriate to send them upstream: http://lists.fedoraproject.org/pipermail/cloud/2011-December/001077.html http://github.com/bfilippov/nova/commits/gd-patches Boris posted two of the patches to launchpad: http://bugs.launchpad.net/nova/+bug/904767 http://bugs.launchpad.net/nova/+bug/904724 and also to gerrit: https://review.openstack.org/2413 https://review.openstack.org/2414 but it looks like both patches were already fixed in master. - Saggi Mizrahi reported this glance dependency issue: https://bugzilla.redhat.com/759512 and Pádraig fixed it. - Ilkka Tengvall reported this issue with nova user creation: https://bugzilla.redhat.com/770927 and (again) Pádraig fixed it. - Russell add a LICENSE file and man pages to the glance tarball upstream. These were issues identified during the glance Fedora package review: http://review.openstack.org/2743 http://review.openstack.org/2765

Re: EC2 AMI Test Case Review Request

I see what you mean but I'm a little hesitant to add those kind of details to the test case. It might be better to have a separate wiki page for "getting started with EC2" instructions. I'll look around to see if there is already a page like that. > Perhaps adding in a comment saying: "As setting up a first-time AWS > account can take sometimes a few hours, it is recommended that the > user create this in advance."

I'm honestly not sure how to do that, will look into whether or not it's possible, though. Thanks, Tim

Re: OpenNebula approved

by Denis Arnaud

Dear Jaime, We're a few weeks away from F17 features submission deadline and we've been > working hard (especially Shaw Starr - CC) in submitting OpenNebula package > dependencies. OpenNebula would even work without those not yet complete > dependencies since they're mostly ruby gems which speed up OpenNebula > (although we're confident they will all be there for the submission > deadline), so we would like to move on to the next stage and start > submitting OpenNebula for feature review to get it approved. Could anyone > help us out with the process we must follow to get OpenNebula to be an > accepted feature? > AFAIU, you can submit the feature for approval by Fesco. There should be a Fesco meeting tonight, I believe. As a reminder, the feature process is described on the Fedora Wiki: https://fedoraproject.org/wiki/Features/Policy. In particular, the acceptance criteria ( https://fedoraproject.org/wiki/Features/Policy/Acceptance) seem all be met by OpenNebula. All the tasks of the feature are not required to be completed for the feature approval. Rather, they need to be completed for the Fedora 17 freeze (which will come shortly). So, regarding the acceptance process, the only thing you have to do *for now * (https://fedoraproject.org/wiki/Features/Policy/Milestones), is: "1. The Feature Owner adds the feature page to Category:FeatureReadyForWrangler<https://fedoraproject.org/wiki/Category:FeatureReadyForWrangler>by adding the following text to the bottom of their feature page: *Category:FeatureReadyForWrangler<https://fedoraproject.org/wiki/Category:FeatureReadyForWrangler> *--it is already in the feature template<https://fedoraproject.org/wiki/Features/EmptyTemplate> ." Note that you can also refer to the features submitted by similar projects: OpenStack (https://fedoraproject.org/wiki/Features/OpenStack), ( https://fedoraproject.org/wiki/Features/Aeolus_Conductor), Sheepdog ( https://fedoraproject.org/wiki/Features/Sheepdog) and HekaFS ( https://fedoraproject.org/wiki/Features/HekaFS) for Fedora 16, as well as BoxGrinder (https://fedoraproject.org/wiki/Features/BoxGrinder) for Fedora 15. Does it seem clearer? Best regards Denis

Problem with OpenStack Getting Started Guide

by Steven Dake

The getting started guide is missing the assignment to the em1 interface in the initial ip address range setup. This results in flakey network behavior when VMs are terminated. Analysis of problem: With default guide settings, assume two VMs are run via euca-run-instances. The first VM will get a vnet with a mac address. It will then be added directly into the bridge. The bridge will then take the MAC of the vnet0 interface. Then the second VM will start and get a vnet1 with an assigned MAC address. Killing the first VM that was started (which has a MAC address equal to the br0) will cause deletion of vnet0 and cause the bridge driver to flush the arp table and choose a new bridge interface. This results in disconnection of the remaining VM for 30-60 seconds. A simple solution is to specify a physical bridge interface during bridge creation ie: sudo nova-manage network create markmc 10.0.0.0/24 --bridge=br0 --bridge_interface=em1 This is shown for the compute nodes, but not the controller nodes. With this setting, br0 will always be assigned the MAC address of the bridge interface. Then terminating VMs will not result in the arp table being flushed, and loss of network connectivity. This is shown in the "controller" section of the getting started guide when using compute nodes, but not in the initial setup. Note if vnet0 VM is killed, then the br0 will adopt the mac address of vnet1. Then if vnet1 is killed the network will stall for 30-60 seconds and lose the arp table (while killing the VM associated with vnet0 will have no impact on the network). This does raise the question what to do when em1 is taken out of service. This will cause the bridge driver to flush the arp table and pick a new device (vnet0) resulting in again flakey behavior with the bridges when stopping virtual machines. Just learning the ins and outs of bridges today I don't have a good recommendation for a solution to this "em1 taken out of service" problem. One idea I had was changing nova to add a "dummy" vnet0 before adding em1 or any of the VM vnets (during br0 creation in nova-network). I'm not sure if this would cause traffic to bridge out of the physical interface properly, but it would fix the network connectivity issues and arp table killing that occurs while a new bridge MAC is chosen. Now off to PTO. Regards -steve

Cloudy Forecast at FUDCon Blacksburg

by Robyn Bergeron

Hi guys, I realize many of us are on vacation this week but I'm shipping this out in the hopes of getting something organized before the last second, since I am pretty sure I will have plenty of other ohgodlastsecond things to do come FUDCon time. I know that Matt Domsch had previously sent an email about getting together an OpenStack workshop/hackfest while we're at FUDCon. We also presumably have folks planning on doing OTHER THINGS, so, feel free to list your plans, wishes, hopes, dreams, and so forth. Conveniently, I have a wiki page set up for this! https://fedoraproject.org/wiki/FUDCon:Blacksburg_2012_Cloudy_Plans Once we have some stuff listed in the way of workshops/hackfests I'll reserve our room spots for Friday and/or Sunday, hopefully in a non-overlapping kind of way. And so: Garrett, Andy, Greg, Perry, Russell, David, Mike, Matt, Clint, Justin, John Mark, Marek, Karsten, Jeff, Kaleb (???), and anyone I missed, (that's gholms, mull, gregdek, pmyers, drumkilla (I REFUSE TO CALL YOU RUSSELLB), ke4qqq, mmcgrath, mdomsch, herlo, jforbes, johnmark, mgoldmann, quaid, jdarcy, kkeithley for those playing along at home) ...... Get your stuff listed! :) -Robyn

Please test git-review RPM

by Pete Zaitcev

Dear All: I am thinking about packaging git-review (the real one, not Facebook's), and to that end I prepared RPMs that are to be submitted for Fedora. Before I do that, I'd like someone verify that they work. AFAIK both Gluster and OpenStack use Gerrit with git-review. These RPMs come from OpenStack source, and I am very curious if they are compatible with Gluster use, so that we can have one in Fedora. http://people.redhat.com/zaitcev/linux/git-review-1.8-1.fc16.noarch.rpm http://people.redhat.com/zaitcev/linux/git-review-1.8-1.fc16.src.rpm Thanks and have a happy New Year, -- Pete
