CentOS-7 / powerpc BE bring up
by Karanbir Singh 14 Sep '15

14 Sep '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hi Ashish, Fabian is putting together a VM ( or 2 if you need more ), for the BE bringup. This would be a fedora19 VM. Fabian: Ashish has confirmed that he has all the mock configs required to bringup the CentOS 7.1406 os/ release content, then build the updates upto May 2015 content. So here is what I see happening, 1) Fabian to setup a VM for ppc64 BE 2) Fabian to setup a VM for ppc ( multilib, 32 bit ) 3) Ashish to file a bug report at bugs.centos.org to req direct access, include ssh key 4) Fabian to get Ashish setup, and get Ashish an account on the ipv4 jumphost. 5) One that is in place, Ashish to build mock itself on the machines for either 64bit or 32bit 6) Fabian to let Ashish know the mirror url for fedora19, which would be the base of the builds 7) Ashish should then be able to kick off the first bringup cycle, with mock configs he already has in place. 8) build to CentOS-7 1406 content being complete. 9) Checkpoint at this stage, to evaluate payload, build process, build delivery and workout path to automating builds from there on. We are going to use the centos-devel mailing list for communications, and irc channel #centos-ppc I am going to once again request everyone to keep AWAY from private conversations, and stick to the community visible avenues, so we can all track ( and help! ) as things evolve. We can repeat the same process for LE, s/Ashish/James/ for that. I would defer to letting Ashish and James to include other people in the process as needed, however - all user accounts MUST be created via the bugs.centos.org process, and its important that Fabian is able to execute the creation + access ( so its logged and auditable ). Once we have step-5 in place, we can engage with Jim Perrin, and workout the modalities and process of including the effort into the CentOS AltArch SIG - which would give us a distro, test, delivery proces s. does this work for everyone involved here ? regards, - -- Karanbir Singh, Project Lead, The CentOS Project +44-207-0999389 | http://www.centos.org/ | twitter.com/CentOS GnuPG Key : http://www.karan.org/publickey.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQEcBAEBAgAGBQJV8ro0AAoJEI3Oi2Mx7xbtdV8IAIJTE2kiEXZNUpWo5K+q0OMh ArYZCdquv/ZHD6/HqO0Q3IkeuBEacm/yxtoAyDF3fE3j6TvO4WT1zmpAxGq3RtAS 0PwTqTjeqoFChXxmHu17IwSDgCCCtZr8KKQgbT42RYWdMtU01jFC/LxM1PPOfABR 4adO74Gp1Pl+Zprxd8x384nH3bppUq0Br7sz0jyIWG3AKgBchRoRwvIBnj6//zqo wkX9KtajxtpmJPrZh1n0ZKndyDiXAMWDkUTk6YQX4aVOqOI5ELgjjKiiR7GY1NFy NPSI/7lNLjyDtehl+NpcwJ+6UWd8oLTltA885f0ieSGfiuMOTb7+vBq9tA/R+cI= =Vrbc -----END PGP SIGNATURE-----

CentOS-7 / ppc64le System Architectures
by Aaron Sullivan 13 Sep '15

13 Sep '15

This message is intended as follow-up to this thread: https://lists.centos.org/pipermail/centos-devel/2015-September/013792.html Rackspace is building a POWER8 based OpenPOWER server, in an Open Compute form factor. Its codename is Barreleye. Specs and target use cases are as follows: Specs: * CPU / Memory o 2 sockets o 32 DIMM slots o 8 Centaurs * IO o 2 x8 OCP Mezzanine slots o 1 x16 FHFL PCI-E slot o 1 x8 HHFL PCI-E slot o 1 x8 HHHL PCI-E slot * Storage o Systems are currently using LSI / Avago 3108 ROCs (9361-8i), but could support other ROCs o LSI / Avago SAS Expander o 15 x2.5" hot swap drives o 1 internal M.2 SATA card slot * BMC o AST2400 Chip, with internal development targeting OpenBMC ? More here: http://www.datacenterknowledge.com/archives/2015/08/14/facebooks-openbmc-ca… -- there's similar, collaborative work going on for Barreleye. There's a picture of a Barreleye rack, at Rackspace, here: https://twitter.com/Calista_Redmond/status/636367178355245056/photo/1 Use cases: * OpenStack with KVM (for an IaaS platform) * Container Platform (LXC, Docker, etc) * Bare metal host for popular applications like LAMP, Nginx, Wordpress, Go environments, and so forth * Big data apps starting with Mongo, but also including Cassandra, Redis, Hadoop, and Spark * CAPI accelerator environments We believe demand for POWER-based CentOS will be similar to our x86 demand (which is to say, significant). We hope to see it get to launch-grade quality for at least virtual machines, if not bare metal, over the next few months. --Aaron [outlook-signature-distinguished]

Problem creating CentOS cloud image, selinux bug with cloud-init?
by Sebastiaan Glazenborg 11 Sep '15

11 Sep '15

Hello, I am trying to build my own CentOS cloud image, one reason is to better understand this process and learn from it, but am having troubles completing a fully functional image. I have read various how-to and other documentation but I keep running in to the same issue, maybe a bug? Very interested in how the CentOS cloud images were created and if the people building these ran in to the same issue. I am following these few steps: 1. create new CentOS 7 installation using virt-install and a kickstart to create base_image. nothing special is done, just using the CentOS 7 iso contents to do a minimal install + cloud-init 2. run virt-sysprep on this created base_image 3. create new kvm vm using a copy of the sysprepped disk file Because I do this all locally on my laptop I am using a config-drive iso that cloud-init is using to read meta-data and user-data files. The newly created vm is booted up, console connected, and the arrives at the prompt without having completed the various cloud-init steps. <snip boot messages> [ 6.683676] ip_tables: (C) 2000-2006 Netfilter Core Team [ 6.823284] nf_conntrack version 0.5.0 (7947 buckets, 31788 max) [ 6.885987] ip6_tables: (C) 2000-2006 Netfilter Core Team [ 7.076775] Ebtables v2.0 registered [ 7.099351] Bridge firewalling registered cloud-init[576]: Cloud-init v. 0.7.5 running 'init-local' at Fri, 11 Sep 2015 20:02:31 +0000.

Re: [CentOS-devel] CentOS-7 / powerpc BE bring up
by Lance Albertson 11 Sep '15

11 Sep '15

[I just subscribed to the list, so bare with me and sorry for the top post] I have a lot of interest in getting CentOS ppc64le going for here at the lab. For now I'd prefer having LE over BE as that is where most of the arch seems to be going. If there's anything I can do to help with this process, please let me know. I've had a lot of experience in the past several years with this architecture on Fedora. Thanks! <snip> > does this work for everyone involved here ? What's the outlook for > getting LE VMs so that the this started as well. I'm getting lots of pressure > for LE CentOS from customers, partners, and clients. Perhaps we can get folks who have shown interest in having Power on CentOS to post their preferred architecture here? -- Lance Albertson Director Oregon State University | Open Source Lab

CentOS 7 on power64 status
by James O'Connor 11 Sep '15

11 Sep '15

Just an email to summarize where we stand with CentOS 7 ppc64le (Little Endian) and ppc64 (Big Endian). We don’t have an official CentOS power64 SIG yet but I am interested in enlisting further community participation and testing when the time is appropriate. I have working proof of concept builds of c7-ppc64le and c7-ppc64. Both ports were done using Fedora 22 based PowerKVM guests. The LE port was done cleanly and involved developing a c7 based Linux From Scratch toolchain to get around a thorny issue with glibc-2.20 in Fedora 21 LE but glibc-2.17 in CentOS 7. This issue further prevents the use of Fedora 21 LE rpms because they all require GLIBC_2.18 and c7 provides GLIBC_2.17. The BE port is much more straightforward as Fedora 19 ppc64/ppc rpms are used to bootstrap the initial CentOS 7 ppc64/ppc rpms. As of yesterday we have IBM POWER8 systems up and running PowerKVM in the CentOS datacenter. Similar development and test systems are available at http://osuosl.org/ Work is underway to get Fedora ppc64le and ppc64 builders up and running and replicate the proof of concept builds. Stay tuned to the centos-devel email list or drop by #centos-ppc on irc.freenode.net to say hello.

Announcing a New CentOS Atomic Host Release
by Jason Brooks 10 Sep '15

10 Sep '15

Today we’re releasing a significant update to the CentOS Atomic Host (version 7.20150908), a lean operating system designed to run Docker containers, built from standard CentOS 7 RPMs, and tracking the component versions included in Red Hat Enterprise Linux Atomic Host. CentOS Atomic Host is available as a VirtualBox or libvirt-formatted Vagrant box, as an installable ISO image, as a qcow2 image, or as an Amazon Machine Image. These images are available for download at http://cloud.centos.org/centos/7/atomic/images/. The backing ostree repo is published to http://mirror.centos.org/centos/7/atomic/x86_64/repo. Currently, the CentOS Atomic Host includes these core component versions: - kernel 3.10.0-229 - docker 1.7.1-108 - kubernetes 1.0.0-0.8.gitb2dafda - etcd 2.0.13-2 - flannel 0.2.0-10 - cloud-init 0.7.5-10 - ostree 2015.6-4 - atomic 1.0-108 Upgrading --------- If you’re running the version of CentOS Atomic Host that shipped in June, you can upgrade to the current image by running the following command: $ sudo atomic host upgrade If you’re currently run the older, test version of the CentOS Atomic Host, or if you’re running any other atomic host (from any distro or release in the past), you can rebase to this released CentOS Atomic Host by running the following two commands : $ sudo ostree remote add centos-atomic-host \ http://mirror.centos.org/centos/7/atomic/x86_64/repo $ sudo rpm-ostree rebase \ centos-atomic-host:centos-atomic-host/7/x86_64/standard Images ------ ### Vagrant CentOS-Atomic-Host-7-Vagrant-Libvirt.box (393 MB) and CentOS-Atomic-Host-7-Vagrant-Virtualbox.box (404 MB) are Vagrant boxes for Libvirt and Virtualbox providers. The easiest way to consume these images is via the Atlas / Vagrant Cloud setup (see https://atlas.hashicorp.com/centos/boxes/atomic-host) For example, getting the VirtualBox instance up would involve running the following two commands on a machine with vagrant installed: $ vagrant init centos/atomic-host && vagrant up --provider virtualbox ### ISO The installer ISO (682 MB) can be used via regular install methods (PXE, CD, USB image, etc.) and uses the Anaconda installer to deliver the CentOS Atomic Host. This allows flexibility to control the install using kickstarts and define custom storage, networking and user accounts. This is the recommended process for getting CentOS Atomic Host onto bare metal machines, or to generate your own image sets for custom environments. ### QCOW2 The CentOS-Atomic-Host-7-GenericCloud.qcow2 (922 MB) is suitable for use in on-premise and local virtualized environments. We test this on OpenStack, AWS and local Libvirt installs. If your virtualization platform does not provide its own cloud-init metadata source, you can create your own (http://www.projectatomic.io/blog/2014/10/getting-started-with-cloud-init/) NoCloud iso image. The Generic Cloud image is also available compressed in gz (389 MB) and xz compressed (303 MB) formats. ### Amazon Machine Images Region Image ID ------ -------- sa-east-1 ami-47ed785a ap-northeast-1 ami-3458d234 ap-southeast-2 ami-05511e3f us-west-2 ami-a5b6ab95 ap-southeast-1 ami-dc99938e eu-central-1 ami-8c111191 eu-west-1 ami-0b6e4d7c us-west-1 ami-69679d2d us-east-1 ami-69c3aa0c ### SHA Sums a132d59732e758012029a646c466227f4ecf0c71cc42f0a10d3672908e463c0c CentOS-Atomic-Host-7.20150908-GenericCloud.qcow2 aad5d39e0683dc997f34902b068c7373aac3f7dc9b2c962a6ac0fe7394e2aa58 CentOS-Atomic-Host-7.20150908-GenericCloud.qcow2.gz c8432175a012e7f13b7005fe9c1fe43e03e47ca433db8230ab6d5d1831d2cbe0 CentOS-Atomic-Host-7.20150908-GenericCloud.qcow2.xz b222702942d02da2204581de6f877cf93289459a99f9080e29016e3b90328098 CentOS-Atomic-Host-7.20150908-Installer.iso 5531fa99429b38c6e6c4aca87672bd5990ab90f6445cc0e55c9121ad62229141 CentOS-Atomic-Host-7.20150908-Vagrant-Libvirt.box bdcf58772117dd3a84100e5902f4f345daeea7c04f057c0ab6e29bfef3c82eab CentOS-Atomic-Host-7.20150908-Vagrant-Virtualbox.box Release Cycle ------------- The rebuild image will follow the upstream Red Hat Enterprise Linux Atomic Host cadence. After sources are released, they’ll be rebuild and included in new images. After the images are tested by the SIG and deemed ready, they’ll be announced. If you’d like to help with the process, there’s plenty to do! Getting Involved ---------------- CentOS Atomic Host is produced by the CentOS Atomic SIG (http://wiki.centos.org/SpecialInterestGroup/Atomic) based on upstream work from Project Atomic (http://www.projectatomic.io/) If you’d like to work on testing images, help with packaging, documentation, or even help define the direction of our releases — join us! The SIG meets weekly on Thursdays at 16:00 UTC in the #centos-devel channel, and you’ll often find us in #atomic and/or #centos-devel if you have questions. You can also join the atomic-devel (https://lists.projectatomic.io/mailman/listinfo/atomic-devel) mailing list if you’d like to discuss the direction of Project Atomic, its components, or have other questions. Getting Help ------------ If you run into any problems with the images or components, feel free to ask on the centos-devel (http://lists.centos.org/mailman/listinfo/centos-devel) mailing list. Have questions about using Atomic? See the atomic mailing list (https://lists.projectatomic.io/mailman/listinfo/atomic) or find us in the #atomic channel on Freenode.

Atomic SIG: Joint Test Day with Fedora Atomic Folks
by Dusty Mabe 10 Sep '15

10 Sep '15

Hi All, There has been some discussion of doing a joint test day with Fedora and CentOS atomic folks. Fedora is having a test day for Fedora Cloud base on 9/8 (all are welcome to join us). We were thinking about having the joint Fedora/CentOS test day on the following Tuesday (9/15). Is this something everyone is interested in? To do the test day it would be worth having a test day page like [1] and some test cases for people to execute. These test cases can probably overlap with the one's fedora has.
