initscripts-9.03.38-1.el6.centos.1.src.rpm missing?
by Nathaniel W. Turner 24 Mar '13

24 Mar '13

I see that the mirror currently has a binary initscripts-9.03.38-1.el6.centos.1.x86_64.rpm, but I don't see the corresponding initscripts-9.03.38-1.el6.centos.1.src.rpm at http://vault.centos.org/6.4/os/Source/SPackages/ --- am I looking in the wrong place? -- Nathaniel W.

Missing packages in CentOS 6.4 x86_64
by John Newbigin 22 Mar '13

22 Mar '13

Hi, This may be by design or there may be a reason for it which I don't know. In the x86_64 repository for CentOS 6.4, the i686 version of these packages below are not up to date. This causes yum to complain about 'Protected multilib versions'. * iscsi-initiator-utils-6.2.0.873-2.el6 * iscsi-initiator-utils-devel-6.2.0.873-2 * control-center-filesystem-2.28.1-38 There may be others but these are the three I had to fix manually on my system. I just downloaded the i686 versions from the i386 repository which seem to work fine.

an upstream cloud-init
by Karanbir Singh 15 Mar '13

15 Mar '13

Hi, http://ftp.redhat.com/redhat/linux/enterprise/6Server/en/RH-COMMON/ Seems to have come online recently ( thanks ghoms for pointing at it ). target seems to be cloud-init and its deps, and only its deps ( they are conveniently marked with a .1 upgrade from corrosponding packages in EPEL ). But the name is interesting, What is is going to show up there ? and what sort of machine roles is the corrosponding repo being exposed to ? I've build the rpms to : https://nazar.karan.org/results/misc/cloud-init/20130315000927/ so feel free to play for now. Can anyone shed any light on the questions ? So we can then make a decision and see howto rope these into the distro repos in the best manner. Also, I suspect epel will need to either do something about these deps ( and they have an older 0.6 based cloud-init there ) - KB -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

Adding Linux Test Project content to our tests
by Karanbir Singh 14 Mar '13

14 Mar '13

hi, http://ltp.sourceforge.net/ "The Linux™ Test Project is a joint project started by SGI™ and maintained by IBM®, that has a goal to deliver test suites to the open source community that validate the reliability, robustness, and stability of Linux. The LTP testsuite contains a collection of tools for testing the Linux kernel and related features." ----------- In the week leading upto 6.4, Christoph Galuschka and I had started looking at how we might be able to integrate those tests into what we are doing. Since the 6.4 sprint kicked in, we resorted to just running the tests manually; Which worked well. However, I feel its worth putting these tests into the harness we have in place, and making sure they are run whenever we call for 'distro tests' or 'update tests'. One option is to have the entire suite run as a single tests/r_ltp/ suiet under t_functional; the other is to either have its own suite, we can directly import from upstream, or have it be a part of the t_external/ test suite ( along with the likes of wordpress / drupal and other things ). Thoughts ? - KB -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

Testing Nightly and Status Board
by Karanbir Singh 14 Mar '13

14 Mar '13

hi, At the moment, we run tests on a nightly basis, only in kvm vm's and the results dont go very far. I'd like to propose we use the entire QA bladecenter and run the entire compliment of deploys and tests, then post them in a status board which has some history ( stashboard ? ) Going one step further, we should run the entire t_functional tests as well as start incorporating some of the, now stale, t_external tests. At the moment we do deploys over http and nfs, to local and remote storage, under Xen, KVM, bare-metal and some virtualbox and some vmware hypervisors, for i386 and x86_64. I had a brief chat with Fabian about this yesterday, and we both think its doable, in the short term. Anyone else have thoughts about this ? or want to propose reporting mechanisms that might be better in line with the intended result : to give people a single perspective on the state of things, as a confidence point. And also to allow people to easily add tests that are then run nightly, so they can address their own corner cases.

qemu-kvm upgrade path is broken
by Morten Stevens 10 Mar '13

10 Mar '13

Hi, There is an upgrade problem with the latest qemu-kvm package for CentOS-6.4: Upgrading from qemu-kvm-0.12.1.2-2.355.el6_4_4.1.x86_64.rpm to the latest qemu-kvm-0.12.1.2-2.355.el6_4.2.x86_64.rpm package is not possible with "yum update". The problem is: qemu-kvm-0.12.1.2-2.355.el6_4_4.1.x86_64.rpm This package contains el6_4_4.1 instead of el6_4.1. Best regards, Morten

It just won't migrate a vm started on 6.4 to any host running 6.3.
