The problem was that libvirt 1.2.8 "failed to load module /usr/lib64/libvirt/connection-driver/libvirt_driver_qemu.so" and "/usr/lib64/libvirt/connection-driver/libvirt_driver_qemu.so: undefined symbol: virStorageFileCreate".

xapi for centOS 6.6
by Gautam Malu 26 Mar '15

26 Mar '15

Hi, I am a masters student at IIIT Hyderabad, India. I am writing a GOSC proposal for CentOS organization. It's about delivering a custom installer ISO which delivers Xen 4.4 stack on CentOS 6. full proposal: http://www.google-melange.com/gsoc/proposal/public/google/gsoc2015/gautam_m… I want to port xapi on CentOS 6 as part of it. There has been some previous efforts to port xapi on CentOS 6 but nothing official, as follows: http://wiki.xen.org/wiki/XAPI_On_CentOS_6 https://github.com/JohnGarbutt/xen-api-devinstall http://wiki.xenproject.org/wiki/Ceph_and_libvirt_technology_preview i was wondering if there is any other project going on to port xapi on CentOS 6 > CentOS 6.3 with XenServer being fully open source now. Best regards, Gautam Malu

koji build failure
by George Dunlap 26 Mar '15

26 Mar '15

Sometime back in January I submitted the then-current Xen4CentOS dom0 package to build in the CBS for C6, and it worked out of the box: https://cbs.centos.org/koji/buildinfo?buildID=601 After finishing up my mad month of writing slides, my holiday, and then clearing my developer backlog, I tried again with the most recent kernel version, and it failed: https://cbs.centos.org/koji/buildinfo?buildID=851 I looked at a diff between the two specfiles, and couldn't see anything that might have prompted this change; so I went back to try to build the same SRPM I built back in January; and it also failed in exactly the same way: https://cbs.centos.org/koji/taskinfo?taskID=8943 I did subsequently build a new set of xen packages, so it's not an issue with the build system in general, just an issue with the kernel package. The actual error message is this one: DEBUG util.py:333: Executing command: ['/usr/bin/yum', '--installroot', '/var/lib/mock/virt6-el6-build-1391-2327/root/', 'groupinstall', 'build', '--setopt=tsflags=nocontexts'] with env {'LANG': 'en_GB', 'TERM': 'vt100', 'SHELL': '/bin/bash', 'LC_MESSAGES': 'C', 'PROMPT_COMMAND': 'echo -n "<mock-chroot>"', 'PATH': '/usr/bin:/bin:/usr/sbin:/sbin', 'HOME': '/builddir', 'HOSTNAME': 'mock'} DEBUG util.py:283: Error: Package: glibc-headers-2.12-1.149.el6.i686 (build) DEBUG util.py:283: Requires: kernel-headers >= 2.2.1 DEBUG util.py:283: You could try using --skip-broken to work around the problem DEBUG util.py:283: You could try running: rpm -Va --nofiles --nodigest DEBUG util.py:283: Error: Package: glibc-headers-2.12-1.149.el6.i686 (build) DEBUG util.py:283: Requires: kernel-headers DEBUG util.py:373: Child return code was: 1 I feel a bit dumb here, but I really have no idea what koji or mock are doing, so I have no real idea how to proceed to debug what's going on here. Can anyone give me a hand? -George

25 Mar '15

Hi, I have submitted my proposal for the above said idea. I have researched about this from past two weeks, put the proposed workflow in the proposal. I am in contact with Karsten from last two weeks. However I have not added exact implementation details about tools, which will be better if mentor discusses first. Please suggest changes.

GSoC RootFS Build Factory Idea
by Mandar Joshi 24 Mar '15

24 Mar '15

Hello everyone, With this email I am hoping to reach a wider audience than with the one I sent to centos-gsoc at centos.org. I sent my introduction mail few days ago [1] and sent another email when I finished the draft of my proposal [2]. I haven't received any feedback and that has got me thinking if I've made a mess of the problem statement. I would really appreciate it if someone could give a quick read to my proposal. You can read it here [3]. I don't see much enthusiasm about the project. Is it because CentOS for ARM is not yet available and the ETA is not known? I hope it's not the case as I spoke to Evolution on IRC at Freenode and he is working hard on it. Says he could have it ready as early as April 1st. I know I am a bit late in asking for asking. Should have had it ready at least a week earlier.
