[libvirt] Happy Birthday Libvirt
by Daniel Veillard 02 Nov '15

02 Nov '15

Hello everybody, as the first commits were done on Nov 2 2005, libvirt is more or less ten years old. This has been quite a bit of a journey, but a very successful one in my opinion, the initial goal was to provide a long term stable API for virtualization in the Red Hat ecosystem, and I'm very happy to see the goal has been reached, and we went way beyond that. In the end I think libvirt helped avoid the "balkanization" which is classic in highly competitive domains where you end up with one vertical set of tools per vendor. I also think that libvirt played a key role to keep free and open source software in the main virtualization offerings and even more so for cloud management systems. So it's time to celebrate, there is obviously lot to be done still on libvirt (as the steady stream of patches show !), but I would like to thank everybody who has contributed to the project so far, with a special mention to Dan Berrange who has been leading the effort technically for most of that time. I would also say that I have been very pelased with how the project has been working in that decade, the community is technical but friendly, and it's my hope libvirt, the project as well as the code, will remain as successful for the next decade ! So Thank You everybody, for making this project and community successful ! Enjoy that very special day :-) Daniel -- Daniel Veillard | Open Source and Standards, Red Hat veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] [PATCH 0/8] Few vfio related fixes
by Shivaprasad G Bhat 02 Nov '15

02 Nov '15

The series fixes 3 issues which lead to host crash. The actual fixes are in p3, p4, p7 and p8. I'll fill in more details / descriptions in v2. The make check fails on virpcitest now, which I am still debugging. I anticipate some rework from review on p7 which I continue to refine. Sending now, to get any feedback that might change things drastically. --- Shivaprasad G Bhat (8): Initialize the stubDriver of pci devices if bound to a valid one Add iommu group number info to virPCIDevice Refuse to reattach from vfio if the iommu group is in use by any domain Wait for vfio-pci device cleanups before reassinging the device to host driver Split reprobe action from the virPCIUnbindFromStub into a new function Pass activeDevs and inactiveDevs to virPCIDeviceUnbindFromStub and virPCIDeviceBindToStub Postpone reprobing till all the devices in iommu group are unbound from vfio Wait for iommmu device to go away before reprobing the host driver src/util/virhostdev.c | 18 ++++ src/util/virpci.c | 206 ++++++++++++++++++++++++++++++++++++++----------- 2 files changed, 177 insertions(+), 47 deletions(-) -- Signature

[libvirt] Entering freeze for libvirt-1.2.21
by Daniel Veillard 02 Nov '15

02 Nov '15

As pointed our on Tuesday it's time for a new release. I have tagged the release candidate 1 in git and pushed signed tarball and rpms to the usual place at: ftp://libvirt.org/libvirt/ Based on my limited testing this works just fine, but that's very limited and doesn't test portability at all, so please give it a try ! I will likely push rc2 on the week-end and the final version on Tuesday or Wednesday, please raise issues if you fine any, thanks, Daniel -- Daniel Veillard | Open Source and Standards, Red Hat veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] Outreachy 2015 DecemberMarch- Enhancing libvirt-designer
by Riyafa Abdul Hameed 01 Nov '15

01 Nov '15

Dear sir, I am Computer Science and Engineering undergraduate at University of Moratuwa, Sri Lanka. I am a keen learner and am much interested in open source. I have worked with WSO2 <http://wso2.com/> on open source projects and am quite familiar with FOSS development. I have a good knowledge in C and in using XML. I would like to participate in "Outreachy 2015 DecemberMarch" with QEMU, but it was already quite late when I came to know of this program as its application deadline closes by tomorrow. I would like to apply for the project "Enhancing libvirt-designer" this time for Outreachy. I sent a mail to the mentor, Michal Privoznik and I couldn't get in touch with him. Because it is already too late can anyone please suggest what I can do before I apply for the program by tomorrow? Thank you. Yours sincerely, Riyafa -- Riyafa Abdul Hameed Undergraduate, University of Moratuwa Email: riyafa3(a)gmail.com Website: https://riyafa.wordpress.com/ <http://riyafa.wordpress.com/> <http://facebook.com/riyafa.ahf> <http://lk.linkedin.com/in/riyafa> <http://twitter.com/Riyafa1>
