[libvirt] [libvirt-glib/libvirt-gconfig 00/17] Graphics: Introduce the new Remote and Local classes (and also implement a few missing methods).
by Fabiano Fidêncio 06 Sep '16

06 Sep '16

While trying to use libvirt-gobject and libvirt-gconfig for accessing VMs and looking at their config, instead of using libvirt and parsing XML directly, I found out that a few methods have been missing and that libvirt-gconfig is not exactly thought for the "reading their config" use case (see more explanations on the 10th and 14th commits. This series, unfortunately, introduces an ABI breakage.

[libvirt] [PATCH] conf: Fix initialization value of 'multi' in PCI address
by Xian Han Yu 04 Sep '16

04 Sep '16

The 'multi' element in PCI address struct used as 'virTristateSwitch', and its default value is 'VIR_TRISTATE_SWITCH_ABSENT'. Current PCI process use 'false' to initialization 'multi', which is ambiguously for assignment or comparison. This patch use '{0}' to initialize the whole PCI address struct, which fix the 'multi' initialization and makes code more simplify and explicitly.

[libvirt] [PATCH V2] virpci: support driver_override sysfs interface
by Jim Fehlig 02 Sep '16

02 Sep '16

libvirt uses the new_id PCI sysfs interface to bind a PCI stub driver to a PCI device. The new_id interface is known to be buggy and racey, hence a more deterministic interface was introduced in the 3.12 kernel: driver_override. For more details see https://www.redhat.com/archives/libvir-list/2016-June/msg02124.html This patch adds support for the driver_override interface by - adding new virPCIDevice{BindTo,UnbindFrom}StubWithOverride functions that use the driver_override interface - renames the existing virPCIDevice{BindTo,UnbindFrom}Stub functions to virPCIDevice{BindTo,UnbindFrom}StubWithNewid to perserve existing behavior on new_id interface - changes virPCIDevice{BindTo,UnbindFrom}Stub function to call one of the above depending on availability of driver_override The patch includes a bit of duplicate code, but allows for easily dropping the new_id code once support for older kernels is no longer desired.

[libvirt] wiki accounts for GSOC submissions
by Cole Robinson 02 Sep '16

02 Sep '16

Next week is the time for GSOC students to submit their Final Evaluations. Work needs to be hosted/linked from a public URL. Cedric suggested using the libvirt wiki for these pages, so something like: http://wiki.libvirt.org/page/Google_Summer_of_Code_2016/My_Page_Title And then we can link it from the top level Google_Summer_of_Code_2016 as well. But this means GSOC students will need wiki accounts which needs admin intervention. GSOC students: if you don't already have libvirt wiki accounts, please respond here with your desired username and email and one of the wiki admins will set you up. Thanks, Cole

[libvirt] Entering freeze for libvirt-2.2.0
by Daniel Veillard 02 Sep '16

02 Sep '16

Nearly that the time scheduled, I just tagged 2.2.0 release candidate 1 in git and masigned talbal and rpms at the usual place: ftp://libvirt.org/libvirt/ Seems to be working fine with my limited testing, it's also the first time I see *everything* green in ci.centos.org/view/libvirt-project/ ! :-) Nonetheless this should get some more serious testing, for example on other architectures, and assuming everything goes fine, rc2 will go out on Tuesday and 2.2.0 final should be available on Sep 1st, so thanks in advance for your testing !
