[libvirt] [PATCHv2 0/3] reorder qemu cgroups operations
by Henning Schild 01 Mar '16

01 Mar '16

This is a much shorter series focusing on the key point, the second patch. The first patch is somehing that was found when looking at the code and is just a cosmetic change. The third patch just cleans up. They where both already ACKed. Patch 2 was also already ACKed but conflicted with another pending change. It should be reviewed in its new context. Note the new order with the "manual" affinity setting code. @Peter: qemuProcessInitCpuAffinity and qemuProcessSetupEmulator have a lot in in common. I guess there is potential for further simplification. The series is based on 92ec2e5e9b79b7df4d575040224bd606ab0b6dd8 with these two patches on top: http://www.redhat.com/archives/libvir-list/2016-February/msg01211.html Henning Schild (3): vircgroup: one central point for adding tasks to cgroups qemu_cgroup: put qemu right into emulator sub-cgroup qemu_cgroup: use virCgroupAddTask instead of virCgroupMoveTask src/libvirt_private.syms | 1 - src/qemu/qemu_process.c | 10 ++--- src/util/vircgroup.c | 105 +---------------------------------------------- src/util/vircgroup.h | 3 -- 4 files changed, 6 insertions(+), 113 deletions(-) -- 2.4.10

[libvirt] [RFC PATCH 0/2] ARM: add QMP command to query GIC version
by Peter Xu 01 Mar '16

01 Mar '16

For ARM platform, we still do not have any interface to query whether current QEMU/host support specific GIC version. This patchset is trying to add one QMP interface for that. By querying the GIC capability using the new interface, one should know exactly what GIC version(s) the platform will support. The capability bits will be decided by both QEMU and host kernel. The current patchset only provides interface for review. Its handler is a fake one which returns empty always. The command interface I am planning to add is something like this: -> { "execute": "query-gic-capability" } <- { "return": [ "gicv2", "gicv2-kvm", "gicv3-kvm" ] } Currently, all the possible supported GIC versions are: - gicv2: GIC version 2 without kernel IRQ chip - gicv2-kvm: GIC version 2 with kernel IRQ chip - gicv3: GIC version 3 without kernel IRQ chip (not supported) - gicv3-kvm: GIC version 3 with kernel IRQ chip Since "gicv3" is still not supported (to use GICv3, kernel irqchip support is required for now, which corresponds to "gicv3-kvm"), currently the maximum superset of the result should be: ["gicv2", "gicv2-kvm", "gicv3-kvm"] Please help review whether the interface suits our need, also please point out any error I have made. One question: how should I make this command "ARM only"? I see that in qmp-commands.hx, I can use something like "#if defined TARGET_ARM" to block out ARM specified commands, however how should I do the similiar thing in qapi-schema.json? Thanks!

[libvirt] setlocale problems / "initialization failed" in Rawhide
by Richard W.M. Jones 29 Feb '16

29 Feb '16

https://bugzilla.redhat.com/show_bug.cgi?id=1312688 When you upgrade from F23 to current Rawhide, you don't get any "language pack" installed. It turns out this breaks many things including libvirtd which no longer starts up: $ ./daemon/libvirtd --help /home/rjones/d/libvirt/daemon/.libs/lt-libvirtd: initialization failed Simply installing glibc-langpack-en is sufficient to fix this, but I was wondering if we should try to make libvirt work anyway. The failure comes from setlocale (LC_ALL, "") returning NULL. The attached test program prints: $ ./test setlocale failed, errno=No such file or directory Also attached is the strace output so you can see what files it is looking for. Seems like solutions to this include: - Make libvirt in Fedora depend on glibc-langpack-en. - Ignore the return value from setlocale. It seems unlikely that we really care if setlocale fails. I'm not even sure what it does. Note that virsh already ignores setlocale: if (!setlocale(LC_ALL, "")) { perror("setlocale"); /* failure to setup locale is not fatal */ } Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com virt-top is 'top' for virtual machines.

[libvirt] ANNOUNCE: Oz 0.15.0 release
by Chris Lalancette 29 Feb '16

29 Feb '16

All, I'm pleased to announce release 0.15.0 of Oz. Oz is a program for doing automated installation of guest operating systems with limited input from the user. Release 0.15.0 is a bugfix and feature release for Oz. Some of the highlights between Oz 0.14.0 and 0.15.0 are: * Make sure openssh-clients is included in CentOS builds * Add support for Fedora-23 * Add customization support for Debian * Use the ssh -i option to avoid "Too many authentication failures" with many ssh keys * Support "rawhide" as a Fedora version * Add in Ubuntu 15.10 support * Add in OpenSUSE 13.2 support * Improve Oz's free port selection A tarball and zipfile of this release is available on the Github releases page: https://github.com/clalancette/oz/releases . Packages for Fedora-22, Fedora-23, and EPEL-7 have been built in Koji and will eventually make their way to stable. Instructions on how to get and use Oz are available at http://github.com/clalancette/oz/wiki . If you have questions or comments about Oz, please feel free to contact me at clalancette at gmail.com, or open up an issue on the github page: http://github.com/clalancette/oz/issues . Thanks to everyone who contributed to this release through bug reports, patches, and suggestions for improvement. Chris Lalancette
