[libvirt] [PATCH] Fix build w/o cgroups
by Roman Bogorodskiy 04 Aug '13

04 Aug '13

Build without cgroups support started to fail again recently.

[libvirt] [PATCH 0/9] qemu: Support qemu-system-arm vexpress-a9
by Cole Robinson 03 Aug '13

03 Aug '13

This series adds the bits needed to kick of a qemu-system-arm -machine vexpress-a9 guest. Patches 1 and 8 are isolated bug fixes Patches 2-5 and 7 are mostly about fixing CLI generation. Unfortunately qemu ARM boards don't quite work like x86 where we can mix and match devices, so -device is out of the picture, and the boards depend on old CLI infrastrucure like -net nic and -serial. Patch 6 adds disk bus=sd, which is often the only way to specify storage for ARM boards. Patch 9 adds virtio-mmio address support, which enables virtio for vexpress-a9. Cole Robinson (9): qemu_command: Drop incorrect ATTRIBUTE_UNUSED annotation domain_conf: Set QEMU ARM default USB model to 'none' domain_conf: Don't add default memballoon device on ARM qemu: Fix adding specifying char devs for ARM qemu: Don't try to allocate PCI addresses for ARM domain_conf: Add disk bus=sd, wire it up for qemu qemu: Fix networking for ARM guests qemu: Only setup vhost if virtType == "kvm" qemu: Support virtio-mmio transport for virtio on ARM docs/formatdomain.html.in | 3 +- docs/schemas/domaincommon.rng | 20 ++++ src/conf/domain_conf.c | 72 +++++++++--- src/conf/domain_conf.h | 2 + src/qemu/qemu_capabilities.c | 22 ++++ src/qemu/qemu_capabilities.h | 5 + src/qemu/qemu_command.c | 126 +++++++++++++++++---- src/qemu/qemu_domain.c | 20 +++- src/qemu/qemu_process.c | 37 +++--- .../qemuxml2argv-arm-vexpressa9-basic.args | 1 + .../qemuxml2argv-arm-vexpressa9-basic.xml | 34 ++++++ .../qemuxml2argv-arm-vexpressa9-nodevs.args | 1 + .../qemuxml2argv-arm-vexpressa9-nodevs.xml | 26 +++++ .../qemuxml2argv-arm-vexpressa9-virtio.args | 1 + .../qemuxml2argv-arm-vexpressa9-virtio.xml | 45 ++++++++ tests/qemuxml2argvtest.c | 10 ++ tests/testutilsqemu.c | 32 ++++++ 17 files changed, 397 insertions(+), 60 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-arm-vexpressa9-basic.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-arm-vexpressa9-basic.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-arm-vexpressa9-nodevs.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-arm-vexpressa9-nodevs.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-arm-vexpressa9-virtio.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-arm-vexpressa9-virtio.xml -- 1.8.3.1

[libvirt] infinite loop while restarting libvirt after LXC creation

Hi, I'm using OpenStack grizzly on Ubuntu 12.04 to create LXC containers.
