Re: [libvirt] [RFC PATCH v2 00/12] qemu: add support to hot-plug/unplug cpu device

If you apply the folowing patchset in order [PATCH v3 0/7] cpu: add device_add foo-x86_64-cpu support https://lists.nongnu.org/archive/html/qemu-devel/2015-01/msg01552.html, [PATCH v2 0/5] Common unplug and unplug request cb for memory and CPU hot-unplug https://lists.nongnu.org/archive/html/qemu-devel/2015-01/msg03929.html and [PATCH v2 00/11] cpu: add i386 cpu hot remove support https://lists.nongnu.org/archive/html/qemu-devel/2015-01/msg01557.html, qemu can support hotplug and hot-unplug cpu device. So this patch series will make libvirt support hotplug and hot-unplug cpu device for qemu driver. This patch series add a new API to support cpu hot-plug/unplug, and leave the existing API by invoking qemu command 'cpu-add' as a legacy. This patch series realize cpu hot-plug/unplug by libvirt command 'attach-device' and 'detach-device', and invoke qemu command 'device_add' and 'device_del' to support this feature. v2: - update cpu device's definition, and cpu's apic_id is hidded to users. - add check for compatibility between host cpu and hot added cpu - add a capability for *-x86_64-cpu Zhu Guihua (12): domain_conf: add support for cpu device configuration in XML domain_conf: introduce cpu def helpers domain_conf: introduce cpu device hotplug helpers qemu_driver: implement cpu device hotplug on config level qemu_command: introduce a func for cpu device alias assignment domain_conf: allocate cpu's apic id dynamically qemu: add a capability for x86_64-cpu qemu: introduce qemuBuildCPUDeviceStr qemu: implement cpu device hotplug on live level qemu: implement cpu device hotunplug on live level qemu_monitor_json: sort JSON array of cpu info qemu_driver: detect threads corresponding to Vcpus docs/formatdomain.html.in | 28 ++++ docs/schemas/domaincommon.rng | 3 + src/conf/domain_conf.c | 189 +++++++++++++++++++++++++- src/conf/domain_conf.h | 33 +++++ src/libvirt_private.syms | 6 + src/qemu/qemu_capabilities.c | 3 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 120 +++++++++++++++++ src/qemu/qemu_command.h | 10 ++ src/qemu/qemu_driver.c | 299 ++++++++++++++++++++++++------------------ src/qemu/qemu_driver.h | 8 ++ src/qemu/qemu_hotplug.c | 140 ++++++++++++++++++++ src/qemu/qemu_hotplug.h | 12 ++ src/qemu/qemu_monitor_json.c | 31 ++++- src/util/virbitmap.c | 2 +- src/util/virbitmap.h | 2 + 16 files changed, 753 insertions(+), 134 deletions(-)
