Using -device/device_add in combination with query-hotpluggable-cpus QMP command allows to hotplug CPUs at any not used possition and then safely migrate QEMU instance by specifying hotadded CPUs on target with help of -device CLI option like with any other device. Having been able to hotadd arbitrary CPUs and migrate also opens poosibility to hot-remove arbitrary CPUs, which will be a separate series on top of this one. Series depends on following not yet commited patchsets: 1: [PATCH v2 00/10] ACPI CPU hotplug refactoring to support unplug and more than 255 CPUs https://lists.gnu.org/archive/html/qemu-devel/2016-06/msg04671.html 2: [PATCH v2 0/6] cpus: make "-cpu cpux, features" global properties https://lists.gnu.org/archive/html/qemu-devel/2016-06/msg02579.html 3: [PATCH v2 00/10] globals: Clean up validation and error checking https://lists.gnu.org/archive/html/qemu-devel/2016-06/msg05662.html git tree for testing: https://github.com/imammedo/qemu.git dev_add_cpu_v1 for viewing: https://github.com/imammedo/qemu/commits/dev_add_cpu_v1 Igor Mammedov (11): target-i386: cpu: use uint32_t for X86CPU.apic_id pc: add x86_topo_ids_from_apicid() pc: extract CPU lookup into a separate function pc: cpu: consolidate apic-id validity checks in pc_cpu_pre_plug() target-i386: cpu: replace custom apic-id setter/getter with static property target-i386: add socket/core/thread properties to X86CPU pc: set APIC ID based on socket/core/thread ids if it's not been set yet pc: implement query-hotpluggable-cpus callback pc: register created initial and hotpluged CPUs in one place pc_cpu_plug() pc: delay setting number of boot CPUs to machine_done time pc: cpu: allow device_add to be used with x86 cpu hw/i386/pc.c | 170 +++++++++++++++++++++++++++++++++++---------- include/hw/i386/topology.h | 15 ++++ qmp-commands.hx | 15 ++++ target-i386/cpu.c | 64 +++-------------- target-i386/cpu.h | 8 ++- 5 files changed, 180 insertions(+), 92 deletions(-) -- 1.8.3.1
