  "message": "acpi-build: Set FORCE_APIC_CLUSTER_MODEL bit for FADT flags\n\nIf we start Windows 2008 R2 DataCenter with number of cpu less than 8,\nThe system will use APIC Flat Logical destination mode as default configuration,\nWhich has an upper limit of 8 CPUs.\n\nThe fault is that VM can not show all processors within Task Manager if\nwe hot-add cpus when the number of cpus in VM extends the limit of 8.\n\nIf we use cluster destination model, the problem will be solved.\n\nNote:\nThis flag was introduced later than ACPI v1.0 specification while QEMU\ngenerates v1.0 tables only, but...\n\nlinux kernel ignores this flag, so patch has no influence on it.\n\nTested with Win[XPsp3|Srv2003EE|Srv2008DC|Srv2008R2|Srv2012R2], there\nisn\u0027t BSODs and guests boot just fine. In cases guest doesn\u0027t support\ncpu-hotplug, cpu becomes visible after reboot and in case the guest\nsupports cpu-hotplug, it works as expected with this patch.\n\nCc: qemu-stable@nongnu.org\nSigned-off-by: huangzhichao \u003chuangzhichao@huawei.com\u003e\nSigned-off-by: zhanghailiang \u003czhang.zhanghailiang@huawei.com\u003e\nReviewed-by: Michael S.
