From: XuYandong <xuyando...@huawei.com>
After vcpu1 thread exiting, vcpu0 thread (received notification) is still
waiting for
holding qemu_global_mutex in cpu_remove_sync, at this moment, vcpu1 is still in
global cpus list.
If main thread grab qemu_global_mutex in order to handle qmp command "info
cpus",
qmp_query_cpus visit unpluged vcpu1 will lead qemu process to exit.
