Currently, the default maximum CPU throttle for migration is
99(CPU_THROTTLE_PCT_MAX). This is too big and can make a remarkable
performance effect for the guest. We see a lot of packets latency
exceed 500ms when the CPU_THROTTLE_PCT_MAX reached. This patch set
adds a new qmp command to limit the CPU throttle.
Li Qiang (3):
migrate: replace the cpu throttle percentage max with a variable
migration: Add qmp command for migrate_set_max_cpu_throttle
hmp: add hmp for migrate_set_max_cpu_throttle
