internal error: Unknown CPU model Skylake-Client-IBRS

解决办法：
3） Nova CPU 指令集迁移
a) nova 配置
cpu_model=none
cpu_mode=none
b) 修改/usr/lib/python2.7/site-packages/nova/conductor/task/live_migrae.py 106行，210行
106 #Add william ,delete check_compatible
107 #self._check_compatible_with_source_hypervisor(self.destination)

210    #Add william ,delete check_compatible
211    #self._check_compatible_with_source_hypervisor(host)

c) 修改/usr/lib/python2.7/site-packages/nova/virt/libvirt/driver.py 5478行
#Add william ,Compare CPU is del
#if not instance.vcpu_model or not instance.vcpu_model.model:

source_cpu_info = src_compute_info[‘cpu_info‘]

    #    self._compare_cpu(None, source_cpu_info)
    #else:
        #    self._compare_cpu(instance.vcpu_model, None)

Migration pre-check error: CPU doesn‘t have compat
