openstack 虚机迁移 Unacceptable CPU info: CPU doesn't have compatibility

问题：

Unacceptable CPU info: CPU doesn't have compatibility

解决：

vim /usr/lib/python2.7/site-packages/nova/virt/libvirt/driver.py

函数：check_can_live_migrate_destination

屏蔽代码，避免CPU校验：

# Compare CPU
"""
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, instance)
else:
self._compare_cpu(instance.vcpu_model, None, instance)
"""
