打开堆栈，试图启动实例：libvirtError：不支持的configuration：CPU规范不被pipe理程序支持

目前，我在AWS EC2服务器上运行Openstack以进行testing/学习，尤其是使用高频Intel Xeon E5-2670（Sandy Bridge）处理器的m3版本。

每当我启动一个实例，我在/var/log/nova/nova-compute.log中得到这个错误

libvirtError: unsupported configuration: CPU specification not supported by hypervisor 

错误是相当自我解释，我发现这些链接指向一个可能的解决scheme：

https://wiki.openstack.org/wiki/LibvirtXMLCPUModel

• SSD升级后EC2性能变差
• EC2实例初始化只有1/2检查，因此无法login到我的Linux服务器
• 任何方式来阻止IP地址主机头欺骗？
• 将新用户添加到AWS EC2 – 权限被拒绝（publickey）
• docker.io包报告仅在EC2上丢失

https://www.berrange.com/posts/2010/02/15/guest-cpu-model-configuration-in-libvirt-with-qemukvm/

我一直在尝试（受过教育的）反复试验，但到目前为止还没有取得成功，恐怕我错过了一些明显的东西。

我在正确的道路上？ 任何在AWS上运行Openstack的人都可以分享一些见解吗？
