第 10 章 为实例配置 CPU 功能标记
您可以在不更改主机 Compute 节点上的设置并重新引导 Compute 节点的情况下，为实例启用或禁用 CPU 功能标记。通过配置应用到实例的标准 CPU 功能标记集合，这有助于在 Compute 节点之间实现实时迁移兼容性。您还有助于管理实例的性能和安全性，方法是禁用对带有特定 CPU 模型的实例的安全性或性能的标记，或者启用提供安全问题缓解的标记。

主机 Compute 节点的硬件和软件必须支持 CPU 模型和功能标记：
要检查主机支持的硬件，在 Compute 节点上输入以下命令：
$ cat /proc/cpuinfo要检查主机上支持的 CPU 型号，请在 Compute 节点上输入以下命令：
$ sudo podman exec -it nova_libvirt virsh cpu-models <arch>将
<arch> 替换为构架的名称，如x86_64。
