我已经将我的英特尔 i5 替换为 amd ryzen 7。现在我的 Windows 10 VM（libvirt/qemu）无法启动，它只是显示“准备自动修复”然后重新启动。
我也无法从救援 iso 启动。我有 EFI shell 访问权限，并且可以通过环回访问文件系统。我怎样才能让我的系统再次正确启动？

答案1
我可以通过将 CPU 从 切换到host-model来进行启动qemu-64。
性能似乎不错，所以我会保持这种状态，除非我找到一种启动方法host-model。
答案2
使用host-passthrough而不是host-model或qemu-64。如果host-passthrough下拉列表中不存在，则手动输入并重试。
host-model尝试匹配 qemu 中现有的 CPU 型号。host-passthrough按原样传递主机的 CPU。
