我正在尝试在 CentOS 7 KVM 主机上安装 CentOS 7 客户机，但一直出现内核恐慌，而且似乎每次都发生在完全相同的位置。我甚至尝试安装 CentOS 6 客户机，但同样出现内核恐慌。
主机上已经有 5 个客户机（全部为 CentOS 6）在运行，尽管它们都是从另一台主机移过来的。我已经用最新更新更新了主机，只安装了标准存储库和软件包，但仍然没有成功。
希望有人能够知道我做错了什么或者是什么导致了内核恐慌。
处理器是英特尔酷睿 i3-4130，主板是技嘉 Z97P-D3，16GB RAM。

最后通过以下提示解决了这个问题德克在官方 CentOS 论坛中，问题出在 CPU 设置上，只需删除该设置并使用默认 CPU 设置即可解决问题。以下是我最终有效的方法：
