在 CentOS7 主機上安裝 CentOS7 來賓時出現核心崩潰
我正在嘗試在 CentOS 7 KVM 主機上安裝 CentOS 7 來賓作為來賓，但不斷出現核心恐慌，而且似乎每次都發生在完全相同的位置。我什至嘗試過安裝 CentOS 6 來賓，但也讓核心恐慌。
已經有五個來賓（所有 CentOS 6）在主機上執行，儘管它們都是從另一台主機移走的。我已經用最新的更新更新了主機，只安裝了標準的 repos 和軟體包，但仍然沒有運氣。
希望有人能看到我做錯了什麼或可能導致核心恐慌的原因。
處理器是 Intel Core i3-4130，主機板是 Gigabyte Z97P-D3，16GB RAM。

最後在 CentOS 官方論壇中通過drk的提示解決了這個問題，問題出在 CPU 設置上，只需刪除設置並使用預設 CPU 設置就可以了。這最終對我有用：
