我目前正在努力寻找我的 ubuntu VM 不断崩溃的原因。新安装的 18.04.1 ubuntu 服务器仅安装了 plex 媒体服务器。主机是 PowerEdge T620，vSphere 报告了以下情况：CPU 已被客户操作系统禁用。关闭或重置虚拟机。
我在旧的 plex vm 上遇到过这个问题，这就是我启动新 vm 来消除这些崩溃的原因。但没有成功...
这是 kernel.log 的最后几行：

我还应该去哪里寻找呢？
这是唯一崩溃的虚拟机……
谢谢你的帮助！

答案1
这是影响 VMware ESXi 6.5 的已知问题，有三种方法可以解决该问题。我已将 vmxnet3.rev.30 = FALSE 参数添加到虚拟机。
