偶尔能进图形安装界面，但是安装程序崩溃。

国内搜了一搜，没有找到合适的答案。

在问答社区找到了原因

Are you using virtual machines or a hypervisor? If yes so,you should update your hypervisor host to the latest version so it can support the kernel version.

cpuFreq stands for cpu frequency scaling which enables the operating
system to scale the cpu frequency up or down in order to save power.
I’m not sure why you’re getting this error since there may be many
possible reasons,but if you’re using a hypervisor host - such as ESXi
- and your OSes are working fine after the boot and you’re only getting this error whilst the boot time,you need to update your
Hypervisor host since it does not fully support the newly upgraded
kernel version.

If you’re getting the same error on the latest version of hypervisors,
or if you’re not using virtual machines and it’s happening on your
primary OS,you need to check if your hardware is working fine or not.
But this is not CentOS or RHEL problem.

看来，虚拟机管理程序不支持最新的内核，版本太旧了，是时候更新VMare12.0.1到12.5.5了。
