linux - Error "no valid rapl domains found in package 0" when boot ubuntu 16.04 installed in virtualbox

Question

I have installed the Ubuntu in virtualbox for months. After I upgrade the Linux kernal, I cannot boot Ubuntu with normal mode. But it can success boot in recovery mode I occurred some error:

1. floppy0: no floppy controllers found. => this will let me wait a few minutes, and it will go through.

2. intel_rapl: no valid rapl domains found in package 0 =>the boot process stuck at this error

I don't know whether it's a problem whit kernal 4.72 or not.

Linux kernal: 4.72 lowlatency amd64 virtualbox version: 5.14 physic cpu: x86_64

Answer 1

I solved the problem by myself.

Below is my method:

1.Enter recovery mode.

2.Install generic version kernel

3.Purge all of the lowlatency kernels

But I still don't know why virtualbox can't run with lowlatency version kernel.

And the error (or normal boot process),"intel_rapl: no vaild rapl domains found in package 0", is still showed when boot, but it dosen't let the boot process stop.
