Environment: macOS Big Sur, VirtualBox6.1, CentOs8.
CPU always run to 100% even if CentOs guest is idle
from search, I known the time interrupt frequency is 10 times higher than other linux.
Add parameter of ‘divider=10’ to grub.conf, then reboot system can cool CPU down. But each time, I awake the computer from sleep, the problem happen again. I have to reboot the CentOs to deal with this.
This is a terrible experience.
To my guess, the awake process of the Guest CentOs is different from the boot process. And the parameter ‘divider=10’ failed to function in awake process.
But I don’t know the detail, and I can not fix the problem.
