The "Reboot your system to update the kernel" after update and restart the server for CloudLinux OS 8.7

Issue

The server was updated to the CloudLinux OS 8.7 and kernel 4.18.0-425.3.1.lve.1.el8.x86_64, and shows the "Reboot your system to update the kernel" error after that.

Environment

• CloudLinux 8.7
• Kernel 4.18.0-425.3.1.lve.1.el8.x86_64

Solution

1. Update the kmod-lve package to the latest version:

yum update kmod-lve

2. Try to load the kmodlve module using modprobe:

modprobe kmodlve

3. The empty output is fine, you can check that the module is loaded:

lsmod | grep kmodlve

4. If the modprobe kmodlve command shows errors, try to reinstall the packages below:

yum reinstall kernel kmod-lve

5. Try to load the module using the modprobe again.

If the issue still persists, you most likely faced the KMODLVE-575 bug. As a workaround, you can reboot your server with the previous kernel versions.
