Reboot your system to update the kernel message in WHM (CloudLinux OS 8)

Issue

You see the "Reboot your system to update the kernel" message in WHM, but your running kernel is already CloudLinux one (has LVE in the name).

Environment

• CloudLinux OS 8

Solution

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

yum update kmod-lve

2. Reboot the server:

reboot

3. If it doesn't help, try to load the module manually:

modprobe kmodlve

Most likely, it will show an error.

4. If there is the following output:

modprobe kmodlve
modprobe: ERROR: could not insert 'kmodlve': Cannot allocate memory

5. In your /etc/default/grub file, check this line:

GRUB_CMDLINE_LINUX_DEFAULT="${GRUB_CMDLINE_LINUX_DEFAULT} rootflags=uquota,pquota systemd.unified_cgroup_hierarchy=1 psi=1"

and remove systemd.unified_cgroup_hierarchy=1 from it.

6. Apply changes in Grub2 configuration:

grub2-mkconfig -o /etc/grub2.cfg

In the case of UEFI:

grub2-mkconfig -o /etc/grub2-efi.cfg

7. Reboot the server:

reboot

Cause

The kmod-lve kernel module is not loaded. You can verify with:

lsmod | grep lve
