Disable CentOS Load Kernel Modules ipmi_si No such device error

After CentOS 8 boots up, following error appeared when starting systemd-modules-load.service in /var/log/messages

Mar  1 15:48:40 centos kernel: ipmi_si: IPMI System Interface driver
Mar  1 15:48:40 centos kernel: ipmi_si: Unable to find any System Interface(s)
Mar  1 15:48:40 centos systemd-modules-load[561]: Failed to insert 'ipmi_si': No such device

Reason

The module ipmi_si is designed for physical servers with a remote control interface - an IPMI, and the CentOS 8 is running in a VM.

Solution

Create /etc/modprobe.d/blacklist-ipmi.conf file with following lines,

blacklist ipmi_si
blacklist ipmi_devintf
blacklist ipmi_msghandler
blacklist ipmi_ssif
blacklist ipmi_watchdog
blacklist ipmi_poweroff
blacklist acpi_ipmi
blacklist ibmaem
blacklist ibmpex
