Hi Frank,
For your question, What should I do if I want to setup IPMI on my centos host?
1. Make sure your host hardware has BMC provided, typically a server does, but a PC or laptop won't, 2. If so, use command "modprobe ipmi_si" or ipmi_devintf to load the kernel device driver for BMC If not, your host is not capable to setup IPMI becasue required hardware not exists
If loading kernel device successful, you won't see below error anymore when typing ipmitool in the bash Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory
Thank Ji Xiang

Hi all,
I am trying to load kernel module ipmi_si, while failed with error "No such device", truth is I can find file in ../kernel/drivers/char/ipmi/ipmi_si.ko. So why I can't load it?
Steps:
# ls -l /lib/modules/2.6.32-573.el6.x86_64/kernel/drivers/char/ipmi/ipmi_si.ko -rwxr--r--. 1 root root 93080 Jul 23 2015 /lib/modules/2.6.32-573.el6.x86_64/kernel/drivers/char/ipmi/ipmi_si.ko
# modprobe ipmi_si FATAL: Error inserting ipmi_si (/lib/modules/2.6.32-573.el6.x86_64/kernel/drivers/char/ipmi/ipmi_si.ko): No such device
# lsmod |grep ipmi ipmi_devintf 7729 0 ipmi_poweroff 8532 0 ipmi_watchdog 17874 0 ipmi_msghandler 38701 3 ipmi_devintf,ipmi_poweroff,ipmi_watchdog
# ipmitool
