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 在2016年5月25日 19:34, Frank Yu<flyxiaoyu@xxxxxxxxx>写道: 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?
