IPMI simulator

installation and configuration

This document describes about installation and configuration of  IPMI simulator.
We need:  qemu-kvm, OpenIPMI, OpenIPMI-tools
1) Install the qemu-kvm. We need the qemu, which have the IPMI pacthes.
   Use the source https://github.com/cminyard/qemu/tree/stable-2.2-ipmi
   ./configure, make and make install
   
2) Download the OpenIPMI libraries, from http://sourceforge.net/projects/openipmi/
   Follow the process documented in lanserv/README.vm
      ./configure --prefix=/opt/openipmi/usr --sysconfdir=/opt/openipmi/etc \
            --with-perlinstall=/opt/openipmi/usr/lib/perl \
            --with-pythoninstall=/opt/openipmi/usr/lib/python
      make and make install.
      
If you got the following errors while compiling: 
1)/usr/bin/ld: cannot find -lOpenIPMIutils
export CC="gcc -lrt" and reconfigure.

3) Configure the IPMI siulator:

Create a qemu disk to use:
qemu-img create -f qcow2 -o size=1G /opt/KVM/disk1.qcow2
We need kernel images, download one from : wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-i386-kernel

 edit the  /opt/openipmi/etc/ipmi/lan.conf
 change the startcmd, use the qemu compiled.
 /usr/local/bin/qemu-system-x86_64 --enable-kvm -drive file=/opt/KVM/Test4sda -nographic -net nic,model=e1000,macaddr=52:54:00:12:34:59 -net user,hostfwd=tcp::5556-10.0.2.15:22 -chardev socket,id=ipmi0,host=localhost,port=9011,reconnect=10 -device isa-ipmi,chardev=ipmi0,interface=bt,irq=5 -serial mon:tcp::9012,server,telnet,nowait

/usr/local/bin/qemu-system-x86_64 --enable-kvm -drive file=/opt/KVM/disk1.qcow2,format=qcow2 -nographic -net nic,model=e1000,macaddr=52:54:00:12:34:59 -net user,hostfwd=tcp::5555-10.0.2.15:22 -chardev socket,id=ipmi0,host=localhost,port=9002,reconnect=10 -device isa-ipmi,chardev=ipmi0,interface=bt,irq=5 -serial mon:tcp::9003,server,telnet,nowait -kernel /opt/cirros-0.3.4-i386-kernel --append 'root=/dev/hda console=ttyS0,115200'
   
Serial console is configured to /dev/ttyUSB0 in the lan.conf file, Find if your serial console is configured as such (or) change.
I changed my serial console as 
sol "/dev/ttyS0" 38400 history=4000 historyfru=10

4) Run IPMI_SIM 
/opt/openipmi/usr/bin/ipmi_sim

5) Connect to the simulator using ipmitool as below:
 ipmitool -I lanplus -H localhost -p 9011 -U cirros power status
 
 

donghwicha, I ran into same issue and managed to fix it by changing startcmd row to this:
startcmd "/usr/local/bin/qemu-system-x86_64 --enable-kvm -nographic -net nic,model=e1000,macaddr=52:54:00:12:34:59 -chardev socket,id=ipmi0,host=localhost,port=9002,reconnect=10 -device ipmi-bmc-extern,id=bmc0,chardev=ipmi0 -device isa-ipmi-bt,bmc=bmc0 -serial mon:tcp::9003,server,telnet,nowait -kernel /usr/src/cirros-0.3.4-i386-kernel --append 'root=/dev/sda console=ttyS0,115200'"
Right - no disk needed and no port forwarding even!

Also connect with ipmitool should be made to UDP port 9001 and not TCP 9011:
ipmitool -I lan -H 127.0.0.1 -p 9001 -U admin -P test power status

One more thing: ipmi sim gave me error about file absence every second:
Error getting sensor value (30,0,1): No such file or directory, Unable to open sensor file
So I opened /opt/openipmi/etc/ipmi/ipmisim1.emu file and replaced
sensor_add 0x30 0 1 0x01 0x01 poll 1000 file "/tmp/file1.ipm"
with
sensor_add 0x30 0 1 35 0x6f event-only
and error is gone now.

Spent few hours fixing problems after using this howto. Hope this will help someone.
