MySQL mariadb run a test container on your machine
1) Pull docker image
$ docker pull mysql:5.7
2) Generate mysql random password for rot user.
$ export MYSQL_ROOT_PASSWORD=$(cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 32 | sed 1q)
3) create the container.
$ docker run -d --name mysql -p 3306:3306 --env MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD} docker.io/mysql:5.7

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 \
