This talk shows how to setup a virtual infrastructure using OpenNebula as cloud management platform, SaltStack for configuration management and Foreman for bare-metal/ virtual host provisioning. You will see how to combine OpenNebula with bare-metal deployment on standard server hardware using non-shared storage in an environment without physical access to the hardware and no existing base infrastructure like DNS, NTP, DHCP, VPN or other. The infrastructure installation has been done automatically using public code and free Open Source software.
