The document discusses installing and running Mesos DC/OS on openSUSE using Vagrant and VirtualBox. The author first installs openSUSE, VirtualBox, Vagrant, and attempts to install DC/OS with Vagrant but encounters issues with host-only networking that are resolved by manually configuring the IP address. Once networking is fixed, DC/OS can be successfully installed and accessed on Vagrant VMs running on openSUSE. The author concludes that while there were challenges, especially with networking, Mesos and DC/OS can be run on openSUSE using this method.
