This change is supposed to improve the documentation that currently exists, without adding much new content. Details: * Reorganized the main page into a common overview section, a section for users of the driver, and a section for contributors, and a section with links for quick access. * Separated between the `README.rst` file and the introductory text on the main page, because the `README.rst` file stands on its own when shown on the Github code page, while the introductory text is part of the larger documentation. As a result, removed the `doc/source/readme.rst` file. * Added an empty chapter for the topology to the overview section of the main page, instead of referencing the readme file. * Cleaned up headings and file names somewhat. * Added link targets to any major headings. * Adapted the contributions page to the project, and added links for the Git repo and the Gerrit review page.

Welcome to nova-dpm's documentation!
On IBM z Systems and IBM LinuxOne machines, certain workloads run better in a partition of the firmware-based PR/SM (Processor Resource/System Manager) hypervisor, than in a virtual machine of a software hypervisor such as KVM or z/VM.
This project provides a Nova virtualization driver for the PR/SM hypervisor of IBM z Systems and IBM LinuxOne machines that are in the DPM (Dynamic Partition Manager) administrative mode.
The DPM mode enables dynamic capabilities of the firmware-based PR/SM hypervisor that are usually known from software-based hypervisors, such as creation, deletion and modification of partitions (i.e. virtual machines) and virtual devices within these partitions, and dynamic assignment of these virtual devices to physical I/O adapters.
The z/VM and KVM hypervisors on z Systems and LinuxONE machines are supported by separate Nova virtualization drivers:
- KVM is supported by the standard libvirt/KVM driver in the openstack/nova project.
- z/VM is supported by the z/VM driver in the openstack/nova-zvm-virt-driver project.
