3. Administration of the Red Hat Enterprise Virtualization Platform

This section provides a high level overview of the tasks and responsibilities of a system administrator for the Red Hat Enterprise Virtualization platform. The tasks are divided into two general groups:
  • Configuring a new logical data center is the most important task of the system administrator. Designing a new data center requires an understanding of capacity planning and definition of requirements. Typically this is determined by the solution architect, who provides the requirement to the system architect. Preparing to set up the virtualized environment is a significant part of the set up, and is usually part of the system administrator's role.
  • Maintaining the data center, including performing updates and monitoring usage and performance to keep the data center responsive to changing needs and loads.
The procedures to complete these tasks are described in detail in later sections of this guide.
It is assumed that you have already read the material in Red Hat Enterprise Virtualization 3.0 Installation Guide.

3.1. Maintaining the Red Hat Enterprise Virtualization Platform

This section describes how to maintain a Red Hat Enterprise Virtualization platform.
The administrator's tasks include:
  • Managing physical and virtual resources such as hosts and virtual machines. This includes upgrading or adding hosts, importing domains, and converting virtual machines created on foreign hypervisors, and the maintenance of pools of desktops.
  • Monitoring the overall system resources for potential problems such as extreme load on one of the hosts, insufficient memory or disk space, and taking any necessary actions (such as migrating virtual machines to other hosts to lessen the load, freeing resources, for example, by shutting down machines).
  • Responding to the new requirements of virtual machines (for example, upgrading the operating system for a set of virtual desktops or allocating more memory to a specific virtual server).
  • Managing customized object properties (Tags).
  • Managing searches saved as public bookmarks.
  • Managing user setup and access and setting user and administrator permission levels. This includes assigning or customizing roles to suit the needs of the enterprise.
  • Troubleshooting for specific users or virtual machines or overall system functionality.
  • Generating general and specific reports.
These tasks are described in detail in later sections of this guide.
