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:
The procedures to complete these tasks are described in detail in later sections of this 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.
