The document outlines the prerequisites for installing Red Hat Enterprise Virtualization including the minimum and recommended system requirements for the manager and hypervisor components. It describes that the manager provides a graphical interface to manage physical and virtual resources from Red Hat Enterprise Linux servers acting as hypervisor hosts. Storage can be provided by NFS, iSCSI or FCP and networking requirements include static IP addresses, DNS and DHCP.

- 1. Red Hat Enterprise Virtualization Prerequisites The Red Hat Enterprise Virtualization platform is a virtualization management solution providing fully integrated management for virtual machines. The Red Hat Enterprise Virtualization platform comprises various components which work seamlessly together as represented in the following diagram : Figure 1. Overview of Red Hat Enterprise Virtualization Components Prerequisites The following requirements are typical for small to medium-sized installations. Note that the exact requirements of the setup depend on the specific installation, sizing and load. Please use the following requirements as guidelines:
- 2. Red Hat Enterprise Virtualization Manager • Minimum - Dual core server with 4 GB RAM, with 25 GB free disk space and 1 Gbps network interface. • Recommended - Dual Sockets/Quad core server with 16 GB RAM, 50 GB free disk space on multiple disk spindles and 1 Gbps network interface. • A valid Red Hat Network subscription to the following channels : • The Red Hat Enterprise Virtualization Manager (v.3 x86_64) channel, also referred to as rhel-x86_64-server-6-rhevm-3, which provides Red Hat Enterprise Virtualization Manager. • The JBoss Application Platform (v 5 in rpm) channel, also referred to as jbappplatform-5-x86_64-server-6-rpm, which provides the supported release of the application platform on which the manager runs. • The RHEL Server Supplementary (v. 6 64-bit x86_64) channel, also referred to as rhel-x86_64-server-supplementary-6, which provides the supported version of the Java Runtime Environment (JRE). Red Hat Enterprise Virtualization Hypervisor • Minimum - Dual core server, 10 GB RAM and 10 GB Storage, 1 Gbps network interface. • Recommended - Dual socket server, 16 GB RAM and 50 GB storage, two 1 Gbps network interfaces. • Valid Red Hat Network subscriptions for each each Red Hat Enterprise Virtualization Hypervisor host : • The Red Hat Enterprise Virtualization Hypervisor (v.6 x86-64) channel, also referred to as rhel-x86_64-server-6-rhevh. Storage and Networking • At least one of the supported storage types (NFS, iSCSI and FCP). • For NFS storage, a valid IP address and export path is required. • For iSCSI storage, a valid IP address and target information is required.
- 3. • Static IP addresses for the Red Hat Enterprise Virtualization Manager server and for each host server. • DNS service which can resolve (forward and reverse) all the IP addresses. • An existing DHCP server which can allocate network addresses for the virtual machines. Virtual Machines • Installation images for creating virtual machines, depending on which operating system you wish to use. • Microsoft Windows XP, 7, 2003 or 2008. • Red Hat Enterprise Linux 3, 4, 5 or 6. • Valid licenses or subscription entitlements for each operating system. The Red Hat Enterprise Virtualization platform consists of at least one Manager and one or more hosts. • Red Hat Enterprise Virtualization Manager provides a graphical user interface to manage the physical and logical resources of the Red Hat Enterprise Virtualization infrastructure. The Manager is installed on a Red Hat Enterprise Linux 6 server, and accessed from a Windows client running Internet Explorer. • Red Hat Enterprise Virtualization Hypervisor runs virtual machines. A physical server running Red Hat Enterprise Linux can also be configured as a host for virtual machines on the Red Hat Enterprise Virtualization platform. The Manager is the control center of the Red Hat Enterprise Virtualization environment. It allows you to define hosts, configure data centers, add storage, define networks, create virtual machines, manage user permissions and use templates from one central location. The Red Hat Enterprise Virtualization Manager must be installed on a server running Red Hat Enterprise Linux 6, with minimum 4 GB RAM, 25 GB free disk space and 1 Gbps network interface.
