RHEV Manager 2.1 Installtion Prerequisite

RHEV Manager 2.1 Installation Prerequisite

  If you are new to RHEV , please read the the below article of RHEV Overview to get a good idea about how various pieces of RHEV Works .

This section describes the basic hardware and software prerequisites required for installing the Red Hat Enterprise Virtualization platform version 2.1 .

Ensure that the listed requirements are ready before attempting installation.

Red Hat Enterprise Virtualization Manager
Hardware & Software requirements

One Physical or Virtual server(xen/kvm/vmware/hyper-v) to act as the Red Hat Enterprise Virtualization Manager Manager, with:

Minimum 1 GB of memory.

Minimum 20 GB of local disk space.

Microsoft Windows Server 2003 (or R2) 32-bit edition, with:

Windows Server 2003 Service Pack 2

Valid Microsoft Windows Server 2003 product key

The following Windows components: 

  Microsoft .NET Framework 3.5 Service Pack 1.
 Available from:

  Microsoft .NET Framework 3.5 Family Update for Windows Server 2003.
Filename: NDP35SP1-KB958484-x86.exe

  Windows Power Shell 1.0
Filename: WindowsServer2003-KB926139-v2-x86-ENU.exe
  Recommended utilities for transferring files between RHEV Manager and RHEV Hypervisor:   
 WinSCP: open source Secure Copy (SCP) client for Windows.  
 PuTTY: open source Secure Shell (SSH) client for Windows and Unix platforms. 

Red Hat Enterprise Virtualization Hypervisor 
Hardware & Software requirements

One or more physical servers to act as the Red Hat Enterprise Virtualization Manager Hypervisors or Red Hat Enterprise Linux Hosts, each with:

Hardware virtualization support:
AMD system with AMD-V enabled in the BIOS and AMD64 CPU extension; or
Intel system with Intel VT enabled in the BIOS and Intel 64 CPU extensions.

Minimum 512MB of RAM for Hypervisor or Host

Minimum 512MB of additional RAM for each virtual machine. The amount of RAM allocated to each virtual machine is dependent on the guest operating system.

Minimum 750MB (recommended 5GB ATM) storage for installation of the Hypervisor on hard disk drive, plus additional storage for swap.

Ensure that all Hypervisor or host servers to be used within a single cluster(its not an application cluster , it means you can create an n number of cluster in a Data centre of RHEVM , so that virtual machines will only migrate between those hosts in the same cluster ) inside the RHEV have the same CPU type .

Note: You can't mix Intel and AMD  hosts in the same cluster .

Red Hat Enterprise Virtualization Manager Hypervisor installation software; and/or

A Red Hat Enterprise Linux 5.4 AMD64/Intel 64 system.

Note: You can use mix RHEL Host or RHEV-H(100 MB) in the same cluster .

Storage Requirements 

Server to provide storage for virtual machine and ISO images .

Storage networking can be implemented using Network File System (NFS), Internet Small Computer System Interface (iSCSI) or Fibre Channel Protocol (FCP).

Note: RHEV uses Data Domain for storing virtual machines that can be either of NFS or ISCSI or FCP Back end ,  and ISO Domain for storing ISO Dumps of various operating system to spin up new virtual machines and various third party software's   that  supports only nfs as a  Back end storage .

At least one network controller with a minimum bandwidth of 100 Mbps.(Recommended 1GB )

Accessing RHEV Manager from Remote Clients 

A client with Windows XP and .NET Framework 3.1 with Service Pack 1 is required to access the  web-based administration portal. The web-based administration portal can be used as an alternative to the administration portal available on the RHEV Manager server.

Note: ATM the RHEVM Administration Portal is only available on windows platform .
