Installing Red Hat Enterprise Linux in VMware-workstation.

This section covers installing a fully virtualized Red Hat Enterprise Linux 5 guest.  the steps are interchangeable and different steps are noted.

Procedure : Creating a fully virtualized Red Hat Enterprise Linux 5 guest with virt-manager

1.Start the new virtual machine wizard

Pressing the New button starts the virtual machine creation wizard.

Press Next to continue.

2.Name the virtual machine

Provide a name for your virtualized guest. Punctuation and whitespace characters are not permitted in versions before Red Hat Enterprise Linux 5.5. Red Hat Enterprise Linux 5.5 adds support for ‘_‘, ‘.‘ and ‘‘ characters.

Press Next to continue.

3.Choose a virtualization method

Choose the virtualization method for the virtualized guest. Note you can only select an installed virtualization method.

Press Next to continue.

4.Select the installation method

Red Hat Enterprise Linux can be installed using one of the following methods:

  • local install media, either an ISO image or physical optical media.
  • Select Network install tree if you have the installation tree for Red Hat Enterprise Linux hosted somewhere on your network via HTTP, FTP or NFS.
  • PXE can be used if you have a PXE server configured for booting Red Hat Enterprise Linux installation media. Configuring a sever to PXE boot a Red Hat Enterprise Linux installation is not covered by this guide. However, most of the installation steps are the same after the media boots.

Set OS Type to Linux and OS Variant to Red Hat Enterprise Linux 5 as shown in the screenshot.

Press Next to continue.

5.Locate installation media

Select ISO image location or CD-ROM or DVD device. This example uses an ISO file image of the Red Hat Enterprise Linux installation DVD.

  1. Press the Browse button.
  2. Search to the location of the ISO file and select the ISO image. Press Open to confirm your selection.
  3. The file is selected and ready to install.

Press Next to continue.

6.Storage setup

Assign a physical storage device (Block device) or a file-based image (File). File-based images must be stored in the /var/lib/libvirt/images/ directory. Assign sufficient space for your virtualized guest and any applications the guest requires.

Press Next to continue.

7.Network setup

Select either Virtual network or Shared physical device.

The virtual network option uses Network Address Translation (NAT) to share the default network device with the virtualized guest. Use the virtual network option for wireless networks.

The shared physical device option uses a network bond to give the virtualized guest full access to a network device.

Press Next to continue.

8.Memory and CPU allocation

The Memory and CPU Allocation window displays. Choose appropriate values for the virtualized CPUs and RAM allocation. These values affect the host’s and guest’s performance.

Virtualized guests require sufficient physical memory (RAM) to run efficiently and effectively. Choose a memory value which suits your guest operating system and application requirements. Remember, guests use physical RAM. Running too many guests or leaving insufficient memory for the host system results in significant usage of virtual memory and swapping. Virtual memory is significantly slower which causes degraded system performance and responsiveness. Ensure you allocate sufficient memory for all guests and the host to operate effectively.

Assign sufficient virtual CPUs for the virtualized guest. If the guest runs a multithreaded application, assign the number of virtualized CPUs the guest will require to run efficiently. Do not assign more virtual CPUs than there are physical processors (or hyper-threads) available on the host system. It is possible to over allocate virtual processors, however, over allocating has a significant, negative effect on guest and host performance due to processor context switching overheads.

Press Next to continue.

9.Verify and start guest installation

Verify the configuration.

Press Finish to start the guest installation procedure.

10.Installing Red Hat Enterprise Linux

Complete the Red Hat Enterprise Linux 5 installation sequence.

A fully virtualized Red Hat Enterprise Linux 5 Guest is now installed.
