⁠1.3.2. Preparing Optical Hypervisor Installation Media

Summary
Burn the Hypervisor image to a CD with the wodim command. The wodim command is part of the wodim package.
⁠

Procedure 1.3. Preparing Optical Hypervisor Installation Media

  1. Verify that the wodim package is installed on the system.
    ⁠

    Example 1.4. Verify Installation of wodim Package

    # rpm -q wodim
wodim-1.1.9-11.el6.x86_64
    If the package version is in the output the package is available.
    If nothing is listed, install wodim: 
    # yum install wodim
  2. Insert a blank CD or DVD into your CD or DVD writer.
  3. Record the ISO file to the disc. The wodim command uses the following: 
    wodim dev=device image.iso
    This example uses the first CD-RW (/dev/cdrw) device available and the default hypervisor image location, /usr/share/rhev-hypervisor/rhev-hypervisor.iso.
    ⁠

    Example 1.5. Use of wodim Command

    # wodim dev=/dev/cdrw /usr/share/rhev-hypervisor/rhev-hypervisor.iso
Result
If no errors occurred, the Hypervisor is ready to boot. Errors sometimes occur during the recording process due to errors on the media itself. If this occurs insert another writable disk and repeat the command above.
The Hypervisor uses a program (isomd5sum) to verify the integrity of the installation media every time the Hypervisor is booted. If media errors are reported in the boot sequence you have a bad CD. Follow the procedure above to create a new CD or DVD.
