3.4. Preparing a Hypervisor from a CD-ROM or DVD

It is possible to install the Hypervisor with a CD-ROM or DVD.

3.4.1. Making a Hypervisor CD-ROM Boot Disk

Burn the Hypervisor image to a CD-ROM with the cdrecord command. The cdrecord command is part of the cdrecord package which is installed on Red Hat Enterprise Linux by default.
  1. Verify that the cdrecord package is installed on the system.
    Example 3.7. Verify Installation of cdrecord Package
    # rpm -q cdrecord
cdrecord-2.01-10.7.el5

    If the package version is in the output the package is available.
    If it is not listed, install cdrecord: 
    # yum install cdrecord
  2. Insert a blank CD-ROM or DVD into your CD or DVD writer.
  3. Record the ISO file to the disc. The cdrecord command uses the following: 
    cdrecord dev=device /iso/file/path/
    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 3.8. Use of cdrecord Command
    # cdrecord dev=/dev/cdrw /usr/share/rhev-hypervisor/rhev-hypervisor.iso

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-ROM. Follow the procedure above to create a new CD-ROM or DVD.
