4.4. Preparing a RHEV Hypervisor from a CD-ROM or DVD

RHEV Hypervisors can be installed with a CD-ROM or DVD.

4.4.1. Making a bootable RHEV Hypervisor CD-ROM

Burn the RHEV 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. 
    # rpm -q cdrecord
cdrecord-2.01-10.7.el5
    Copy to Clipboard Toggle word wrap
    If the package version is in the output, as seen above, the package is available.
    If it is not present, install cdrecord: 
    # yum install cdrecord
    Copy to Clipboard Toggle word wrap
  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/
    Copy to Clipboard Toggle word wrap
    This example uses the first CD-RW (/dev/cdrw) device available and the default RHEV Hypervisor image location, /usr/share/rhev-hypervisor/rhev-hypervisor.iso. 
    # cdrecord dev=/dev/cdrw /usr/share/rhev-hypervisor/rhev-hypervisor.iso
    Copy to Clipboard Toggle word wrap
If no errors occurred, the RHEV 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 RHEV 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.

4.4.2. Booting a RHEV Hypervisor CD-ROM

For many systems, the default BIOS configuration boots from CD-ROM first. If booting from CD-ROM is disabled or is not the first boot device refer to Section 4.1.1, “BIOS settings and boot process troubleshooting” and your manufacturers manuals for more information.
To boot from CD-ROM, insert the RHEV Hypervisor CD-ROM and turn the computer on.
The RHEV Hypervisor should start to boot. If the RHEV Hypervisor does not start to boot your BIOS may not be configured to boot from CD-ROM first or booting from CD-ROM may be disabled.
If the Hypervisor is running, you must now initialize the local storage device. Refer to Section 5.1.1, “Booting the Hypervisor for installation” for details.
