Virtual machine start fails due to having the wrong boot order in RHEV environments

When creating a virtual machine, you can specify the boot order. If a virtual machine has the following boot order, the virtual machine start fails as it is not able to find the CD-ROM:

If VCS initiated the virtual machine start, any associated KVMGuest resources also fail. This issue is due to RHEV behavior.

If this issue occurs, manually edit the boot order and remove the CD-ROM from the boot sequence. Then re-initiate the virtual machine start using VCS or the RHEV-M console.
