I found the way to create custom DVD from the RHEL7 page.

  1. Mount the downloaded image

    mount -t iso9660 -o loop path/to/image.iso /mnt/iso

  2. Create a working directory - a directory where you want to place the contents of the ISO image.

    mkdir /tmp/ISO

  3. Copy all contents of the mounted image to your new working directory. Make sure to use the -p option to preserve file and directory permissions and ownership.

    cp -pRf /mnt/iso /tmp/ISO

  4. Unmount the image.

    umount /mnt/iso

  5. Make sure your current working directory is the top-level directory of the extracted ISO image - e.g. /tmp/ISO/iso. Create the new ISO image using genisoimage:

    genisoimage -U -r -v -T -J -joliet-long -V "RHEL-7.1 Server.x86_64" -Volset "RHEL-7.1 Server.x86_64" -A "RHEL-7.1 Server.x86_64" -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -eltorito-alt-boot -e images/efiboot.img -no-emul-boot -o ../NEWISO.iso .

Hope the answer will helpful:

I am editing my answer due to the comments posted. Here is a more comprehensive solution:

(A) You need to create the ISO properly. I found helpful information in this URL.

Here is the line that I actually ended up with, for my MBR/UEFI ISO creation:

mkisofs -U -A "<Volume Header>" -V "RHEL-7.1 x86_64" -volset "RHEL-7.1 x86_64" -J -joliet-long -r -v -T -x ./lost+found -o ${OUTPUT}/${HOST}.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -eltorito-alt-boot -e images/efiboot.img -no-emul-boot -boot-load-size 18755 /dir/where/sources/for/ISO/are/located

Be careful with the -V parameter, as it has to match what the kernel has defined for inst.stage2. In the default grub.conf included in the boot disk, it is configured to be "hd:LABEL=RHEL-7.1\x20x86_64" which matches with the settings above.

(B) You need the correct setup for EFI for RHEL7. For some reason, this has changed from RHEL6, where you could just use the /EFI/BOOT/BOOTX64.conf. Now it uses the /EFI/BOOT/grub.cfg. Common wisdom from Red Hat Manuals state to add the inst.ks= parameter to the kernel line. The grub.cfg that comes in the /EFI/BOOT directory of the RHEL7 boot iso actually has the linuxefi parameter, instead of the kernel one, I would guess they would work the same. If you are including the KS file on the CD, this should get you there.

Good Luck!

You need to use the new command. Here is an example of what will work:

  • Add the kickstart file to your download and exploded ISO.

  • Run this command in the area with the ISO and kickstart and point to another location to build the ISO:

    genisoimage -r -v -V "OEL6 with KS for OVM Manager" -cache-inodes -J -l -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o OEL6U6_OVM_Manager.iso /var/www/html/Template/ISO/

Edit the ISO image and put the ks.cfg file that you have created. Preferably, put the ks.cfg file inside ks directory. More information can be found here.
