Enable UEFI Red Hat support on Cobbler (2.6.7) - HOW?
by Ž D
Hallo. I was successful in UEFI boot and install, here are details:
1) Cobbler server : 2.6.9
source: ?, ?
build time: Fri Jun 12 07:42:24 2015
Cobbler is installed on Oracle Linux 6.6
2) I am installing Oracle Linux R6-U6-x86_64 on the Oracle Server x3-2
3) DHCP service is provided by another box, the config is:
host my-hostname.domain.com {
hardware ethernet 00:10:e0:aa:aa:aa;
fixed-address 10.xx.xx.xx;
next-server 10.yy.yy.yy; # my cobbler server
filename "/grub/BOOTX64.efi";
}
4) How to find proper BOOTX64.efi file, read the doc:
http://docs.oracle.com/cd/E37670_01/E41137/E41137.pdf
See the paragraph 1.4.7 (starts on page 9), the page 10 talks about
UEFI-based PXE client.
This is the key: UEFI-based PXE clients can use the BOOTX64.efi boot
loader, which is available as EFI/BOOT/BOOTX64.efi from the Oracle Linux
6 Update 6 Media Pack DVD image.
So I placed BOOTX64.efi in <my_cobbler_server>:/var/lib/tftpboot/grub/
5) I also have the file splash.xpm.gz in
<my_cobbler_server>:/var/lib/tftpboot/grub/
6) The file /var/lib/tftpboot/grub/00:10:e0:aa:aa:aa looks like
timeout=10
splashimage=(nd)/splash.xpm.gz
title OL-R6-U6-x86_64-UEFI
root (nd)
kernel /images/OL-R6-U6-x86_64/vmlinuz ksdevice=bootif lang= text
ks=http://my_cobbler_server/cblr/svc/op/ks/system/host_name
initrd /images/OL-R6-U6-x86_64/initrd.img
7) The kickstart file is
# ks for OL 6.6 UEFI
install

8) Works for me. Let me know if you need any other detail?
