@george1421 im very sorry to make you confused with word “cobbler”, yes, it is an opensource project

if akin to FOG. later, i will try FOG to compare it.

but now, i think my problem is how use dhcp + dnsmasq.proxy mode + ipxe install rhel67(old kernel without efi_stub) with uefi client make it general.

or how gurb2 auto looking for grub.cfg @ ipxe environment.

i was confused that, why grub can’t use anyother args like — grubx64.efi --net_bootp --net_default_server=xxxx --configfile=xxxxx/grub.cfg, or like ipxe support ${mac(ip):hexraw} to make grub.cfg be general. that’s will be perfect to support network install.

how FOG do if someone need install rhel67 with general cfg @ dnsmasq.proxy mode & uefi client(for now all hp gen9 server use efi.)

thank you.

it’s gen by cobbler.

@george1421 in rhel73 @ ipxe, i setting like this.

#!ipxe

dhcp && echo DHCP Succeeded || goto retry_dhcp

:retry_fetch
imgfree

imgfetch http://${next-server}/cblr/svc/op/gpxe/system/${mac:hexraw} && echo Get InstallScript Succeeded && goto start_install || goto fail_sleep

:fail_sleep
echo Fetch/Install failed, sleep 30s && sleep 30 && goto retry_dhcp

:start_install
echo Booting from ${mac:hexraw}
chain ${mac:hexraw} || goto fail_sleep

make bin-x86_64-efi/ipxe.efi EMBED=uefi.ipx

@george1421 is i describe clearly what i need? sorry…

hi @george1421 , see u again.
in my env, i want to use cobbler install rhel67&rhel73 with different mac use diff ksfile.
it’s will be like blow
client get ip with dhcp server & get tftp info with dnsmasq server.
client to tftp server get bootinfo & files.
in legacy bios, it’s works all fine. but uefi.
the first is rhel73.
i solved it cuz rhel73 kernel have bug, change the kernel to centos7.1611 kernel 3.10.514.2.2.
the second is rhel67.
it’s not efi_stub.
i try to use ipxe {kernel tftpserver/vmlinuz, initrd tftpserver/initrd.img, boot} it’s not work.
then, i try ipxe{chain grubx64.efi} it’s give me grub shell, in grub shell { net_bootp, linux tftpserver/vmlinuz, initrd tftpserver/initrd.img, boot} it’s worked.
or i use grub2-mkstandalone balabalbal burn grub.cfg to grubx64.efi, it’s worked too.
but i can’t use these two ways cuz grub shell can’t like ipxe can use script & ${mac:hexraw}, and i can’t make standalone grub.efi with every one client.

so i hear rEFInd like grub. i tried…

is FOG can do this like cobbler?

Description

hi, @Tom-Elliott, after that discussion, i was tring to refind. and i can’t find any way to use refind loading network file. i read the refind doc, it’s support ipxe, but it’s looks like loading refind -> jump to ipxe.efi, not any different between dhcp->ipxe.
and when i try to use refind.conf setting to load manual conf, it’s not support loading network file, like “loader tftp://192.168.136.201/images/rhel64-x86_64/vmlinuz”, but grub support network and tftp, is refind have some setting?

thank you.

@Tom-Elliott google translate was good. if have any problem, can i ask here again?

@Tom-Elliott @george1421 thank you, im came up upon the post from a google search about dnsmasq&pxe boot question.
this is not wok. screen show uefi setting menu. not grub> yet.

pxe-service=BC_EFI,"BC_EFI",grub/grub-x86_64.efi --config-file=grub/efidefault,192.168.136.226

this website advice used in my first post. but static network setting not useful.

thank you @george1421 i tried ipxe, found it’s very powerful. i was working on it to try combine with cobbler.
but it’s looks like redhat 7.3 have a kernel bug for ipxe uefi boot. http://forum.ipxe.org/showthread.php?tid=8243&pid=13314#pid13314
finally solved.

i come from China.:bow_tone2: u know chinese?
thank you for ur help. both.~ 谢谢

@george1421 im not using FOG. only question about pxe booting. use this cuz cobbler default env. im not add/del extra file to it. if default can work. i dont want change any thing.

@Tom-Elliott there no grub.cfg, only cobbler gen efidefault. ofcuz i copy efidefault to /grub.cfg & /boot/grub/grub.cfg, not work, same grub> msg.
