I've put together instructions how to setup QEMU KVM environment to test
EFI PXE booting with PXELinux.
Tomorrow, I want to carry on with a patch for our installer which will
configure DHCP to hand over EFI firmware in case EFI-enabled systems is
Unfortunately for PXELinux one needs to download 6.03-pre20 release to
get this working because EFI support in PXELinux is not as mature as in
Grub 1/2. But since Foreman ships with PXELinux by default, I wanted to
do the same for EFI-based systems.
Both RHEL6 and RHEL7 ship with grub (1 and 2 respectively) and already
contain EFI firmware whould could be probably extracted by our installer
on the TFTP server. We should be able to preconfigure Foreman systems
for EFI PXE booting with Grub. But I don't know if we should make Grub
the default choice for EFI-based systems.
While we could add a feature that would download the syslinux from the
upstream site, unpack and put the right files on the TFTP server too,
this is only doable upstream. For downstream or for those who do not
prefer to install any software that was not delivered by distribution
this is kinda blocker.
Also, I am not sure how Foreman supports Grub1/2 when a host is put into
provision mode. AFAIK grub loader does not load the configuration using
the PXELinux pattern (pxelinux.cfg/MAC-ADDRESS). If we don't have that
support, it is not feasible to ship with Grub as the default option I
What you think?
