As promised, here I am now with UEFI issues. :)
I've finished getting BIOS boots/installs working fine. Now I want to
add UEFI support, and I'm hitting a road block right out of the gate.
First, do you have docs/links/reference material you might recommend on
building a Fedora-based UEFI PXE server? I'd love to try and get further
on my own and keep questions to a minimum.
Right now, I've got a KVM/qemu guest configured with UEFI. I've setup
the following;
====
[root@f28-striker01 fedora28]# cat /etc/dhcp/dhcpd.conf
### Global options
option domain-name "alteeve.com";
option domain-name-servers 8.8.8.8, 8.8.4.4;
authoritative;
ddns-update-style none;
# refer to RFC4758 for possible arch option values
option arch code 93 = unsigned integer 16;
subnet 10.1.0.0 netmask 255.255.0.0 {
default-lease-time 600;
max-lease-time 7200;
range 10.1.14.1 10.1.14.254;
option routers 10.1.4.1;
if option arch = 00:07 {
filename "uefi/shim.efi";
} else {
filename "pxelinux.0";
}
next-server 10.1.4.1;
}

insmod all_video

When I PXE boot the UEFI guest, it gets the IP from the PXE server,
downloads uefi/shim.efi, then hangs on 'Fetching Netboot image'. It
never shows a menu.
==== (on EFI guest, transcribed manually)
>>Start PXE over IPv4
Station IP address is 10.1.14.186
Server IP address is 10.1.4.1
NBP filename is uefi/shim.efi
NBP filesize is 1210776 Bytes

NBP file downloaded successfully.

And there it hangs. I'm not sure how to debug to see more detail on what
it is trying to do. This UEFI PXE booting is totally new for me, so I
may be missing something terribly obvious.
Thanks!
