I have "issues" with later versions of Centos/RHEL 7 also.
PXE boot seems to work, but after the new kernel kexec's, it seems to
drop the NICS and
further in the process for some reason, the nics never come up, which
leads to all kindsof issues of course
(trying to boot a cluster that way). I also have the impression that it
is a dracut issue, however, I have not pinpointed it yet.

Hello,
I am trying to build a PXE boot image for CentOS 7.
livemedia-creator --make-pxe-live --ks=ks --no-virt
It runs the entire process and then it says:
losetup: /dev/: detach failed: Inappropriate ioctl for device
2019-12-26 11:49:47,293: Disk Image install successful
2019-12-26 11:49:47,293: working dir is /var/tmp/tmpKwqC77
mount: /dev/loop0 is write-protected, mounting read-only

I then tried it on CentOS 8 and had the same problem until I installed the dracut-live package but that package doesn't exist on CentOS 7.
I will point out that it seems to work fine with make-iso, just not make-pxe-live. So there is probably a package it needs that I don't know about. Has anyone gotten this to work at all?
Since it is a disk/image issue this is the part of the ks relevant to disks:
# Disk partitioning information
reqpart
part / --fstype="ext4" --size=4000
part swap --size=1000
zerombr
clearpart --all
bootloader --location=mbr
Below is my packages part of my kickstart:
%packages
# Packages needed by anaconda, but not directly required.
# Includes all of the grub2 and shim packages needed, except
# for the grub2-efi-*-cdboot package
@anaconda-tools --optional
@core
anaconda
isomd5sum
kernel
memtest86+
syslinux
-dracut-config-rescue
dell-system-update
# This package is needed to boot the iso on UEFI
grub2-efi-*-cdboot
grub2-efi-ia32
%end
Thanks,
-Drew
