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
mount: unknown filesystem type '(null)'
2019-12-26 11:49:52,301: Command '['mount', '-o', 'loop', '/var/tmp/diskJVpsJd.img', '/var/tmp/lorax.imgutils.OtV8Yh']' returned non-zero exit status 32

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
