Description of problem:

Hello.

I have a Fedora 25 using "lorax-25.19-1.fc25.x86_64" package to build live pxe boot squashfs image.

I'm using the following command

livemedia-creator --make-pxe-live --image-name=my_fedora_img --tmp=/var/tmp/a --ks fedora25-my.ks --iso=Fedora-Workstation-netinst-x86_64-25-1.3.iso

The "fedora25-my.ks" is pretty basic:

url --mirrorlist=https://mirrors.fedoraproject.org/mirrorlist?repo=fedora-$releasever&arch=$basearch
lang en_US.UTF-8
keyboard us
timezone --utc Etc/UTC
network --bootproto=dhcp --device=link --activate
rootpw root
shutdown
zerombr
clearpart --all --initlabel --disklabel=msdos
part / --size 5120 --fstype ext4
bootloader --timeout=1 --append="no_timer_check console=tty1 console=ttyS0,115200n8"

%packages
@core
dracut-live
%end

Qemu did the job and generates the image, but then I got the error:
