Working with lorax-25.16-1 on a Fedora 25 x86_64 KVM virtual machine and trying to use livemedia-creator as documented here:

https://fedoraproject.org/wiki/Livemedia-creator-_How_to_create_and_use_a_Live_CD

It was working for me with the previous lorax release but the update to lorax-25.16-1, the anaconda server starts but it can never connect to it.  I have tried several times over several reboots and still the same thing on two different build systems that were previously working.

Here's what my command line looks like:

setenforce 0
livemedia-creator \
  --no-virt \
  --ks /root/livemedia-creator/MontanaLinux/MontanaLinux-F25-x86_64.ks \
  --project MontanaLinux \
  --title MontanaLinux \
  --releasever 25 \
  --iso-only \
  --make-iso \
  --volid MontanaLinux-F25-x86_64 \
  --logfile=/root/livemedia-creator/livemedia.log \
  --iso-name MontanaLinux-F25-054-x86_64.iso

I have turned off firewalld.service on the build host (although I thought 127.0.0.1 was a trusted device and connections wouldn't be denied) but that hasn't helped.

I can provide my kickstart file if needed... but I assume this error is reproducable by others.  If not, please let me know.
