Running guix GNU Hurd build

Hi, I wonder is there any documentation on running the GNU Guix Hurd
build... I can run the latest snapshot build image on a KVM on top of
an x86-64 GNU/Linux host (Fedora) to the point of logging in as root
(text mode, login shell) but cannot get networking to work...

For comparison, the latest Debian GNU/Hurd image (202108) can reach
the point of running X windows with LXDE or icewm, with networking so
I was able to update the system from Debian servers..

Thanks for info.
