=E2=80=98guix system vm-image=E2=80=99 produces an image that expects QEMU=
=E2=80=99s networking
interface available as eth0 inside the host, hence the error you were
getting.

To enable that, I think you need to do:

  qemu-system-x86_64 -net user -net nic,model=3Dvirtio =E2=80=A6

See:

  https://www.gnu.org/software/guix/manual/html_node/Running-GuixSD-in-a-VM=
.html

Could you try and report back?

Thanks,
