Weird, it looks as though port forwards from the guest to the host
didn’t work, although it definitely works here and on hydra:

  https://hydra.gnu.org/job/gnu/master/test.dicod.x86_64-linux
  https://hydra.gnu.org/job/gnu/master/test.exim.x86_64-linux

The build environment lives in a separate network namespace, which I
think means that there cannot be conflicts regarding the TCP ports being
used, so I wonder what could be interfering.
