There are some (mostly ISP-specific) name servers who will redirect non-existing domains to special hosts. In this case, we will get a different error message when trying to connect to such a host, which breaks test 162. 162 needed this specific error message so it can confirm that qemu was indeed trying to connect to the user-specified port. However, we can also confirm this by setting up a local NBD server on exactly that port; so we can fix the issue by doing just that.
