automatically. This is mostly useful for testing. (KDM also has
this feature, but it's nice not to depend on KDE for non-KDE tests.)

* Factored out some commonality between tests to make them a bit
simpler to write. A test is a function { pkgs, ... }: -> { nodes,
testScript } or { machine, testScript }. So it's no longer
necessary to have a "vms" attribute in every test.

Manually removing socket file. Somehow the socket is not always created
when rebooting the second time (?) I have to look into that later.

expose makeInfo (used by test now)
expose config hack
* Adding tests to release.nix
* fixes
* removing dependency on perl
refactoring details:
Move all configuration modules used by the NixOS installation test script
into one directory.

You can run the kvm nixos installation test by:
nix-build --no-out-link tests/test-nixos-install-from-cd.nix
It boots the installed system.
It still fails sshd isn't started (yet)
adding nixos-bootstrapping-archive:
You can install NixOS easily using any live cd now.

printing a remote controlled "Hello".
This serves as example how to run a vm within a bulid job.

3 server and two clients. The clients connect to the server and do
nothing (except getting blown by the bots). After a few seconds we
verify that the clients indeed connected successfully, and make a
screenshot of the X displays of the clients.

lib/build-vms.nix contains a function `buildVirtualNetwork' that
takes a specification of a network of machines (as an attribute set
of NixOS machine configurations) and builds a script that starts
each configuration in a separate QEMU/KVM VM and connects them
together in a virtual network. This script can be run manually to
test the VMs interactively. There is also a function `runTests'
that starts and runs the virtual network in a derivation, and
then executes a test specification that tells the VMs to do certain
things (i.e., letting one VM send an HTTP request to a webserver on
another VM). The tests are written in Perl (for now).
tests/subversion.nix shows a simple example, namely a network of two
machines: a webserver that runs the Subversion subservice, and a
client. Apache, Subversion and a few other packages are built with
coverage analysis instrumentation. For instance,
$ nix-build tests/subversion.nix -A vms
$ ./result/bin/run-vms
starts two QEMU/KVM instances. When they have finished booting, the
webserver can be accessed from the host through
http://localhost:8081/.
It also has a small test suite:
$ nix-build tests/subversion.nix -A report
This runs the VMs in a derivation, runs the tests, and then produces
a distributed code coverage analysis report (i.e. it shows the
combined coverage on both machines).
The Perl test driver program is in lib/test-driver. It executes
commands on the guest machines by connecting to a root shell running
on port 514 (provided by modules/testing/test-instrumentation.nix).
The VMs are connected together in a virtual network using QEMU's
multicast feature. This isn't very secure. At the very least,
other processes on the same machine can listen to or send packets on
the virtual network. On the plus side, we don't need to be root to
set up a multicast virtual network, so we can do it from a
derivation. Maybe we can use VDE instead.
