1cde1bdbe6 nixos-run-vms: If there is only one VM, attach stdio to its serial console
This is useful for interactive testing (quicker than logging in via
SSH and more convenient than logging in via a virtual console).

1d0c23bffb * Use a raw disk for the installer test. This speeds it up by almost
two minutes on my laptop.  Note that due to sparse allocation, raw
  disks don't actually take up more space than qcow2 disks (and
  they're temporary anyway).

158a60465f * The vde_switch startup code was reading from the wrong filehandle,
so the startup synchronisation didn't work, causing spurious QEMU
  failures ("Device 'vde' could not be initialized").

b3dbcbe249 * Use vde_switch instead of QEMU's multicast feature to tie QEMU VMs
together into virtual networks.  This has several advantages:

  - It's more secure because the QEMU instances use Unix domain
    sockets to talk to the switch.

  - It doesn't depend on the host's network interfaces.  (Local
    multicast fails if there is no default gateway, so for instance it
    fails if a laptop is not connected to any network.)

  - VDE devices can be connected together to form arbitrary network
    topologies.

  - VDE has a "wirefilter" tool to emulate delays and packet loss,
    which are useful for network testing.

445827ad45 * Added a convenience derivation for running the test driver
interactively on a network specification.  For instance:

  $ nix-build tests/ -A quake3.driver
  $ ./result/bin/nixos-test-driver
  > startAll;
  client1: starting vm
  client1: QEMU running (pid 14971)
  server: starting vm
  server: QEMU running (pid 14982)
  ...
  > $client1->execute("quake3 ...");

* Use the GNU readline library in interactive mode.

363806e89b * To establish the connection to the root shell in the guest, let the
guest connect to a Unix domain socket on the host rather than the
  other way around.  The former is a QEMU feature (guestfwd to a
  socket) while the latter requires a patch (which we can now get rid
  of).

  QEMU monitor.

27a8e656bc * Stuff for automatic and manual testing of NixOS VMs.
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.

  (Moved from the vario repository.)
