Eelco Dolstra 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).

Eelco Dolstra 77a4004df1 * The installer test lost the QEMU flags to set up the NIC to talk to
the web server somewhere, so put them back in
  (http://hydra.nixos.org/build/424923).

Eelco Dolstra 4dac9e5814 * Allow more complex network topologies in distributed tests. Each
machine can now declare an option `virtualisation.vlans' that causes
  it to have network interfaces connected to each listed virtual
  network.  For instance,

    virtualisation.vlans = [ 1 2 ];

  causes the machine to have two interfaces (in addition to eth0, used
  by the test driver to control the machine): eth1 connected to
  network 1 with IP address 192.168.1.<i>, and eth2 connected to
  network 2 with address 192.168.2.<i> (where <i> is the index of the
  machine in the `nodes' attribute set).  On the other hand,
  
    virtualisation.vlans = [ 2 ];

  causes the machine to only have an eth1 connected to network 2 with
  address 192.168.2.<i>.  So each virtual network <n> is assigned the
  IP range 192.168.<n>.0/24.

  Each virtual network is implemented using a separate multicast
  address on the host, so guests really cannot talk to networks to
  which they are not connected.

* Added a simple NAT test to demonstrate this.

* Added an option `virtualisation.qemu.options' to specify QEMU
  command-line options.  Used to factor out some commonality between
  the test driver script and the interactive test script.

Eelco Dolstra 55c349fe20 * Added a test that checks whether users can log in on a virtual
console.  This uses the `sendkey' command in the QEMU monitor.
* For the block/unblock primitives, use the `set_link' command in the
  QEMU monitor.

Eelco Dolstra fc805fe541 * In the test driver, connect to the QEMU monitor so that we can send
it special commands such as "screendump", "sendkey" and so on.
* Take screenshots using the "screendump" command.  This has the
  advantage over "scrot" that it also supports taking a picture of the
  console, and is not affected by weird X visuals.

Eelco Dolstra fc583b7054 * When QEMU encounters a "disk full" condition on the host filesystem,
its default behaviour is to stop the emulator (i.e. suspend the VM).
  For automated tests, this is bad, because is makes the VM appear to
  hang without any error message.  The "werror=report" flag causes
  QEMU to report the problem to the VM.  As a side effect QEMU exits
  very elegantly:

    [    2.308668] end_request: I/O error, dev vda, sector 534400
    [    2.309611] Buffer I/O error on device vda, logical block 66800
    ...
    *** glibc detected *** /nix/store/yhngqrww53j0aw7z7v4bv948x5g5fc3d-qemu-kvm-0.12.1.2/bin/qemu-system-x86_64: double free or corruption (!prev): 0x08e3e040 ***
    Aborted

  So I guess we now depend on a bug in QEMU :-)

Eelco Dolstra 170331be30 * Don't use /hostfs to signal the test driver that a VM is up, but
write some magic string to ttyS0.  This removes the dependency on
  having a CIFS mount.
* Use a thread to process the stdout/stderr of each QEMU instance.
* Add a kernel command line parameter "stage1panic" to tell stage 1 to
  panic if an error occurs.  This is faster than waiting until
  connect() times out.

Eelco Dolstra 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.)
