Lluís Batlle i Rossell 1dd3162d7c First attempt at trying to get a tarball of a bootable nixos system.
What I want with this derivation is to allow the sheevaplug nixos to
build a tarball with all the needed files to boot. Then, this can be
unpacked into an SD card, or into a NFS/TFTP server, and then the
user can boot the system with help of the uboot console.
By now, I have only tried to build the tarball in a PC, in order
to develop the nix expressions quicker.

There is nothing written specialy for the Sheevaplug in all this,
by now.

  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 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.)

Eelco Dolstra 2892aed712 * lib/eval-config.nix: combined "configuration" and "extraModules"
into one argument "modules".
* release.nix: fixed the manual job.
* ISO generation: break an infinite recursion.  Don't know why this
  suddenly happens.  Probably because of the nixpkgs.config change,
  but I don't see why.  Maybe the option evaluation is too strict.

svn path=/nixos/trunk/; revision=16878
2009-08-27 11:57:43 +00:00
Eelco Dolstra 6f1b1aefde * Added an option `nixpkgs.config' that allows the Nixpkgs options to
be set from the NixOS configuration.  For instance, you can say

    nixpkgs.config.firefox.enableGeckoMediaPlayer = true;

    environment.systemPackages = [ pkgs.firefox ];

  but the more interesting application is to apply global overrides to
  Nixpkgs throughout NixOS, e.g.

    nixpkgs.config.packageOverrides = pkgs:
      { glibc = pkgs.glibc27;
        gcc = pkgs.gcc42;
      };

  would build the whole system with Glibc 2.7 and GCC 4.2.  (There are
  some issues with "useFromStdenv" in all-packages.nix that need to be
  fixed for packages in the stdenv bootstrap though.)

  The implementation of this option is kind of evil though due to the
  need to prevent a circularity between the evaluation of
  nixpkgs.config and the "pkgs" module argument.

2009-08-21 09:08:55 +00:00
Eelco Dolstra 89ef5c979b * New nixos-rebuild action: "nixos-rebuild build-vm" builds a virtual
machine containing a replica (minus the state) of the system
  configuration.  This is mostly useful for testing configuration
  changes prior to doing an actual "nixos-rebuild switch" (or even
  "nixos-rebuild test").  The VM can be started as follows:

  $ nixos-rebuild build-vm
  $ ./result/bin/run-*-vm

  which starts a KVM/QEMU instance.  Additional QEMU options can be
  passed through the QEMU_OPTS environment variable
  (e.g. QEMU_OPTS="-redir tcp:8080::80" to forward a host port to the
  guest).  The fileSystem attribute of the regular system
  configuration is ignored (using mkOverride), because obviously we
  can't allow the VM to access the host's block devices.  Instead, at
  startup the VM creates an empty disk image in ./<hostname>.qcow2 to
  store the VM's root filesystem.

  Building a VM in this way is efficient because the VM shares its Nix
  store with the host (through a CIFS mount).  However, because the
  Nix store of the host is mounted read-only in the guest, you cannot
  run Nix build actions inside the VM.  Therefore the VM can only be
  reconfigured by re-running "nixos-rebuild build-vm" on the host and
  restarting the VM.

  instead of

    require = [ /etc/nixos/nixos/hardware/network/intel-3945abg.nix ];

  The latter is bad because it makes it hard to build from a different
  NixOS source tree.

Eelco Dolstra e4e408293e * Modularise the building of the installation CD/DVD. The module
iso-image.nix contains the minimal stuff necessary to build a
  bootable ISO image containing the given configuration.  The idea is
  that this can be customised by providing additional modules, e.g. to
  add extra packages to the image.

  The ISO image is exported in the configuration attribute
  system.build.isoImage.  So it can be built as follows:

  $ nix-build lib/eval-config.nix \
      --arg configuration 'import ./modules/installer/cd-dvd/iso-image.nix' \
      -A config.system.build.isoImage
