79073c7b3d Adding a virtualisation option: run qemu without graphics.

6c9059e717 * Added an option `boot.initrd.availableKernelModules' that specifies
modules that should be added to the initrd, but should only be
  loaded on demand (e.g. by the kernel or by udev).  This is
  especially useful in the installation CD, where we now only load the
  modules needed by the hardware.
* Enable automatic modprobing by udev in the initrd.

d545d08461 * In the network-interfaces task, emit an ip-up event if there is a
statically configured interface (i.e. we're not running dhclient).
  Otherwise the ntpd job won't be triggered.
* Use the "-n" flag of "initctl emit" to send the event
  asynchronously.

3e9665dd96 * X server autoconfiguration. Rather than specifying a fixed video
driver (in services.xserver.videoDriver), the X server is now given
  a set of drivers, and will use PCI ids to find the right one.

  The only problem is that the choice of OpenGL driver (the
  /var/run/opengl-driver symlink) depends on what driver is selected
  at runtime (i.e. the NVIDIA implementation for "nvidia", and Mesa
  for all other drivers).  However this isn't a big problem right now
  since "nvidia" isn't included in the default set of drivers anyway
  for legal reasons.
  
* `services.xserver.resolutions' now defaults to [], meaning that the
  X server should figure out the desired resolution(s) itself.
  Likewise, `services.xserver.defaultDepth' defaults to 0 to let the X
  server figure it out.

* Removed some options from xorg.conf that no longer appear needed
  ("Composite" and the DRI "Mode").

the host (since e.g. "nvidia" won't work in the VM).

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.

f53c9d70ec * The lack of a newline at the end of "EnableSendFile Off" caused a
broken httpd.conf to be generated.  We should really have a merge
  function that appends newlines to every value of options like
  services.httpd.extraConfig.

8179e5213f * A module for building KVM/QEMU virtual machines from a NixOS
configuration.  No virtual disk image is generated; the VM shares a
  Nix store with the host.  This makes it very fast to build new VMs.
