Eelco Dolstra 9692495df0 Use BusyBox in the initrd
Using BusyBox instead of Bash plus a bunch of other tools gives us a
much more feature-full, yet smaller initrd.  In particular, BusyBox
contains networking commands such as ip and a DHCP client, useful for
NFS boots.  It's also much more convenient for rescue situations
because the shell has builtin readline support and there are many more
tools (including vi).

Peter Simons 20b364f4de Reverting revisions 30103-30106: "always set nixpkgs.config.{state,store}Dir", etc.
After the change from revision 30103, nixos-rebuild suddenly consumed
freaky amounts of memory. I had to abort the process after it had
allocated well in excess of 30GB(!) of RAM. I'm not sure what is causing
this behavior, but undoing that assignment fixes the problem. The other
two commits needed to be revoked, too, because they depend on 30103.

Eelco Dolstra 796b48c367 * Run smbd in its own session / process group (setsid) because smbd
now kills its process group when it exits.  Without setsid, this
  ends up killing the parent (i.e., the builder).
* Use port 445 instead of 139 because the CIFS kernel module tries
  port 445 first.  If there is an actual Samba running on the host, it
  would end up connecting to that one instead of our own and fail.

Sander van der Burg 9c722e474d - Added nixos-build-vms command, which builds a virtual network from a network.nix expression (also used by nixos-deploy-network)
- Added a backdoor option to the interactive run-vms script. This allows me to intergrate the virtual network approach with Disnix
- Small documentation fixes

Some explanation:

The nixos-build-vms command line tool can be used to build a virtual network of a network.nix specification.
For example, a network configuration (network.nix) could look like this:

{
  test1 = 
    {pkgs, config, ...}:
 
    {
      services.openssh.enable = true;
      ...
    };

  test2 =
    {pkgs, config, ...}:
    
    {
      services.openssh.enable = true;
      services.xserver.enable = true;
    }

    ;
}

By typing the following instruction:

$ nixos-build-vms -n network.nix

a virtual network is built, which can be started by typing:

$ ./result/bin/run-vms

It is also possible to enable a backdoor. In this case *.socket files are stored in the current directory
which can be used by the end-user to invoke remote instruction on a VM in the network through a Unix
domain socket.

For example by building the network with the following instructions:

$ nixos-build-vms -n network.nix --use-backdoor

and launching the virtual network:

$ ./result/bin/run-vms

You can find two socket files in your current directory, namely: test1.socket and test2.socket.
These Unix domain sockets can be used to remotely administer the test1 and test2 machine
in the virtual network.

For example by running:

$ socat ./test1.socket stdio
ls /root

You can retrieve the contents of the /root directory of the virtual machine with identifier test1

Eelco Dolstra c4f910f550 * Substitute the path of the system derivation directly in the stage 2
init script.  This removes the need for the `systemConfig' boot
  parameter; `init=<stage-2-init>' is enough.  However, the GRUB menu
  builder still needs to add `systemConfig' to the kernel command line
  for compatibility with old configurations.

Eelco Dolstra c1295661c4 * Added a command `nixos-rebuild build-vm-with-bootloader'. This is
like `build-vm', but boots using the regular boot loader (i.e. GRUB
  1 or 2) rather than booting directly from the kernel/initrd.  Thus
  it allows testing of GRUB.

  socket) while the latter requires a patch (which we can now get rid
  of).

Eelco Dolstra e2dbfbdcf4 * Use writeback caching for virtual disks instead of writethrough
caching.  This makes a huge performance difference (e.g. from 4 MB/s
  `dd' throughput to 140 MB/s on the Hydra machines).  As the QEMU
  manual says: "Some block drivers perform badly with
  ‘cache=writethrough’, most notably, qcow2."

  factor of 5).

  FS.  It automatically moves over the /dev, /proc and /sys from stage
  1, so stage 2 doesn't need to set them up again.

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 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 :-)
