it doesn't turn blue backgrounds into yellow (see

* 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

init script.  This removes the need for the `systemConfig' boot

  builder still needs to add `systemConfig' to the kernel command line
  for compatibility with old configurations.

  it allows testing of GRUB.

  to be set to "nodev" to indicate that the GRUB menu should be
  generated without installing GRUB.  For the second, add an option

Eelco Dolstra e2dbfbdcf4 * Use writeback caching for virtual disks instead of writethrough

  ‘cache=writethrough’, most notably, qcow2."

  1, so stage 2 doesn't need to set them up again.

2010-06-01 15:53:24 +00:00
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 :-)

compression this shouldn't be expensive.

Eelco Dolstra 12a0a68749 * Initialise the Nix database in the VM.

Eelco Dolstra 3e3448a7df * Added an Upstart job to fetch the SSH key for logging into the root
account of the VM.  However, it doesn't work yet (the machine
  doesn't boot properly and there is no console output).  So use a
  hard-coded password for now (very dangerous!).

Eelco Dolstra 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.

Eelco Dolstra 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.

Eelco Dolstra 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").
