- 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 svn path=/nixos/trunk/; revision=24410 2010-10-21 15:50:12 -07:00			`, networkExpr`

* nixos-build-vms/build-vms.nix: drop the "nixos" function argument, since the path to the NixOS source tree is known. svn path=/nixos/trunk/; revision=26989 2011-04-27 06:01:42 -07:00			`let nodes = import networkExpr; in`

Fixed nixos-build-vms to use the new test driver. Backdoor option does not work anymore though. I have to look for another solution svn path=/nixos/trunk/; revision=25591 2011-01-16 13:57:09 -08:00
