|
This command builds a network of QEMU-KVM virtual machines of a Nix
|
|
expression specifying a network of NixOS machines. The virtual network can
|
|
be started by executing the <filename>bin/run-vms</filename> shell script
|
|
that is generated by this command. By default, a <filename>result</filename>
|
|
symlink is produced that points to the generated virtual network.
|
|

<para>
|
|
A network Nix expression has the following structure:
|
|
<screen>
|
|
{
|
|
test1 = {pkgs, config, ...}:
|
|
{
|
|
services.openssh.enable = true;
|
|
nixpkgs.localSystem.system = "i686-linux";
|
|
deployment.targetHost = "test1.example.net";
|
|
|
|
# Other NixOS options
|
|
};
|
|
|
|
test2 = {pkgs, config, ...}:
|
|
{
|
|
services.openssh.enable = true;
|
|
services.httpd.enable = true;
|
|
environment.systemPackages = [ pkgs.lynx ];
|
|
nixpkgs.localSystem.system = "x86_64-linux";
|
|
deployment.targetHost = "test2.example.net";
|
|
|
|
# Other NixOS options
|
|
};
|
|
}
|
|
</screen>
|
|
Each attribute in the expression represents a machine in the network (e.g.
|
|
<varname>test1</varname> and <varname>test2</varname>) referring to a
|
|
function defining a NixOS configuration. In each NixOS configuration, two
|
|
attributes have a special meaning. The
|
|
<varname>deployment.targetHost</varname> specifies the address (domain name
|
|
or IP address) of the system which is used by <command>ssh</command> to
|
|
perform remote deployment operations. The
|
|
<varname>nixpkgs.localSystem.system</varname> attribute can be used to
|
|
specify an architecture for the target machine, such as
|
|
<varname>i686-linux</varname> which builds a 32-bit NixOS configuration.
|
|
Omitting this property will build the configuration for the same
|
|
architecture as the host system.
