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. svn path=/nixos/trunk/; revision=21928		2010-05-20 21:07:32 +00:00
