guest connect to a Unix domain socket on the host rather than the
other way around. The former is a QEMU feature (guestfwd to a
socket) while the latter requires a patch (which we can now get rid
of).

or Google Earth) on 64-bit NixOS on NVIDIA hardware. The 32-bit
OpenGL library is symlinked from /var/run/opengl-driver-32, which is
added to the LD_LIBRARY_PATH so that 32-bit binaries can find it.

function argument, so that the test script can refer to computed
values such as the assigned IP addresses of the virtual machines.

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.

What I want with this derivation is to allow the sheevaplug nixos to
build a tarball with all the needed files to boot. Then, this can be
unpacked into an SD card, or into a NFS/TFTP server, and then the
user can boot the system with help of the uboot console.
By now, I have only tried to build the tarball in a PC, in order
to develop the nix expressions quicker.
There is nothing written specialy for the Sheevaplug in all this,
by now.

* For the block/unblock primitives, use the `set_link' command in the
QEMU monitor.

it special commands such as "screendump", "sendkey" and so on.
* Take screenshots using the "screendump" command. This has the
advantage over "scrot" that it also supports taking a picture of the
console, and is not affected by weird X visuals.

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

So I guess we now depend on a bug in QEMU :-)

* Factored out some commonality between tests to make them a bit
simpler to write. A test is a function { pkgs, ... }: -> { nodes,
testScript } or { machine, testScript }. So it's no longer
necessary to have a "vms" attribute in every test.

write some magic string to ttyS0. This removes the dependency on
having a CIFS mount.
* Use a thread to process the stdout/stderr of each QEMU instance.
* Add a kernel command line parameter "stage1panic" to tell stage 1 to
panic if an error occurs. This is faster than waiting until
connect() times out.
