158a60465f * The vde_switch startup code was reading from the wrong filehandle,
so the startup synchronisation didn't work, causing spurious QEMU
  failures ("Device 'vde' could not be initialized").

b3dbcbe249 * Use vde_switch instead of QEMU's multicast feature to tie QEMU VMs
together into virtual networks.  This has several advantages:

  - It's more secure because the QEMU instances use Unix domain
    sockets to talk to the switch.

  - It doesn't depend on the host's network interfaces.  (Local
    multicast fails if there is no default gateway, so for instance it
    fails if a laptop is not connected to any network.)

  - VDE devices can be connected together to form arbitrary network
    topologies.

  - VDE has a "wirefilter" tool to emulate delays and packet loss,
    which are useful for network testing.

  of).

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.

fc805fe541 * In the test driver, connect to the QEMU monitor so that we can send
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.

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 :-)

170331be30 * Don't use /hostfs to signal the test driver that a VM is up, but
write some magic string to ttyS0.  This removes the dependency on

* 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.
