Eelco Dolstra 22693ae44e * Disable wireless in a VM to prevent wpa_supplicant from flooding the
log.

Eelco Dolstra 685335df2f * system.build.system -> system.build.toplevel, since the former name
is just too weird.

Eelco Dolstra 6723473421 * Give some more memory to the VMs.

Eelco Dolstra 7f8272dd70 * Make the host filesystem writable for non-root. This is a temporary
hack to enable non-root processes to write coverage data.

Eelco Dolstra fe329f96ef * Mount the host's /nix/var/nix/db in the guest.

Eelco Dolstra f666aa7479 * With "nixos-rebuild build-vm", override the video driver of
the host (since e.g. "nvidia" won't work in the VM).

Eelco Dolstra 89ef5c979b * New nixos-rebuild action: "nixos-rebuild build-vm" builds a virtual
machine containing a replica (minus the state) of the system
  configuration.  This is mostly useful for testing configuration
  changes prior to doing an actual "nixos-rebuild switch" (or even
  "nixos-rebuild test").  The VM can be started as follows:

  $ nixos-rebuild build-vm
  $ ./result/bin/run-*-vm

  which starts a KVM/QEMU instance.  Additional QEMU options can be
  passed through the QEMU_OPTS environment variable
  (e.g. QEMU_OPTS="-redir tcp:8080::80" to forward a host port to the
  guest).  The fileSystem attribute of the regular system
  configuration is ignored (using mkOverride), because obviously we
  can't allow the VM to access the host's block devices.  Instead, at
  startup the VM creates an empty disk image in ./<hostname>.qcow2 to
  store the VM's root filesystem.

  Building a VM in this way is efficient because the VM shares its Nix
  store with the host (through a CIFS mount).  However, because the
  Nix store of the host is mounted read-only in the guest, you cannot
  run Nix build actions inside the VM.  Therefore the VM can only be
  reconfigured by re-running "nixos-rebuild build-vm" on the host and
  restarting the VM.

Eelco Dolstra f53c9d70ec * The lack of a newline at the end of "EnableSendFile Off" caused a
broken httpd.conf to be generated.  We should really have a merge
  function that appends newlines to every value of options like
  services.httpd.extraConfig.

Eelco Dolstra da77a6437f * qemu-vm.nix: automatically create and initialise the disk image if
it doesn't already exist.  Also set up some ad hoc port forwarding
  from the host to the guest.

Eelco Dolstra 9460a30851 * Use the fileSystems option to mount the host filesystem. Also, it
seems that mount.cifs isn't actually needed (anymore?).

Eelco Dolstra 8179e5213f * A module for building KVM/QEMU virtual machines from a NixOS
configuration.  No virtual disk image is generated; the VM shares a
  Nix store with the host.  This makes it very fast to build new VMs.
