Switch logcat_receiver from vsock to virtio-console

Remove "logcat_port" and replace it with "logcat_pipe_name". Alter the
logcat_receiver to read from a pipe instead of a vsocket. Update the
crosvm and qemu backends to create the hvc2 serial port and update the
init script to write to this new location.

In the guest, logcat can now run as logd, which fixes some long-standing
sepolicy bug_maps. Keep logcat in the root group, so it can access all
the logpersist classes. Remove extraneous sepolicy for writing to a
pipe.

So you want to try cuttlefish?

  1. Download, build, and install the host debian package:
git clone https://github.com/google/android-cuttlefish
cd android-cuttlefish
debuild -i -us -uc -b
sudo dpkg -i ../cuttlefish-common_*_amd64.deb
sudo apt-get install -f
  1. Go to http://ci.android.com/
  2. Enter a branch name. Start with aosp-master if you don't know what you're looking for
  3. Navigate to aosp_cf_x86_phone and click on userdebug for the latest build
  4. Click on Artifacts
  5. Scroll down to the OTA images. These packages look like aosp_cf_x86_phone-img-xxxxxx.zip -- it will always have img in the name. Download this file
  6. Scroll down to cvd-host_package.tar.gz. You should always download a host package from the same build as your images.
  7. On your local system, combine the packages:
mkdir cf
cd cf
tar xvf /path/to/cvd-host_package.tar.gz
unzip /path/to/aosp_cf_x86_phone-img-xxxxxx.zip

  1. Launch cuttlefish with:

    $ HOME=$PWD ./bin/launch_cvd

  2. Stop cuttlefish with:

$ HOME=$PWD ./bin/stop_cvd

So you want to debug cuttlefish?

You can use adb to debug it, just like a physical device:

$ ./bin/adb -e shell

So you want to see cuttlefish?

You can use the TightVNC JViewer. Once you have downloaded the TightVNC Java Viewer JAR in a ZIP archive, run it with

$ java -jar tightvnc-jviewer.jar -ScalingFactor=50 -Tunneling=no -host=localhost -port=6444

Click "Connect" and you should see a lock screen!
