Check that TAP devices aren't in use.

This is just a sanity check at the moment to avoid multiple VMMs using
the same TAP device. Looking at the list of tap devices in use will in
the future help with selecting available instance numbers / indexes to
run a device in.

Prior to this change, if the TAP device was already being used,
run_cvd would run without that tap device and print
"Unable to connect to ..tap interface: Device or resource busy".
This makes run_cvd fail outright if the tap device is already being used
by another process.

Test: Build and run when TAP device is in use (through vde_plug2tap)

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!
