Host-side binary for Android Virtual Device

Launcher package

This is the cuttlefish launcher implementation, that integrates following features:

  • libvirt domain configuration,
  • ivshmem server,
  • USB forwarding.

Overview

ivshmem

We are breaking from the general philosophy of ivshmem-server inter-vm communication. In this prototype there is no concept of inter-vm communication; guests can only talk to daemons running on host.

Requirements

Cuttlefish requires the following packages to be installed on your system:

Compiling:

  • libjsoncpp-dev
  • libudev-dev,
  • libvirt-dev,
  • libxml2-dev

Running:

  • linux-image-extra-virtual to supply vhci-hcd module (module must be loaded manually)
  • libvirt-bin
  • libxml2
  • qemu-2.8 (or newer)

Building and Installing debian package

To build debian package:

host$ cd dist
host$ debuild --no-tgz-check -us -uc
host$ cd ..
host$ scp cuttlefish-common*.deb ${USER}@123.45.67.89:

This will create file named cuttlefish-common_0.1-1_amd64.deb in the root folder of your workspace. You will have to manually upload this file to your remote instance and install it as:

host$ ssh 123.45.67.89
gce$ sudo apt install -f --reinstall ./cuttlefish-common*.deb

apt will pull in all necessary dependencies. After it's done, support files will be ready to use.

Host Configuration

All configuration and basic deployment is covered by scripts in the host/deploy folder. To configure remote instance for cuttlefish, execute:

host$ cd host/deploy
host$ python main.py config -i 123.45.67.89

The script will automatically update libvirt configuration files and user group membership, as well as create necessary folder for Cuttlefish images.

Uploading images

To deploy cuttlefish images from build server, execute:

host$ cd host/deploy
host$ python main.py deploy -i 123.45.67.89

By default, the script will pull the latest build of cf_x86_phone-userdebug target from oc-gce-dev branch, and latest kernel from cuttlefish kernel target and branch. Both system and kernel locations can be tuned by supplying relevant arguments via command line.

Optionally, files can be populated and uploaded manually. Please ensure that at all times user libvirt-qemu can access each of these files by specifying correct ACL permissions using setfacl command, eg:

gce$ setfacl -m u:libvirt-qemu:rw /path/to/system.img

Starting Cuttlefish

To start cuttlefish, assuming you executed all the above:

gce$ sudo modprobe vhci-hcd
gce$ sudo cf -system_image_dir /srv/cf/latest/ \
        -kernel /srv/cf/latest/kernel \
        -data_image /srv/cf/latest/data.img \
        -cache_image /srv/cf/latest/cache.img \
        --logtostderr

Shortly after, you should be able to execute adb devices and see your device listed. If device is reported as ????????, or as:

CUTTLEFISHCVD01 no permissions (verify udev rules); see [http://developer.android.com/tools/device.html]

you may have to re-start adb as root (we don't have udev rules updating virtual usb permissions yet):

gce$ adb kill-server
gce$ sudo adb devices
