Add boilerplate for remote IC HAL to Cuttlefish The identity credential HAL needs to be changed to a remote HAL (like KeyMint) so that the backend can communicate with KeyMint for attestation. Before doing so, essentially copy the default service as a starting point. The requirement starts with the upcoming V4 of the identity service interface, so pin the identity credential HAL to V3 on cuttlefish until we can implement the remote service.

Make sure virtualization with KVM is available.
grep -c -w "vmx\|svm" /proc/cpuinfo
This should return a non-zero value. If running on a cloud machine, this may take cloud-vendor-specific steps to enable. For Google Compute Engine specifically, see the GCE guide.
ARM specific steps:
/dev/kvm
. Note that this method can also be used to confirm support of KVM on any environment.Download, build, and install the host debian package:
sudo apt install -y git devscripts config-package-dev debhelper-compat git clone https://github.com/google/android-cuttlefish cd android-cuttlefish debuild -i -us -uc -b sudo dpkg -i ../cuttlefish-common_*_*64.deb || sudo apt-get install -f sudo usermod -aG kvm,cvdnetwork $USER sudo reboot
The reboot will trigger installing additional kernel modules and applying udev rules.
Go to http://ci.android.com/
Enter a branch name. Start with aosp-master
if you don‘t know what you’re looking for
Navigate to aosp_cf_x86_64_phone
and click on userdebug
for the latest build
Click on Artifacts
Scroll down to the OTA images. These packages look like aosp_cf_x86_64_phone-img-xxxxxx.zip
-- it will always have img
in the name. Download this file
Scroll down to cvd-host_package.tar.gz
. You should always download a host package from the same build as your images.
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_64_phone-img-xxxxxx.zip
Launch cuttlefish with:
$ HOME=$PWD ./bin/launch_cvd
$ HOME=$PWD ./bin/stop_cvd
You can use adb
to debug it, just like a physical device:
$ ./bin/adb -e shell
When launching with ---start_webrtc
(the default), you can see a list of all available devices at https://localhost:8443
. For more information, see the WebRTC on Cuttlefish documentation.
