mkdir -p snapshot_path mkdir -p for snapshot path is using EnsureDirectoryExists(). EnsureDirectoryExists() should consider link to directory, though. Say, in the path "/a/b/L/d," L is a link to the directory c. "/a/b/L" and "/a/b/c" exists while "/a/b/c/d" does not. Then, EnsureDirectoryExists() should only create d under "/a/b/L" or "/a/b/c."

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 packages:
sudo apt install -y git devscripts config-package-dev debhelper-compat golang curl git clone https://github.com/google/android-cuttlefish cd android-cuttlefish for dir in base frontend; do cd $dir debuild -i -us -uc -b -d cd .. done sudo dpkg -i ./cuttlefish-base_*_*64.deb || sudo apt-get install -f sudo dpkg -i ./cuttlefish-user_*_*64.deb || sudo apt-get install -f sudo usermod -aG kvm,cvdnetwork,render $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
aosp-master-throttled-copped
and device target aosp_cf_arm64_only_phone-userdebug
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
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.
You will need to stop the virtual device within the same directory as you used to launch the device.
$ HOME=$PWD ./bin/stop_cvd
