Fix support for QEMU on non-native architectures. Add the target architecture to the cuttlefish config, inferred from the kernel config. Fix several assumptions about the host architecture being the same as the target. When running on a non-native architecture, default to QEMU, emulate all available CPU features and increase the timeout multiplier to compensate for the slower execution speed. Bug: 161538883 Change-Id: I57ffb1f2af3bdf7ede4db96a27455fef93c14b99
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.
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 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_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_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_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
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!
