Add -gdb_port to replace -qemu_gdb crosvm supports kernel gdb now, but only in TCP/IP mode, so remove the old qemu_gdb 'flag' and replace it with another flag which is specifically only to specify the gdb port. This also adds '-S' to the command line for QEMU, so it waits for the debugger to connect, like the crosvm support unconditionally does. On crosvm, the support is still quite limited; only x86_64 is supported, and only UP (single processor) for now. This change requires the user to explicitly specify '-cpus 1' so as to not break SMP debugging with QEMU. Bug: 178531428 Change-Id: Ia07f660c2568f89f256111cb3ab3cdb8640e51f2
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!
