Wang Ningyuan 3fd003cefc e2e_tests: Use distinct tap name for each e2e test In e2e tests, error 16 is thrown when a tap device is created when its name is shared with another tap device. This makes the test flaky. Distinct tap name is needed.

Crosvm End to End Tests

These tests run a crosvm VM on the host to verify end to end behavior. They use a prebuilt guest kernel and rootfs, which is downloaded from google cloud storage.

The e2e_tests can be executed by:

$ ./tools/run_tests --dut=vm -E 'rdeps(e2e_tests)'

Running with locally built kernel/rootfs

If you want to make changes to the kernel or rootfs, you have to specify the environment variables CROSVM_CARGO_TEST_KERNEL_IMAGE and CROSVM_CARGO_TEST_ROOTFS_IMAGE to point to the right files and then run cargo test.

With use_local_build.sh script, e2e_tests can be executed with custom kernel/rootfs as follows:

$ cd /path/to/crosvm
$ cd e2e_tests
$ source guest_under_test/use_local_build.sh
$ cargo test

Unsetting the variables will bring back you to the original behavior.

unset CROSVM_CARGO_TEST_KERNEL_IMAGE
unset CROSVM_CARGO_TEST_ROOTFS_IMAGE

Note: The custom images cannot be used with tools/run_tests.

Uploading prebuilts

Note: Only Googlers with access to the crosvm-testing cloud storage bin can upload prebuilts.

To upload the modified rootfs, you will have to uprev the PREBUILT_VERSION variable in:

./guest_under_test/PREBUILT_VERSION

and request a permission to become a member of the crosvm-policy-uploader group.

Then run the upload script to build and upload the new prebuilts.

# Install QEMU-user-static to build aarch64 images
$ sudo apt install binfmt-support qemu-user-static
# Register binfmt_misc entries
$ docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
# Build and upload the new artifacts
$ ./guest_under_test/upload_prebuilts.sh

Never try to modify an existing prebuilt as the new images may break tests in older versions.
