Hikaru Nishida 917e1f4641 guest_under_testing: uprev PREBUILT_VERSION It looks like r13 of the prebuilt uploaded does not include the change made in https://crrev.com/c/5190792 . This CL updates the prebuilt with the CL as well as the updates made so far.

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.
