Dennis Kempin 3f63661afc Run integration_tests by calling crosvm binary
Instead of instanciating crosvm directly, we can start the binary as
a sub-process.
This includes parsing of crosvm options in the tests, and makes the
test cases closer to real-world usage.

To make make this possible, we need to make sure that the crosvm binary
is uploaded to the VM before running the test, which is done by the
sync_so script, which is baked into the builder container.
We prevent future container re-builds for just maintaining the script,
I have removed them from the container, and call the scripts from the
local source directly.

The test runner is also updated to ensure all package binaries are
built (currently only tests are built).

Crosvm Integration 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.

Running with locally built kernel/rootfs

If the test needs to run offline, or you want to make changes to the kernel or rootfs, you have to specify the environment variables CROSVM_CARGO_TEST_KERNEL_BINARY and CROSVM_CARGO_TEST_ROOTFS_IMAGE to point to the right files.

The use_local_build.sh script does this for you:

$ source guest_under_test/use_local_build.sh

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
  • src/third_party/chromiumos-overlay/chromeos-base/crosvm/crosvm-9999.ebuild

Then run the upload script to build and upload the new prebuilts. Never try to modify an existing prebuilt as the new images may break tests in older versions.
