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.
