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_tests2 --dut=vm -E 'rdeps(e2e_tests)'
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
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.
