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:
|
|
|
|
|
2022-01-25 23:14:43 +00:00
|
|
|
`$ 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.
|

|
|
|
|
2022-01-25 23:14:43 +00:00
|
|
|
To upload the modified rootfs, you will have to uprev the `PREBUILT_VERSION` variable in:
|
2020-11-10 17:34:56 +00:00
|
|
|
|
|
|
|
- `./guest_under_test/PREBUILT_VERSION`
|
|
|
|
- `src/third_party/chromiumos-overlay/chromeos-base/crosvm/crosvm-9999.ebuild`
|
|
|
|
|
2022-01-25 23:14:43 +00:00
|
|
|
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.
