Daniel Verkamp 7fd815ed22 crosvm: switch to upstream tempfile crate 
Use the crates.io implementation of tempfile instead of our own version.

Our reimplementation is kept in the tree for now in case of dependencies
outside of the crosvm tree; it can be removed later once those are fully
switched over to the crates.io implementation.

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.
