Elie Kheirallah c3a170e926 e2e_tests: Add Suspend/Resume related tests. 
Add snapshot/restore tests for the VM.
This test currently suspends the VM, then sends a command to it.
This command is stored in the buffer of the serial device.
A snapshot is taken with the command stored.
The device is resumed, which then runs the command.
A restore is triggered using the image taken earlier, which then runs
the image again.

This test will be developed to include more VM changes as more devices
get snapshot.

Crosvm End to End 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

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. Never try to modify an existing prebuilt as the new images may break tests in older versions.
