Intermittent LoadSnapshot integration test and examples failures due to bad rootfs. #418

Closed austinvazquez closed 1 year ago

austinvazquez commented 2 years ago

For testing CreateSnapshot and LoadSnapshot support in the SDK, we started utilizing firecracker's devtool to create a microVM rootfs and SSH key for spinning up microVMs we could run commands inside using SSH.

It would be nice to have these artifacts publicly available via S3 bucket for download compared to building it at runtime.

The load snapshot integration test can sometimes fail with the following:

=== CONT  TestLoadSnapshot

This is a result of a bug in Firecracker's devtool causing the rootfs build to silently fail.
