Firecracker v0.7.0 release Added * Rate limiting functionality allows specifying an initial one time burst size. * Firecracker can now boot from an arbitrary boot partition by specifying its unique id in the driver's API call. * Block device rescan is triggered via a PUT /actions with the drive ID in the action body's payload field and the action_type field set to BlockDeviceRescan. Changed * Removed `noapic` from the default guest kernel command line. * The action_id parameter is no longer required for synchronous PUT requests to /actions. * PUT requests are no longer allowed on /drives resources after the guest has booted. Fixed * Fixed guest instance kernel loader to accelerate vCPUs launch and consequently guest kernel boot. * Fixed network emulation to improve IO performance.
