Cherrybomb Primitives for Firecracker

⚡ High-performance patches for Firecracker microVMs, contributed by the HYPR Project team. These primitives unlock capabilities normally unavailable in vanilla Firecracker, enabling experimentation with unikernels, memory snapshot booting, and ultra-fast inter-VM communication.

Features

Applying these patches to a standard Firecracker build unlocks:

1. Direct ELF Boot Boot statically linked ELF binaries directly, skipping the full kernel. Perfect for unikernels and specialized workloads.

2. Memory Image Boot Launch a microVM from a pre-loaded memory snapshot, enabling sub-10ms "hot starts" and fast iteration.

3. IVSHMEM Device Support High-performance shared-memory interface for communication between host and guests, or between multiple guests.
