Since kernel v6.3 the vsock packet is not split over two descriptors and
is instead included in a single one.
Therefore, we currently decide the specific method of obtaining
BufWrapper based on the length of descriptor.

Introduction
Dragonball Sandbox is a light-weight virtual machine manager (VMM) based on Linux Kernel-based Virtual Machine (KVM),
which is optimized for container workloads with:
- container image management and acceleration service
- flexible and high-performance virtual device drivers
- low CPU and memory overhead
- minimal startup time
- optimized concurrent startup speed
Dragonball Sandbox aims to provide a simple solution for the Kata Containers community. It is integrated into Kata 3.0
runtime as a built-in VMM and gives users an out-of-the-box Kata Containers experience without complex environment setup
and configuration process.

Acknowledgement
Part of the code is based on the Cloud Hypervisor project, crosvm project and Firecracker project. They are all rust written virtual machine managers with advantages on safety and security.
Dragonball sandbox is designed to be a VMM that is customized for Kata Containers and we will focus on optimizing container workloads for Kata ecosystem. The focus on the Kata community is what differentiates us from other rust written virtual machines.
