Assumption:

• We want to support a range of devices
• We acknowledge that certain devices are exposed using different kernel APIs (paths, netlink, …)
• We acknowledge that a logical/physical device can consist of multiple kernel level objects (paths, netlinks, …)
• We acknowledge that device plugins could require informations about the pod in order to provide the right resource.

Goal:

• Keep the declarative approach
• iow: DP creates, kubelet allocates
• iow: Prevent side-kubelet

## Another shot at the problem scope

Devices to support

- GPUs
- FPGAs
- Network cards
- Random Number Generators

A VM is defined by three aspects

• Size
• Guest
• Workload

Overview

Components

1. (1) trusted storage connector pod
2. (Many) VM pods connection to storage using shared directory
