MIG Support for ACS

### The required feature described as a wish

ACS 4.22 does not detect or enumerate MIG instances created on NVIDIA GPUs. Only vGPU-based slicing is recognized. This blocks environments that rely on MIG for finer-grained, hardware-level GPU partitioning and prevents ACS from scheduling or assigning MIG devices to instances. Support for native MIG discovery and allocation is required

首先追踪 ACS 4.22 当前如何检测和枚举基于 vGPU 的切片，然后审查 NVIDIA MIG 发现和分配的要求。当原生 MIG 实例能够被发现、枚举、调度并分配给实例时，即表示完成。
