In Huawei FusionCompute architecture, which component is part of the Host Machine role?

In the Huawei FusionCompute architecture, the component that is part of the Host Machine role is the Compute Node. The Compute Node serves as the physical server or machine that hosts virtual machines and operates the essential resources for compute tasks within the cloud environment. It is responsible for running the KVM (Kernel-based Virtual Machine) hypervisor, which is the software layer that enables virtualization by allowing multiple virtual machines to run on the same physical hardware.

The Compute Node plays a critical role in providing the actual processing power, memory, and networking resources required by the virtual machines, all of which are essential for effectively executing workloads in a virtualized environment. It serves as the backbone of the virtualization ecosystem, making it a fundamental component of the Host Machine role within the FusionCompute architecture.

In contrast, the Virtual Resource Manager is responsible for managing resources across multiple Compute Nodes but does not directly reside on a single Host Machine. The KVM hypervisor, while crucial for enabling virtualization, operates at the level of the Compute Node rather than being an independent component of the Host Machine role. The Storage Access Module facilitates connectivity to storage resources, but like the Virtual Resource Manager, it does not constitute a part of the Host Machine itself.
