In Huawei FusionCompute, which operating system is running on the host when a Linux-based virtual machine is created?

In the context of Huawei FusionCompute, when you create a Linux-based virtual machine, the host operating system that is responsible for managing the virtual machines is CNA, which stands for Cloud Node Agent. This agent is crucial as it enables the host to operate efficiently within the FusionCompute environment, handling communication between the virtualization layer and the management platform.

The CNA is specifically designed to manage the resources and allocate them to the virtual machines running on the host, which can include various operating systems, such as Linux. This ensures that the performance, resource allocation, and monitoring of virtual machines are conducted seamlessly. In this architecture, CNA plays a pivotal role in maintaining the stability and efficiency of the virtualized environment.

Other options do not represent the operating system that runs on the host in this scenario. For instance, while VNA (Virtual Network Adapter) refers to networking aspects and VRM (Virtual Resource Manager) deals with resource management aspects, neither serves as the base operating system for the host where the virtual machines execute. The option denoting a Linux virtual machine does not apply to the host itself but rather identifies the type of VM being created.
