Which of the following is not a CPU resources QoS parameter in FusionCompute?

In the context of FusionCompute, CPU resource management is crucial for ensuring that virtual machines (VMs) operate efficiently and fairly share available CPU resources. The establishment of Quality of Service (QoS) parameters is essential for managing these resources effectively.

The correct answer is that "CPU resource reuse" is not considered a QoS parameter. This is because QoS parameters focus on how resources are allocated and prioritized among different VMs. The concepts of CPU share, resource limits, and resource reservations are all fundamentally aimed at controlling and managing CPU resources:

• CPU share of resources involves defining how much CPU time each VM gets relative to others, promoting fairness in resource allocation during contention.

• CPU resource limits cap the maximum amount of CPU resources a VM can utilize, preventing any one VM from monopolizing CPU capacity.

• CPU resource reservation guarantees that a specified amount of CPU resources will always be available to a VM, ensuring performance stability for critical applications.

On the other hand, CPU resource reuse does not fit into the traditional QoS framework, as it doesn’t pertain to the allocation, prioritization, or guarantees of CPU resources among VMs. Reuse typically refers to the act of utilizing previously allocated resources for new tasks but does not constitute a measurable
