Which technical description of CPU QoS in Huawei FusionCompute is incorrect?

The technical description of CPU Quality of Service (QoS) in Huawei FusionCompute highlights several key concepts that manage CPU resource allocation for virtual machines. The concept of "reservation" is critical as it guarantees a minimum level of computational resources for a virtual machine, ensuring that it always has access to a specified amount of CPU power regardless of other demands on the system. This helps maintain performance for critical applications.

The term "shares" relates to the prioritization of CPU access among multiple virtual machines by assigning a relative weight to each. This means that when CPU resources are contended, those with higher shares will receive more resources compared to those with lower shares, which supports fair usage of the CPU resources according to configured priorities.

When it comes to "limit," it specifically defines the maximum CPU resources that a virtual machine can utilize, not the maximum number of hosts. By setting limits, administrators can prevent any single virtual machine from consuming disproportionate amounts of CPU, which helps maintain overall system stability.

The process of adjusting "Reservation," "Share," and "Limit" together facilitates effective control over CPU resources in a virtualized environment, allowing administrators to optimize performance based on their specific workload requirements.

Thus, option "C" is indeed incorrect because "Limit"
