Which statement is incorrect regarding NUMA's description?

The statement identifying Host NUMA as primarily providing a CPU load balancing mechanism to resolve VM performance bottlenecks due to imbalanced CPU resource allocation is incorrect. Host NUMA (Non-Uniform Memory Access) refers to the organization of memory in nodes, where each node has its own local memory and can access the memory of other nodes.

In this context, while CPU load balancing is a relevant consideration in virtualization environments, it is not the defining characteristic of Host NUMA. Instead, Host NUMA's primary role is to facilitate efficient memory access for virtual machines (VMs) by ensuring that they can access their local node's memory more quickly than that of remote nodes. This is crucial for minimizing memory access latency, thereby improving VM performance.

The other statements accurately reflect aspects of NUMA technology. Guest NUMA ensures that guest operating systems can identify their own NUMA architecture for optimized application performance. The technology facilitates performance improvement by harmonizing the access speeds of memory within the same node and mitigating the latency of accessing memory from other nodes. Furthermore, Host NUMA indeed plays a vital role in guaranteeing that VMs have access to local physical memory, contributing to reduced latency and enhanced performance.

Thus, the mischaracterization of Host NUMA's primary
