Which of the following descriptions regarding memory reuse in Huawei Fusion Compute is incorrect?

Using memory reuse in Huawei Fusion Compute is designed to optimize resource allocation, particularly when handling virtual machines. The correct choice reflects a common concern regarding performance implications. Memory reuse allows multiple virtual machines to share the same physical memory resources, which can lead to increased efficiency. However, this shared approach might lead to a situation where the performance of virtual machines can be impacted negatively, especially if there are excessive memory allocations leading to contention among virtual machines for the same memory resources.

By enabling memory reuse, administrators can maximize the use of available physical memory, but this approach can introduce overhead as the system manages how the memory is accessed and shared. Performance issues may arise, particularly under heavy load or when running memory-intensive applications, where the separation and retrieval of memory from various virtual machines can lead to latency and reduced efficiency.

Therefore, the assertion that using memory reuse can degrade virtual machine performance accurately reflects the reality of balancing resource optimization against individual VM performance, making it the correct answer concerning the question of incorrect descriptions regarding memory reuse.
