Which description about clusters, hosts, and virtual machines in Huawei FusionCompute is incorrect?

The statement that virtual machines can be migrated across clusters is incorrect because, in Huawei FusionCompute, virtual machines are typically confined to a specific cluster. This restriction is primarily due to the dependency of virtual machines on the resources and configurations provided by their host cluster. Each cluster is considered a separate logical entity that manages its own virtual machines, and moving a virtual machine to another cluster involves a more complex process than simple migration, such as preserving its network settings and storage access, which may differ between clusters.

In contrast, the other descriptions reflect accurate characteristics of clusters, hosts, and virtual machines in Huawei FusionCompute. For instance, the determination of whether hosts belong to the same cluster often relies on the use of unified shared storage, allowing multiple hosts to access the same storage pool seamlessly. Additionally, a cluster consists of multiple hosts along with their respective storage and network resources, highlighting the interconnectedness of these components. Lastly, while virtual machine migration across clusters is not standard practice, it is indeed possible to move hosts between different clusters under the right configurations and administrative settings, indicating the flexibility of host management within the infrastructure.
