What is not a requirement for implementing HA (High Availability) for a compute node in Huawei FusionCompute?

The implementation of High Availability (HA) for a compute node in Huawei FusionCompute does not require that the virtual machine must be bound to the host. This is because HA is focused on ensuring that virtual machines remain available even in the event of a hardware or software failure. Binding a virtual machine to a specific host can actually limit its mobility and ability to failover to another host, which contradicts the core principle of HA.

In an HA setup, the system is designed to automatically restart virtual machines on another node in the event of a failure, helping to maintain availability. The other conditions mentioned are essential for HA implementation: using shared data storage ensures that all nodes in the cluster can access the necessary data, enabling continued operation of the VMs regardless of which node they run on; enabling HA at the cluster level is crucial for orchestrating the failover process; and having VMs within the same IP network segment ensures seamless network connectivity and communication during the failover process.
