In Huawei FusionCompute, when can users increase or decrease the number of vCPUs of a virtual machine?

In Huawei FusionCompute, users can change the number of virtual CPUs (vCPUs) assigned to a virtual machine both when the virtual machine is running and when it is stopped. This capability is part of the flexibility and dynamic resource management features offered by virtualization platforms. When a virtual machine is running, it allows for adjustments to resources such as vCPUs without the need for downtime, enabling better resource allocation based on current workload demands. This dynamic scaling feature is particularly useful in environments that require rapid adaptation to varying workloads.

Moreover, being able to adjust vCPUs while the VM is stopped is standard practice as well, catering to scenarios where a user may want to make substantial resource changes without disrupting service. Therefore, allowing changes in either state (running or stopped) supports operational continuity and performance optimization, making it a robust feature of the Huawei FusionCompute architecture.
