Which method allows users to manage VMs in Huawei FusionCompute?

The method that allows users to manage virtual machines (VMs) in Huawei FusionCompute by logging into the VM directly is correct because it highlights one of the fundamental ways users interact with virtualized environments. By logging directly into the VM, users can perform various administrative tasks, configure the operating system, install applications, and manage resources as if they were working on a physical machine. This approach gives administrators a hands-on way to access the VM's environment, facilitating more straightforward management compared to alternative methods that might require additional steps or have limitations in functionality.

While managing VMs through command-line interfaces or graphical interfaces is possible, direct access to the operating system of the VM provides a more comprehensive and immediate way to manage the virtualized resources and accomplish tasks within that specific VM. Other listed methods might not provide the same level of access or flexibility required for certain management operations.
