What determines the ability to log in to a virtual machine in Huawei FusionCompute?

The ability to log in to a virtual machine in Huawei FusionCompute is primarily determined by the virtual machine's operating system. The operating system is responsible for managing user accounts, authentication, and access control. It dictates how users can log in, whether through a graphical user interface or command line, and it enforces security measures, such as passwords and permissions.

While physical connections, computing resources, and configuration of manager privileges may impact the overall environment, they do not directly govern the login process for a virtual machine. The operating system must be properly configured and running to allow successful login attempts. Hence, understanding the operating system's role in user authentication is crucial for managing and accessing virtual machines effectively.
