To prevent spying on remote console sessions, limit the number of remote console connections that are allowed.

By default, more than one user can connect to a virtual machine remote console session at a time. If more than one user connects to a remote console, the users can observe the operations performed by other remote console users. For example, if a virtual machine administrator logs in to the virtual machine using the remote console, a user without administrator privileges can simultaneously connect to the virtual machine console and observe the administrator's actions.
