Method for dynamically distributing cloud desktops

The invention relates to the technical field of cloud computing, in particular to a method for dynamically distributing desktops based on a cloud operating system platform. In the method for dynamically distributing cloud desktops, terminals are identified by the unique T__ID, a terminal management system automatically distributes corresponding virtual machines to the terminals according to the T__ID when the terminal is started, and the terminal automatically logs in the virtual machines according to IP (internet protocol), user names and passwords and the like of the virtual machines distributed by the terminal management system. The foreground terminals and the background virtual machines correspond one by one, and when the terminals are closed normally, the corresponding virtual machines of the terminals stop running. Meanwhile, the terminal management system scans states of various registered terminals within the system range in real time, when the registered terminals are found to be closed abnormally, the corresponding virtual machines of the registered terminals can be set to be dormant by the terminal management system, so that the virtual machine can stop running. The method for dynamically distributing desktops realizes automatic and dynamic distribution of cloud terminals effectively and can be applied to managements of the cloud terminals and the virtual machines.
