Example Embodiment
[0028] The embodiments of the present invention will be described in detail below with reference to the drawings: this embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation modes and specific operation procedures are given, but the protection scope of the present invention is not limited to the following Mentioned examples.
[0029] figure 1 It is the scheduling model framework of the present invention. The present invention adds two new modules to the original scheduling model, namely an interrupt monitoring module and a CPU monitoring module. The interrupt monitoring module intercepts the information transmitted in the event channel, and counts the interrupt frequency of each virtual machine according to the interrupt number and the id of the virtual machine. The CPU monitoring module monitors the scheduling information of all virtual machines and calculates the CPU usage of the virtual machines in a certain pe...
