Method for switch virtualization, computer equipment and medium

The invention relates to the technical field of computers and provides a method for switch virtualization, computer equipment and a medium. The method includes running a master operating system through a master processor of the data processing unit, and simulating generation of a switch controller and a virtual device controller and running of a slave operating system through a slave processor of the data processing unit, the startup of the slave operating system being independent of the startup of the master operating system, and the startup of the slave operating system being independent of the startup of the virtual device controller. The starting time of the slave operating system is shorter than that of the master operating system; and through the switch controller and the virtual device controller, simulating generation of a downlink port of the first switch and the hooked virtual device, executing a control plane operation associated with input/output virtualization of the first switch by using the sla
