Aiming at the problems of the traditional desktop, a virtual desktop solution based on the SPICE framework and Openstack platform is proposed. The server cluster is built with KVM virtualization technology, and the SPICE protocol connects the client and the server to transmit data. This study analyzes the current mainstream transmission protocol and the key factors that affect the performance of the desktop, and introduces the realization process of the virtual desktop in detail. The test proves that the virtual desktop has good user experience and practicality, and it effectively solves the problems of the traditional desktop in management and cost.
