摘要：

Aimed at the needs for scheduling real-time tasks in the environment of open real-time system and embedded system, a scheduling mechanism based on messages has been suggested and applied on the Xen virtual machine, and a Multi-Real-Time-Task model based on VCPU is established. Influence on the real-time scheduling is analyzed and solutions will be given. Experiment results prove that scheduling based on this mechanism works well, since in current experiment environment the response time of compute-intensive real-time task is less than 20us, and the response time of event-driven real-time task is less than 30us, both results are quite stable.
