基于KVM虚拟机的串口转发器的研究与设计

摘要

For serial and serial number of the limited reusability, extended use of serial peripheral is very important. By introducing the serial and KVM virtual machines, proposed based on the serial port KVM virtual machine to forward the design method that allows for both a serial port on a virtual machine on a different system to provide physical serial port service. Experiments show that: the same physical serial port can be concurrent, so that users have a choice of virtual systems for different services to address the physical limitation of serial peripheral problems.%针对串口个数的有限性和串口的可重用性,扩展串口的外设使用显得尤为重要；通过介绍串口及KVM虚拟机,提出了一种基于KVM虚拟机的串口转发器的设计方法,能够让一个串口同时能为虚拟机上的不同系统提供物理上的串口服务,实验表明:同一个物理串口能够并发的、让用户有选择的为不同的虚拟系统服务,解决了物理串口外设有限性的难题.
