云管理平台和虚拟机终端用户间的通信一般采用代理软件或插件，便捷性和抗干扰能力较低。针对该问题，利用基于内核的虚拟机( KVM)虚拟桌面，提出一种云服务提供节点(虚拟机所在物理主机)和虚拟机终端用户之间双向交互的透明消息通道设计方案。在云管理平台中建立消息控制端，用于接收和处理服务节点发往虚拟机终端用户的消息，并将消息转换为图像，使图像内容以位图像素数据格式的方式读出到特定文件中，作为消息发送模块的消息来源。通过修改KVM虚拟化平台中Qemu-KVM集成的VNC Server端源码，在源码中添加消息发送模块和反馈接收模块，将消息集成融入到虚拟机桌面图像中，并对VNC Client远程终端反馈的消息进行处理，从而得到一条对虚拟机自身系统透明的，可在云平台和终端用户间双向交互的消息通道。实验结果验证了该设计方案的可行性。

Cloud management platform and end-users of virtual machine generally use proxy software or plug-ins to communicate with each other,but the convenience and anti-jamming capabilities of this method is poor. Aiming at this problem ,this paper proposes a design scheme for transparent message channel between the node provided by cloud service ( the physical host that virtual machine lies in) and the end-user of virtual machine based on virtual desktop on Kernel-based Virtual Machine( KVM) . It builds message control terminal in cloud management platform to receive and process messages that service node sends to end-users of virtual machine, and transforms the messages into images, reads the content of images into specified file in the form of bitmap pixel data as the source of message sending module. It adds message sending module and feedback receiving module into source codes by modifying the source code of Virtual Network Computing ( VNC ) server-side integrated by Qemu-KVM of KVM virtualization platform, integrates the messages into desktop image of the virtual machine,and processes the feedback from the remote terminal of VCN client. Then it builds a two-way interactive message channel between the cloud platform and the end-users which is transparent for virtual machine itself. Experimental result verifies that this scheme is feasible.
