The virtual console is used by the operating system as a console for various processes, such as installations, recovery from crashes, and performing boot-related operations. 操作系统可以使用虚拟控制台作为各种处理工作(如安装工作、对崩溃故障进行的恢复工作,以及执行启动相关的操作)的控制台。
Switch to the first virtual console ( Ctrl + Alt + F1 ) to see the live system messages; this should tell you where the problem is. 切换到第一个虚拟控制台(Ctrl+Alt+F1),查看系统消息;这样可以知道哪里出了问题。
Through comparative analysis found that the method that use the virtual interface instead of the physical console for the simulation research, could save money and reduce the development cycle, and perfect compliance with system requirements. 通过对比分析发现用虚拟界面代替实物控制台进行仿真研究,即可节省费用,又可缩短研制周期,并很好符合仿真系统需求。
