Abstract: Sometimes you need to log on to the virtual machine through the host hvc0, and sometimes you need to log on to the virtual machine through vnc for management. In this way, you need to have corresponding configurations to ensure that both of them can be output normally. The specific configuration is as follows. Hvc is a virtual console that is introduced by Xen virtualization technology to control
