I have tried the method but it looks still can't work, there is no "hvc0" device file in my "/dev" directory,
is that the root cause?

parameter is present in the VM config file) and a PV console.
However the default first console is the emulated serial with libxl (see
libxl__primary_console_find), that is what you get when you execute "xl
console" without -t.
But if you edit inittab to spawn a getty on hvc0 and then execute "xl
console -t pv" you should get access to the PV console.
