I think it's difficult to do such actions in program or script.

In this way, the guest don't know the host IP except I send a message to
guest when qemu run, Beause I may run qemu in different computer. When
read the document, I can't find any way to send a message to guest in
the command line or script.

The best way I think is get the output of guest when it booting. I only
find the option of redirect the guest output use -serial dev. But I
can't read the output when use -serial pty. Is any other ways?

thank you!
