redirect QEMU window output to terminal running qemu

Question

Im trying to debug the boot sequence of a linux kernel with qemu, the command i\'m running is:

  qemu -serial stdio -kernel  -hda 


        

Answer 1

1. remove -serial stdio parameter
2. add -nographic parameter
3. and change the kernel parameter terminal = ttyS0 to console=ttyS0. This should do the trick.

qemu -nographic -kernel ./bzImage -hda ./image.hda -append root=/dev/sda console=ttyS0

You may want to check the script I use for kernel development: https://github.com/arapov/wrap-qemukvm (it's not very "production", but you can find useful qemu cli parameters there)
