5.9.7. Boot the Image and Verify Your Changes

These steps boot the image and allow you to see the changes

  1. Boot the image: Boot the modified image in the QEMU emulator using this command:

         $ runqemu qemux86
                            
  2. Verify the changes: Log into the machine using root with no password and then use the following shell command to scroll through the console's boot output.

         # dmesg | less
                            

    You should see the results of your printk statements as part of the output.
