No init messages display during startup/shutdown
This question is more in the line of how init messages get sent to a console during startup/shutdown. My problem has to do with exporting a VM from AWS to KVM (and a retry on virtual box). I am looking for a understanding on how init messages are sent to a device and what controls them My two servers listed below are Centos. Any help in this understanding would be greatly appreciated. Any additional knowledge on how AWS is modify this would also be appreciated.

I have exported two VM's. Both imports successfully on virtualbox and kvm but one allows you to login (login prompt) and the other never comes to the login prompt. For the VM that allows log in I have edited /default/grub2 and removed silent and added text and regenerated the grub.conf. I also put a exit in the /etc/init.d/netconsole so that it doesn't run. I still dont get any init messages to the console when I reboot. I need to determine how to do this so I can make the changes to a EC2 VM so when I export it again and try to run it in virtualbox and KVM it will list a service that it is getting hung up on. Any help would be greatly appreciated

Thanks

sulogin

sulogin(1M)						  System Administration Commands					       sulogin(1M)

NAME

       sulogin - access single-user mode

SYNOPSIS

       sulogin

DESCRIPTION

       The  sulogin  utility  is  automatically invoked by init when the system is first started. It prompts the user to type the root password to
       enter system maintenance mode (single-user mode) or to type  EOF (typically <CTRL-D>) for normal startup (multi-user mode). The user should
       never directly invoke sulogin.

       The  sulogin utility can prompt the user to enter the root password on a variable number of serial console devices, in addition to the tra-
       ditional console device. See consadm(1M) and msglog(7D) for a description of how to configure a serial device to  display  the  single-user
       login prompt.

FILES

       /etc/default/sulogin    Default value can be set for the following flag:

			       PASSREQ	       Determines if login requires a password. Default is PASSREQ=YES.

       /etc/default/login      Default value can be set for the following flag:

			       SLEEPTIME       If  present,  sets  the number of seconds to wait before login failure is printed to the screen and
					       another login attempt is allowed. Default is 4 seconds. Minimum is 0 seconds. Maximum is 5 seconds.

					       Both su(1M) and login(1) are affected by the value of SLEEPTIME.
