Chaitanya,
First, please stop top posting. Email is like a conversation, and simply makes more sense if you go to the end, just like reading a conversation. DO delete irrelevant stuff.

This is the exact scenario of my machine. i am running the cent os under my virtual box and i have made a network bridge to that VBOX
So, what's the host o/s, Windows?
so from my machine i connect to the VBOX using the Xshell.
What are you using, putty?
and by the way i am new to linux and this is my test machine so that i do some testing.
So READ UP on Linux/Unix.
this is the F reason i am using the root user.
DON'T. Either use root only to do maintenance, or just use sudo to do that. Do *not* test as a root user, except for things only root can do.
what ever os is it i dont think logging in as root user will crash the system.
It won't. However, if you're exposed to the 'Net, you are begging anyone who finds a way to break in to take over your system. Also, doing things as root, esp. if you don't know what you're doing, is a wonderful way to destroy it. Think "format c:/".
regarding the halt command i used it to check what this command will do and this one i have done from the F manual only.
I have no idea what the "F manual" is. From the command line, prompt> man halt
Linux, unlike Windows, comes with man pages for almost all commands.
but now my VBOX machine crashed.
CentOS crashed, or the VBOX? <snip>
