CentOS - Oct 2007 - Taking file from pyhsical disk to new virtual disk

Hi

I am playing with virtualization on centos 5.
I have an old redhat 7 system I still need so I want to virtualize it.
I found the old disk, installed in the virtual environment but found
I had done some additions WAY back.
I want to be sure my virtual system is exactly the same as the ACTUAL 
system.

Do I use cpio on the actual system to grab everything and then put that 
back on the
virtual system?

What would the format of the command be to grab it and extract it? I 
have never used cpio and dont
want to screw something up.

Is there a better way?

I'm more "tar" adept !
Here is the tar command :

# cd /src
# tar cf - . | ( cd /dst ; tar tvpf - )
This is just a try that display all file it will copy.
Now I copy for real
# tar cf - . | ( cd /dst ; tar xvpf - )
To copy through ssh on a remote machine
 # tar cf - . | ssh root at host "( cd /dst ; tar xvpf - )"
bu scp is fine too

To avoid copy of /proc and other anoying file system you can use
--except ./proc  --except ./sys .......
or better use -l to copy only /src and not other mounted filesystem
then you have to copy /boot and other data partition the same way.

cpio require you to use a filesysteme walker like find to generate the
list of file you wan to  copy.
Something like :
# find . | cpio ???? | (cd /dst ; cpio ??? )
