[CentOS] migrating files for centos virtualization, virtual disk no longer boots.

I am playing with virtualization on centos 5.
I took my old redhat 7 disks and created a 10GIG virtual disk, I
installed redhat 7.
Now I am trying to get the EXACT image copied off of my actual redhat 7 disk
so that I know it is the same (including all patches, updates and OTHER
things I did to it that I
have forgotten about).
I booted the redhat 7 image just fine at this point. I also copied it
for backup so I dont have to install again.
So on my centos 5 box I mounted the image with a loop command.
mount -t ext3 -o loop,offset=32256 redhat7.img /mnt/image
This works fine.
Then I logged into the redhat 7 system and executed the command
tar --exclude ./proc --exclude ./mnt --exclude ./sys --exclude ./dev
-cvf - . | ssh root at 192.168.1.8 "( cd /mnt/image ; tar xvpf -)"
Where 192.168.1.8 is my centos 5 box and /mnt/image the mounted image.
The copy seems to go fine. But after I do this when I try to virtualize
the redhat7 image it stops at:
When I copy the second image back on top of the first image it then
boots again. So glad I made that copy
of the image file.
What is happening with the tar command that is messing up grub and
keeping it from booting?
