All,
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@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: GRUB
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?
Thanks,
Jerry
