Fedora12-1
This looks fine, but what is 'Fedora12-1'? It's presumably a raw disk
file. What is its size? What command did you use to create the file?
I created Fedora12-1 using this command
dd if=/dev/zero of=Fedora12-1 bs=1024k count=2000
it is 2gb disk.
Also please show the full messages that virt-resize printed when you
ran the command.
Debug messages show like this:

This doesn't matter.
Also make sure you're booting with the new image file, not the old one ...
Yes i am sure i am booting with new Image file.
One more thing i am able to boot the new image but not able to mount it.
Rich.
Thanks
