[Xen-devel] question about DomU kernel loading


I was trying to check the integrity the kernel of any DomU. 

Here is my experiment:

1. parse xenU kernel image, extract ".text" section from the image.
2. dump the domU memory from the dsi.v_start upto the size of ".text" section.
3. compare the results from step 1 and step 2.

I found that the majority of the code are the same, but still about 500 bytes 
are different between these two in various locations.

Could anyone tell me why are not they the same and what made the difference?
