Re: migration with exec giving truncated images

[Uri Lublin <uril-atKUWr5tajBWk0Htik3J/w@public.gmane.org>]

Thanks for the patches.

There is still the mystery of different file sizes for different 
migration-exec commands, all files are "valid saved image".
It seems to me that some unmodified pages are being marked as dirty, and 
are being saved twice (and later loaded twice).
I'm still chasing that.
