Interesting; As a test could you try removing the cdrom entry (I doubt that'll
help but it's worth a go).
Also, is it possible for you to try a bisection?
If I was to guess, I'd bet it's something relating to the pflash, but I
don't know; it's unfortunate the block migration doesn't say what it got
upset by.
Are there no errors on the source side?
Assuming there are no errors on the source side, I'd have to suggest
taking a printf to migration/block.c block_load to find out which exit
it's falling out of in there (at least I think that's what would cause
that error)
