Hi
Executive Summary
-
This series of patches fix migration with lots of memory. With them stalls
are removed, and we honored max_dowtime.
I also add infrastructure to measure what is happening during migration
(#define DEBUG_MIGRATION and DEBUG_SAVEVM).

cheking each 64 pages is a random magic number as good as any other.
We don't want to test too many times, but on the other hand,
qemu_get_clock_ns() is not so expensive either.

Yes, at heart it is just a somewhat more expensive access to
pthread_self()->some_array[key].
BTW, this is all only theoretical. This is in the KVM io thread code
which is already highly unportable.
