It would help to have a migration wiki page or document that explains
the implications of migration on QEMU code - what to look out for in
device emulation code.

Although regular QEMU contributors may know the background on
migration/save/load, it would be not only helpful for new contributors
but also a good refresher for those of us who have picked up the
assumptions around migration piecewise.

I think a good document would raise migration awareness and help us
review new patches with an eye towards correct migration behavior.

The rules need to be laid down by someone who understands migration
quite well.
