By the way, pci currently has cmask,
which performs checking on load, making sure
that load does not modify a constant field in config space,
which can't change as a result of guest actions.
If it does - migration fails.
This is IMO much better and more robust than
simply hoping that there are no bugs or that
developers remember to increment a version
number each time they change some field.
I think it's pretty important to keep this
feature, and maybe add something similar
to other devices.
How will VMState support this?
