= Solution - Separate configuration from compat hints =
As I suggested before:
- Allow the VM manager to dump compat hints; this would be an opaque
file format, more like the savevm format than a config file
How is compat hints different from a device tree?
In my mind, that's what compat hints is. I don't see another sane way
to implement it.
A device tree with a different purpose than a config file.
In its simplest form it could be a device tree with a version number for
each device[1].
I think the point is that you don't need version numbers if you have a
proper device tree. NB the device tree contains no host configuration
information.

The other obvious piece to add to it would be PCI addresses, so that
even if you remove a device, the addresses assigned to existing devices
don't change.
Cheers,
Mark.
[1] - Adding such a per-device version number to the config file would
solve problem (2)
