The work on virtio endianness unveiled the need to add new properties
to VirtIODevice and be able to migrate without breaking compatibility.
There was a similar concern with the introduction of a VirtIODevice.broken
property.
This patch set is a tentative to address the issue, following a suggestion
from Alex:
- patches 1 to 7 adds optional subsections in the virtio migration stream
- patch 8 belongs to the virtio endianness serie, it is sent as an example
Thanks for your comments.
