[Qemu-devel] [PATCH RFC 0/8] virtio: migrate new properties

[Greg Kurz <gkurz@linux.vnet.ibm.com>]

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.
