[Qemu-devel] [PATCH v2 0/6] migration: objectify MigrationState

[Peter Xu <peterx@redhat.com>]

v2
- (I didn't add Juan's r-b since I touched the patches)
- remove once parameter in migrate_get_current() since not needed
- add one more patch to export register_compat_prop(), then use it in
  the following patches in xen_init().

I picked this topic out as suggested by Juan. Also I did what Juan has
suggested in previous discussions that I moved lots of global
parameters into MigrationState, and let them be properties. Then we
can use HW_COMPAT_* and "-global migration.xxx=xxx" formular.

Currently register_compat_prop() is exported to be used by xen_init().

If this can be merged and okay, we can move on to convert more things
into properties for migration.

Please review. Thanks.
