[PATCH v2 0/4] Fix "virtio-gpu: fix scanout migration post-load"

[marcandre . lureau]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Hi,

The aforementioned patch breaks virtio-gpu device migrations for versions
pre-9.0/9.0, both forwards and backwards. Versioning of `VMS_STRUCT` is more
complex than it may initially appear, as evidenced in the problematic commit
dfcf74fa68c ("virtio-gpu: fix scanout migration post-load").

v2:
 - use a manual version field test (instead of the more complex struct variant)

Marc-André Lureau (3):
  migration: add "exists" info to load-state-field trace
  migration: fix a typo
  virtio-gpu: add x-vmstate-version

Peter Xu (1):
  virtio-gpu: fix v2 migration
