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)
v3:
- introduce machine_check_version()
- drop the VMSD version, and use machine version field test
v4:
- drop machine_check_version() approach
- property renamed to x-scanout-vmstate-version
Marc-André Lureau (3):
migration: add "exists" info to load-state-field trace
migration: fix a typo
virtio-gpu: fix v2 migration
