Hi,
I think it will receive them after migration, since the command ring
was stored.
Our confusion here is because you think there is still seemless migration.
Unfortunately
it doesn't work right now, unless you plan to fix it the only form of migration
right
now is switch-host, and for that those commands will be lost, the new
connection will receive
images for each surface. If you treat the client as seemless you are completely
right.
The spice server needs this too so it can render the surfaces correctly
before sending the surface images to the client (or send the old
surfaces and the commands on top of that).
That is one difference between qemu migration and S3 state: For qemu
migration it is no problem to have unprocessed commands in the rings,
they will simply be processed once the spice server state is restored.
When the guest driver restores the state when it comes back from S3 it
needs the command rings to do so, thats why they must be flushed before
entering S3 ...
cheers,
Gerd
