Sure, but then this means that, in the restore path, we should query
the scheduler which is in use on the host.
If it is the same one that we also see in the migration stream, we try
to set the parameters. If it is a different one, we skip the setparam
all together (which is basically what Juergen is suggesting later in
the thread, AFAICT).
I don't think I've ever worked on migration, but I can try to look into
fixing this (tomorrow).
Regards,
Dario
