I'm not sure I'm understanding.

You're saying, that, e.g., the migration of a VM between, for instance:

- a Xen 4.11 host, booted without any sched=, and hence running Credit,
  and another Xen 4.11 host, booted with sched=credit2,

should fail _while_ :

- a migration between a Xen 4.11 host, booted without any sched=, and 
  hence using Credit, and a Xen 4.12 host, booted without any sched=, 
  and hence using Credit2 (if we switch),

should succeed ?
