[PATCH v2 0/2] Enfore multifd and postcopy preempt setting

[Wei Wang <wei.w.wang@intel.com>]

Setting the cap/params of multifd and postcopy preempt is expected
to be done before incoming starts, as the number of multifd channels or
postcopy ram channels is used by qemu_start_incoming_migration (to
listen on the number of pending connections).

Enfocre the cap/params of multifd and postcopy preempt to be set
before incoming. If not, disable the feature and return with error
messages to remind users to adjust the commands. Fix the
qtest/migration-test to do so.

Wei Wang (2):
  migration: enfocre multifd and postcopy preempt to be set before
    incoming
  qtest/migration-tests.c: use "-incoming defer" for postcopy tests
