[Qemu-devel] [PULL 2/6] migration: do not transfer ram during bulk storage migration

[Dr. David Alan Gilbert (git)]

From: Peter Lieven <pl@kamp.de>

this patch makes the bulk phase of a block migration to take
place before we start transferring ram. As the bulk block migration
can take a long time its pointless to transfer ram during that phase.

this actually limits (as the original commit mesage suggests) the
number of I/O buffers that can be allocated and not the number
of parallel (inflight) I/O requests.

[Dr. David Alan Gilbert (git)]

From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>

In 2c9bb29703c I added a migration test that purposely fails;
unfortunately it prints a copy of the failure message to stderr
which makes the output a bit messy.

Hide stderr for that test.
