[Qemu-devel] [PATCH v5 0/6] postcopy (& 1 test) patch for 2.7

["Dr. David Alan Gilbert (git)" <dgilbert@redhat.com>]

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

Hi,
  This is a small set of postcopy changes, the largest of which
is an x86 test for postcopy.

Andrea's libqtest change came about from running my test under very heavy
load.

The test includes a self contained migration workload that rapidly changes
RAM in a predictable fashion allowing us to end up in postcopy mode and
also to be able to check the contents of RAM.

  Note this sometimes fails on Linux kernels 4.5 (and current 4.6) which
  have a KVM+THP bug. Use this fix:
     https://lists.gnu.org/archive/html/qemu-devel/2016-04/msg04028.html

v5:
  Swing sys/ #include's into the ifdef __linux__ on the postcopy test

v4:
  Add a patch to fail migrate-set-capability when turning on postcopy if we
  don't have the kernel support.

v3:
  Change all the test asserts to be g_assert macros (Marcel's suggestion)

v2:
  Split 'Add stats...' into two (Eric's comment)
  Test:
      Survive qmp events landing when we're expecting a response from the
      command (qmp/libqtest doesn't help in that)
      Fix a race where we'd start postcopy early

Dave
