Subject: [Qemu-devel] [PATCH v2 0/5] postcopy (& 1 test) patch for 2.7
Date: Fri, 29 Apr 2016 15:47:38 +0100	[thread overview]
Message-ID: <1461941263-9523-1-git-send-email-dgilbert@redhat.com> (raw)

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

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
