Subject: [Qemu-devel] [PATCH 0/2] Migration/postcopy disallow huge pages
Date: Thu, 29 Sep 2016 20:09:36 +0100 [thread overview]
Message-ID: <1475176178-4873-1-git-send-email-dgilbert@redhat.com> (raw)
From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>
We've not got support for huge pages in postcopy yet, and it
will error when it tries to use the userfaultfd on the hugepage,
however the kernel is going to gain support for userfault
so make sure we fail with a nice error on the new kernel
until we figure out how to add support.
