Subject: [Qemu-devel] [PATCH v2 6/7] vfio: abort if an emulated iommu is used
Date: Tue, 30 Oct 2012 13:47:49 +0200 [thread overview]
Message-ID: <1351597670-23031-7-git-send-email-avi@redhat.com> (raw)
In-Reply-To: <1351597670-23031-1-git-send-email-avi@redhat.com>
vfio doesn't support guest iommus yet, indicate it to the user
by gently depositing a core on their disk.
