Date: Thu, 20 Sep 2012 01:12:54 -0000 From: Anthony PERARD X-Patchwork-Id: 185378 Message-Id: <1348139574-23324-6-git-send-email-anthony.perard@citrix.com> To: QEMU-devel Cc: Anthony Liguori , Luiz Capitulino , Stefano Stabellini , Avi Kivity , Anthony PERARD , Xen Devel If the call to xc_hvm_track_dirty_vram() fails, then we set dirtybit on all the video ram. This case happens during migration, but we don't need a special case for live migration with patch.
