Is anyone looking at these? Apparently this hasn't passed for 23 months:
http://xenbits.xen.org/gitweb/?p=linux-pvops.git;a=shortlog;h=refs/heads/tested/linux-linus

Looking through the recent failures this migration one seems quite
common but there seem to be a few others, search for "[linux-linux
test]" in http://lists.xen.org/archives/html/xen-devel/2014-03/ for some
examples.

The particular failure here is
http://www.chiark.greenend.org.uk/~xensrcts/logs/25478/test-amd64-i386-pair/info.html
 and the console logs 
http://www.chiark.greenend.org.uk/~xensrcts/logs/25478/test-amd64-i386-pair/serial-gall-mite.log
  are full of
        Mar 14 13:24:27.592641 [ 1010.742462] mptsas 0000:03:00.0: swiotlb 
buffer is full

The migration itself times out after 5 minutes or so (for a 512M guest)
