Good news is I am able to reproduce this with my 32-bit NIC with 3.2 domU:
[ 771.896140] SWIOTLB is 11% full
[ 776.896116] 0 [e1000 0000:00:00.0] bounce: from:222028(slow:0)to:2 map:222037 unmap:227220 sync:0
[ 776.896126] 1 [e1000 0000:00:00.0] bounce: from:0(slow:0)to:5188 map:5188 unmap:0 sync:0
[ 776.896133] 3 [e1000 0000:00:00.0] bounce: from:0(slow:0)to:1 map:1 unmap:0 sync:0
but interestingly enough, if I boot the guest as the first one I do not get these bounce
requests. I will shortly bootup a Xen-O-Linux kernel and see if I get these same
numbers.
