I don't see any obvious problems in the Xenoprof output.  Anyone with

You'll never get good throughput either from a NE2000 nor from a pcnet32
That was a suspicion of mine, but I wasn't sure. I wonder if qemu-dm could emulate another adapter (if so, which one would be best?) or do we just punt and go for para-virt drivers.
