Chris has a point there, about checksumming.

I have no problems with the 17.31 kernel on an amd64 domU. And dom0 is running the hardy kernel (-16.xx), also amd64. I'm using debians hypervisor (3.2.0-3~bpo4+2).
And I DO have checksumming offload off (as described using /etc/network/interfaces). It was necessary with previous kernels and I didn't even think about it.

There is a difference between checksum offload on and off. With offload OFF I have a througput (domU->dom0) 18M/s; with offload on it is only 12 (using an 36M file).
From domU to domU (same host) it doesn't matter whether offload is on or off.

But still no BUG.
