Hey Luciano,
Thanks for the information, while this does solve the problem. This
feels more like a hack, rather than a permanent fix. Is this a bug in
Xen, or is this something we should expect from now ?
Thanks!

Thanks for this, will this also apply to all VMs as well? I
noticed I'm
also having the same problem in the DomUs as well now - I can
resolve it by
consoling into them, and using this: ethtool -K eth0 tx off
You'll have to install the script on the DomUs also.

Hi,
It is a bug in Xen. In a few places in the network stack, there are some
checksums made. Somewhere along the way an extra checksum is taken where
it shouldn't. So the checksum doesn't match the packet anymore. On
Windows clients, you'll notice this because you'll see dropped packets.
On linux, you will nearly see it, because your linux box will try to use
the packets even when the checksums do not match.
Can you tell me which version of Xen you are using? I've seen this on
Xen 3.1 and I'm hoping that it is solved in Xen 3.2
Jeroen
