Re: [Xen-users] still checksum errors with xen-3.0-testing.hg

It would really help us if those of you who were having
problems and needed to use ethtool to turn offload off,
could try latest bits without doing that.

If you are still experiencing problems and turning offload
off still is a workaround, please let us know!

Without ethtool I still get checksum errors. I'm using changeset
9646:a8da66acde0c from xen-3.0-testing.hg  While not the very
latest changeset I do think (judging from the changelog) that
this includes all checksum offload patches.

Thanks for the problem report, Peter. Yep, so you
are using the recently added PCI passthrough stuff?

We have not yet added any tests for that environment
or looked into it yet. Would be good to add that case
to an xm-test configuration. Will let you know once
we get to that one.

At the moment, our assumption has been that the physical
NICs are in dom0. There is probably other stuff to shake
out in driver domain support.


My bridges are connected to dummy devices btw (real NICs are
connected in domU's), maybe this is unusual? Some systeminfo
at the end of this mail

Cheers, Peter
