Hi,
Thanks for the reply :) We didn't post to xen-devel because we thought
the project were interesting for xen deployments rather than xen
internals and development. But I'll give it a try anyway. Do you think
the original message we posted on xen-users is well suited for xen-devel
(in exactly the same form)?

Our current development is on 2.6.29, but we also maintain 3 other
versions:
2.6.25
2.6.21
2.6.18
Since we only add a hook in the netdevice rx stack (and everything else
is in our own module), we expect it to apply and work on most kernel
versions.
We have mostly relied on fedora (and they removed dom0 support in their
kernel starting with FC9), so the latest xen patched kernel that we
actually tested is 2.6.21.

Thanks for the tip. The site definitely needs updating and better
instructions.

Yes, we do: http://lisa.ines.ro/mailman/listinfo/lisa-devel
It looks like you know your way around kernels and git. Perhaps the
easiest way to do it is to clone our git tree and try to rebase our
branch on top of whatever xen branch you are testing against.

I hope you are not using either of the Centos rpms that we announced or
the FC8 2.6.25 rpms you found on our site. The patch in the 2.6.18
centos .src.rpm most probably won't apply (since most skb members
changed from pointers to offsets between 2.6.18 and 2.6.25). The patch
in the 2.6.25 tree is an ancient version of lisa and I'm not even sure
if it contains the xen tcp sum offload adjustments.
So, if pulling directly from our git tree, keep in mind that only the
2.6.29, 2.6.25 and 2.6.18 branches are up-to-date. We plan to backport
on 2.6.21, but the branch is not yet complete.
Should you have any more questions or need further instructions on
deploying lisa, please feel free to ask directly.
Thanks,
Radu Rendec
