Ok that makes absolutely no sense to me now :-) Everytime I hit it I was
able to solve it eventually by setting 'tx off' on some combo of devices.
The RHEL-5 Dom0 kernel also already has the neccessary fixes in which is
even odder that it doesn't work for you.
So the question is where to proceed from here? I can tcpdump on the
bridge, peth and the domu host to see the errors.
Actually tcpdump showing errors does not neccessarily mean that there are
errors! If checksum offload is enabled, then you expect tcpdump to show
errors, because the checksum is not filled in by the OS - its left up to
the physical NIC. If you've turned 'tx off' on absolutely every device
then, tcpdump ought to show correct checksums though.
So here's the core of the problem. This is actually our koji builder.
When running:
koji list-tagged --quiet --latest --inherit f7-final
on lan, it takes about 10 seconds, when running it remote to another
machine it will run 12 minutes +.
