[Bug 616064] Re: Broken networking in kvm guests

[Serge Hallyn]

Thanks for the info, Anthony.  The wireshark info failed to download for
me.  Could you attach it here?

My only guess ATM is that it is a bad interaction with the physical
switch or router to which eth3 is attached.  I'd ask you to try with
different hardware, but I see you're running production VMs on there.

Can you tell us exactly (names and models) what hardware is physically
involved in the network leading up to eth3?

Perhaps we can insert a logging layer 2 firewall between the switch and
eth3 to see what is going on there.  Do you have a spare machine with
two NICs which could be used for that?
