Hi,
I have a problem on a kvm hypervisor that I cannot explain. It appears 
that some traffic shows up in the interface monitoring in all of the 
guests on that hypervisor. We are not using broadcasts in any way and I 
see peaks of 100mbit for several minutes on all of these systems.

Does anybody have an idea what could cause this?

Regards,
   Dennis
