Hi Remy,
the only physical interface used is eth0 but I'm using vlans so the
interface connected to the bridge is eth0.8 and all the guests are
connected to this bridge as well. The output of ethtool -k for both eth0
and eth0.8 is:
Offload parameters for eth0.8:
rx-checksumming: on
tx-checksumming: on
scatter-gather: on
tcp-segmentation-offload: on
udp-fragmentation-offload: off
generic-segmentation-offload: on
generic-receive-offload: off
large-receive-offload: off
Regards,
Dennis

Hi Dennis,
Please post the KVM bridge topology and also the output of ethtool -k ethX (for each real nic).

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
