Does the problem occur with the adapter assigned to the kvm guest or
the host?  I assume that you are running with the default behavior and
not with the boot arg "pci=pcie_bus_perf".  Can you get the dmesg
output (specifically the lines that have "Dev MPS") and lspci -vvv on
the host?  Is this an e1000e 4port adapter?

Thanks,
