    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,
    Jon
