    I have running an Ubuntu KVM. It is going to be used as an Asterisk server and therefore has two interfaces so as to route SIP traffic over a seperate interface to a seperate network.
    They both work, but on the second interface i'm troubleshooting a packetloss issue. When looking at the interface with ethtool it reports it has an 1000mbit uplink to the switch.
    The switch it is connected to is in fact 100mbit (dumb/non-managed), so i'm trying to change the duplex setting of said interface on the server end to 100mbit full without autonegotion. (ethtool -s eth1 speed 100 duplex full autoneg off)
    This command indeed turns off the auto negotiation but seemingly does nothing with the Link speed. On the host I use the e1000 option as a network device.
    What could I be missing?

    Edit:

    The host server this KVM runs on did in fact negotiate 100mbit.
