    Hi

    It seems the network in my linux guest instance gets disconnected by Parallels. This happens when the screen is idle for about an hour. Note the the host computer (mac mini) is still reachable with ping and ssh. I have disabled all sleep function on the mac. Here are the logs (linux):

    Apr 15 23:18:00 ubuntu NetworkManager[610]: <info> (eth3): carrier now OFF (device state 100, deferring action for 4 seconds)
    Apr 15 23:18:00 ubuntu kernel: [22269.729410] e1000: eth3 NIC Link is Down


    When I connect to the mac host using Screen sharing from within Finder on another mac, the guest's network is restarted again:

    Apr 16 19:21:57 ubuntu NetworkManager[610]: <info> (eth3): carrier now ON (device state 20)
    Apr 16 19:21:57 ubuntu NetworkManager[610]: <info> (eth3): device state change: unavailable -> disconnected (reason 'carrier-changed') [20 30 40]
    Apr 16 19:21:57 ubuntu NetworkManager[610]: <info> Auto-activating connection 'Wired connection 1'.
    Apr 16 19:21:57 ubuntu NetworkManager[610]: <info> Activation (eth3) starting connection 'Wired connection 1'
    Apr 16 19:21:57 ubuntu NetworkManager[610]: <info> (eth3): device state change: disconnected -> prepare (reason 'none') [30 40 0]
    Apr 16 19:21:57 ubuntu NetworkManager[610]: <info> Activation (eth3) Stage 1 of 5 (Device Prepare) scheduled...
    ...

    Note that the linux instance is still running correctly, only the network gets disabled. It looks like someone unplugged the virtual cable. My physical screen is a hdtv connected to the mac mini with hdmi. Connecting with screen sharing wakes up the network in the guest.

    Is this expected behaviour and is it possible to fix somehow?
