    initial v1  
    33It seems like there is a bug (???) with Intel PRO/1000 MT Desktop (82540EM), enabled GSO/TSO (by default for this NIC) and configured VLAN. It doesn't matter which "Attached to" type is used (Internal Network or Bridged Adapter).

    5 There is a simple scheme to reproduce this behavior.
    6 VM-1:
    7 Intel PRO/1000 MT Desktop (82540EM)

    2024Now, if you try to wget 10.10.10.20 from 10.10.10.10, VM-2 will be crashed and the host will be frozen completely a few moments later. Sometimes a window with an error appears (see error.png attachment).
