    automation: include real-time view of the domU console log too
    
    Passthrough domU console log to the serial console in real time, not
    only after the test. First of all, this gives domU console also in case
    of test failure. But also, allows correlation between domU and dom0 or
    Xen messages.
    
    To avoid ambiguity, add log prefix with 'sed'.
