All writes after the second will hang and ^C will return bash: echo: write error: Interrupted system call Same for "yes > /dev/vport0p1". The writes hang as soon as I exit nc on the host, and ^C exits cleanly to the shell. I think this patch is obvious. You might be seeing another bug that should be fixed separately.
