Hi Aryeh,

> bhyve(8) seems to bypass the standard stdin/out/err and send it's
> output directly to the TTY when handling guest console I/O.   I need

  For now, edirect bhyveload's output to /dev/null, and remove the 
",stdio" part of uart slot configuration.

  e.g. change "-S 10,uart,stdio" to "-S 10,uart"

  I should be doing some enhancements in this area in the near future 
that will make this a bit easier.

later,

Peter.
