[Qemu-devel] [PATCH 2/2] Explicitly print out default vnc option in use

[Robert Ho <robert.hu@intel.com>]

If no display option defined in QEMU command line, and SDL is not
available, then it by default uses '-vnc localhost:0,to=99,id=default'.
This patch simply print out the default option parameters out, so that
user is aware of that.
