[PATCH] VirtualBox headless VNC support by LibVNCServer

[Daisuke Aoyama]

Hi, all

I'm working with FreeNAS project and iSCSI target (ports/net/istgt).
This patch was written for using as add-on under FreeNAS.
FreeNAS is very small system which have no X11 and no useful develop 
tools/libs.
However, it is easy to use for beginners. I think it is useful if VituralBox 
is there.
If you don't want to install X11 same as FreeNAS, try this patch and use 
VBoxHeadless.

Before building, install "ports/net/libvncserver".
I recommend you backup virtualbox-ose directory before doing.
Uncheck QT4, X11, NLS by make config before extracting.

Howto apply the patch:
# cd /usr/ports/emulators/virtualbox-ose
# make config
# make extract
# patch -p < /path/to/VBox-VNC-Makefile.patch
# patch -p < /path/to/VBox-VNC-20100123.patch
# make

Note: if you already had applied the patch to Makefile, skip 
VBox-VNC-Makefile.patch.

Known issues/Limitations:
Does not support key lock such as CapsLock, NumLock.
Mouse cursor is not following as host cursor without the guest additions.
All features were not tested.

Regards,
Daisuke Aoyama
