Hi,
The attach patch adds VNC display support for QEMU. It does not use
libvncserver but was rather written from scratch. libvncserver is a
really neat project and I've used it in a number of other projects but I
think QEMU really requires a custom implementation.
First, to enable vnc support, you use the -vnc option like:
qemu -vnc 1
Where 1 is the first display (port 5901). This syntax may change in the
near future to support binding to a particular interface. It's very
useful to use an absolute mouse with VNC as the relative support is
quite poor. It may be useful to adapt the libvncserver patch's
calibration code here but I've not attempted to do that yet.
This patch is still experimental. I've tested it with RealVNC and
TightVNC under a variety of depths but I won't be suprised if there are
still problems. I only implement Raw, CopyRect, and Hextile encodings
too. Any sort of palette color mode or pixel format that QEMU doesn't
support will not work either.
One thing you may notice is that RealVNC has some issues with being
disconnected. This is because it likes to switch from 8bit to 32bit
depths automatically at startup. Unfortunately, there is a race
condition in the VNC protocol and since this implementation is
asynchronous, we seem to be much more prone to exposing this.
A short near-term TODO list is:
1) More testing
2) Support switching between monitor/serial
3) Support a better encoding (like TightEncoding or ZRLE)
4) Support a vnc password (and perhaps stuff like TLS)
Any feedback is greatly appreciated (especially with how it works with
clients I've not tested).
Regards,
Anthony Liguori
