VNC and SDL/VGA simultaneously?

VNC and SDL/VGA simultaneously?

[Erik Rull]

Hi all,

is it possible to parameterize qemu in a way where the VNC port and the VGA 
output is available in parallel?

My system screen remains dark if I run it with the -vnc :0 option and vnc 
is unavailable when SDL/VGA is available.

Best regards,

Erik

Not really, though it should be possible to do it with some effort.

What's your use case?

I want to make remote support possble for a guest system that has only a 
local network connection to the host and has a graphical console running 
where the operator works on. (So "real" VNC is not available to the rest of 
the world)
It would also be okay if a switching between the VNC and the SDL/VGA would 
be possible at runtime so that the remote support can do the work and then 
switch back to the operators screen.

Best regards,

Erik

We tried before with both spice(QXL) and VNC enabled at the same time
for the same VM. It works a little bit, I mean VNC session can hold some
time. I use gtk-vnc and it looks like qemu vnc implementation sends some
special packets and cause gtk-vnc broken.

Hi all,

is there an update regarding simultaneous use of VNC and VGA output?

Thanks.

Best regards,

Erik
