Hi Dan,
I'm with you about the VNC authentication.
But I still don't understand the logic behind assigning HVM displays.
Instead of clear "domU ID is the display number" (vncunused 0), the
Virtual Machine Manager assigns vncunused to 1 and then calculates the
5900+ port, I suppose depending on what port is not occupied (BTW
where exactly is this code in the source, please?).
Why is that? And how am I suppose to find out what that port number is
if I'd want to connect to a VMM-created vm manually with my vnc
client?
Thanks,
Glen

VNC authentication is an utter joke. It can be trivially brute forced
so exposing it on a public IP address is not a good idea, hence the
default is 127.0.0.1, though even that's not ideal because it is still
exposed to local users. Ultimately VNC needs to have SSL/TLS support
integrated into it to allow secure access over public network, which
is something I'm working on for QEMU...
Dan.
