[one-users] [Beta 3.0] VNC "Failed to connect to server" problem (was: Sunstone-Server error on starting)

[Héctor Sanjuán]

Hi Christoph,

This is a bug. I have opened a ticket describing it in order to fix it [1].

Thank you very much for your valuable input. If you are in a hurry to
see the VNC working, I believe it may currently work when the VM is
deployed on localhost.

Best wishes,

Hector
