[one-users] Network Connection and VNC not working

[Christoph Stich]

Hi Daniel,

at first, thanks for the reply and the support.

_1) network setup/problem:_
in general it seems to be resolved. I got it working and the vnet is 
bridged together with the physical interface.
vlan-tags are working, too.

The only remaining issue is: The IP leases from the vm-network seem only 
be set to the tty-linux. I'm able to ping and connect to it.
The other VMs, Ubuntu Server (from the Marketplace) are not pingable. Is 
the autoconfig of the interface not working for this?
_

__2) vnc setup / problem__:_
I added the output-file from "onetemplate show"

Kind Regards
Christoph
