[one-users] Network Connection and VNC not working

[Christoph Stich]

Dear All,

I got two problems at my opennebula/kvm environment.

_1) network setup_
in general the one frontend and kvm host are running and connected.
I can start instances of the ubuntu image (from marketplace).
But I'm not able to connect to the vm via the kvm-host.

At the kvm host I have a virbr0 with ip and dhcp server.
I created a network at the sunstone gui, which should use the virbr0.
I assigned an ip to the vm, but I'm not able to ping the vm.

I do not know what I'm doing wrong in this case.

_2) vnc setup_
The next issue has to do with vnc.
I created the ca and the server/client certs. Distributed the certs to 
all hosts.
I modified the libvirtd config / qemu config to use vnc and the certs. ( 
http://wiki.libvirt.org/page/VNCTLSSetup) 
<http://wiki.libvirt.org/page/VNCTLSSetup>
I installed the novnc at the one frontend.

When I know create a vm at open nebula and enable the graphics > vnc, 
the instance can not be created and fails with the following error:

I checked the permissions of folders and tested the setup without tls 
but the same error occured.
I checked the following guide: 
http://opennebula.org/documentation:rel3.6:sunstone#vnc_troubleshooting

But it did not help.

I already downloaded the following file: 
https://github.com/kanaka/websockify/downloads
and replaced the old websockify.

Thanks in advance for your time.

Regards
Chris
