Hi René, I don´t have a second NIC, only a public on eth0.
So, if I understood correctly, Neutron is not part of oVirt, but needs to be installed a part. I need to use the All-in-one version of oVirt, so I need to install Neutron on this same host? Any additional advice? ----- Ursprüngliche Mail ----- Von: "René Koch" <[email protected]> An: "relaxibus" <[email protected]> CC: "Assaf Muller" <[email protected]>, [email protected] Gesendet: Montag, 10.

Here's a documentation on how to setup Neutron: http://www.ovirt.org/OVirt_Neutron_Integration Regards, René On 03/10/2014 02:43 PM, Jarno Puff wrote: > Hi Assaf, > > thanks for the answer. > > the data center where my server reside is a server4you.net, so all what you > get is a dedicated server and a public IP, thats it.
