Not sure about through the UI, but this can be down with the default network scripts. I have 18 nodes in a cluster each with 2 nics. The nics are bonded together as bond0 and 3 vlans are used (well counting default) and one for management (vlan 1), one for private traffic (vlan 2), and public traffic (vlan 8). Ovirt picked up the network config without any issues and now I can assign VMs private and or public.

I feel like I have been bombarding this list the last few days, sorry! I have been looking at the different possible network configurations shown at http://www.ovirt.org/wiki/Vdsm_Network and trying to work out how to achieve the second topology ( bridge over vlan over nic ). I can see that it is possible to assign a logical network to a physical network on a node but how can you add more than one as this is a dropdown menu? My nodes have two NICs, one of these is for the management network but I could like to have a number of logical networks (with different VLAN tags) connected to the other NIC. Is this currently possible using the web UI?
Very simple 1. create your logical networks with vlan tags in the data centre 2. assign those networks to the relevant cluster Now, assuming we are going to assign network X with tag 100 and network Y with tag 200 to eth0 on a host: Edit eth0 on the host - assign network X to it see how eth0.100 gets created and the X network attached ot that tagged interface Edit eth0 again, assign network Y see how eth0.200 gets created and Y is attached repead for additional tagged networks

But I think we should provide a UI to the user and VDSM management API in the backend. Also, it is a quite a challenge to assign the VMs in different host to the same vlan. > > >> _______________________________________________ >> Users mailing list >> Users@ovirt.org >> http://lists.ovirt.org/mailman/listinfo/users >> -- Shu Ming<shuming@linux.vnet.ibm.com> IBM China Systems and Technology Laboratory

The settings I mentioned are talking about configuring __hosts__, not VMs. All the hosts in a cluster must have configurations to see all the logical networks assigned to that cluster. This way, a VM that uses a specific network can easily migrate between hosts without losing networking > > > > > > >> _______________________________________________ > >> Users mailing list > >> Users@ovirt.org > >> http://lists.ovirt.org/mailman/listinfo/users > >> > > > -- > Shu Ming<shuming@linux.vnet.ibm.com> > IBM China Systems and Technology Laboratory > > > -- Regards, Dan Yasny Red Hat Israel +972 9769 2280
