How to define a second network in the hypervisor !!
Hi,
I have two PowerEdge T300 servers running as hypervisors servers for my RHEVM infraestructure. These servers has 2 lanics. In one of them has the segment 146.219.216.x (eth0) and this is named rhevm (network name) for the RHEVM console. Trough this lanic offers the conectivity for my all virtual machines.
The problem is when i want to use the second lanic (eth1) for configure a private network between 3 hosts (2 pcs and 1 virtual machine) with the segment 10.10.0.0, if run the ovirt-config-setup script, the option 3) configure network, aborts because says that the only way to configure extra networks is trough the rhevm console.
When i go to the rhevm console and select the hypervisor (hosts section), appears that has two physical lanics into the "Network interfaces" section, but the eth1 always appears with the link down. And the wizard for configure another network says that i have to install an extra lanics in the hypervisor server. What is that ??.
Exist some restrictions for use the free lanic (eth1) in the hypervisors ??.
Thank's in advance !!

The ovirt config script is just for setting the management network for the initial conctivity to take place.
I'm pasting the instruction from the quick start guide, please explain which step have failed for you and the exact message, and I'll try to assist.
In Red Hat Enterprise Virtualization Manager, network definition, type and function are encapsulated in a logical entity called a Logical Network.
To define logical networks in a cluster
-
Navigate to the Tree pane and click the Expand All button. Under System, click Default. On the results list, the Default data center displays.
-
On the details pane, select the Logical Networks subtab. This displays the existing logical networks. At this stage only the default rhevm network is listed.
-
Click New. The New Logical Network dialog displays.

Fill in the Name and Description fields, and tick the Assign Networks to Cluster(s) - Default checkbox to automatically add the Storage network to the Default data center. -
Click OK to create the new logical network.
-
Back on the Tree pane, click → → → . The Hosts tab displays a list of available hosts.
-
For each of your installed hosts, perform the following tasks:
-
Click on the host. On the details pane, select the Network Interfaces tab.
-
A list of network interfaces available for this host displays. One of them will already have the management network (rhevm) configured.

-
Select the interface on which to configure the Storage network and click the button. The Edit Network Interface dialog displays.

Configure the following options:
-
Under Network, select your newly created storage network.
-
Select the Static radio button. Enter the IP and Subnet Mask you have prepared as part of the prerequisites to this lab.
-
Tick the Save network configuration checkbox.

Need to look at the logs, can you open a case with support and refer them to this conversation?
Please use the log-collector and attach it's output to the ticket, that will shorten the response time
If this is the case then:
If the virtuale machine already exists - you can power it off and on the details pan ( bottom of the screen) go the the networks tab. From there you can add and delete virtual nics. While adding you'll be able to choose to which network to connect the virtual nic.
If you are creating new machine the you can do the same in the wizard that appears after you define the initial virtual machine properties. IE the configure networking option. The dialog should now allow you to select which network to use. The rhevm or the new one.
