What do you mean by "not like"? If v1 has an IP address attached to it,
you should be able to add this host to an oVirt cluster.

Once the host is added, you can use the GUI to seup more stuff on your host.

I would not recommend this, but you could define a libvirt network per
bridge to make it show in the web gui:
    <network>
      <name>vdsm-bridge1</name>
      <forward mode='bridge'/>
      <bridge name='bridge1' />
    </network>
