oVirt created bridge interfaces defaults to manual. As setting "DHCP" in oVirt I would assume that this would translate to "dhcp" in /etc/network/interfaces. But it always show 'manual'.
1) Setup a WR oVirt engine.
2) Setup a WR oVirt node and install it using the engine.
3) Create a new "Logical Network" (and attach it to the Cluster).
4) Use "Setup Host Networks" to assign the new Logical network to a physical interface on the node. Press the small "pen" icon to see that Boot Protocol is set to "DHCP" ('None' is default). Tick in "Save network configuration" and press OK.
5) Wait for the configuration to complete.
6) Check /etc/network/interfaces file on the node and see that the interface is set to manual, e.g.:
iface basenet inet dhcp
