I don't understand why you would want this unless the ovirtnode itself was actually the router, wouldn't you want to only have an IP on the management network, and leave the rest of the VLANS blank so they depend on the router to route the traffic:

NIC1  -> ovirt-mgmt  - gateway set
NIC2  -> VLAN3, VLAN4, etc...

Viewing or Editing the Gateway for a Logical Network
Users can define the gateway, along with the IP address and subnet mask, for a logical network. This is necessary when multiple networks exist on a host and traffic should be routed through the specified network, rather than the default gateway.
If multiple networks exist on a host and the gateways are not defined, return traffic will be routed through the default gateway, which may not reach the intended destination. This would result in users being unable to ping the host.
oVirt handles multiple gateways automatically whenever an interface goes up or down.
