[ovirt-users]Re: Can ovirt-node support multiple network cards ？

I am unable to tell from your question what research you have done or what you have tried so far. Anyway, review this- https://ovirt.org/documentation/admin-guide/chap-Logical_Networks.html. Generally speaking, the checkbox for "Connect to physical network" should not be needed for your example. You most likely will need to set up VLANs when you create the logical network.
