This is outside the scope of OVS; it's dependent on your hypervisor to create those virtual interfaces.  For example, XenServer will create VIFs in the hypervisor (e.g., vif1.0, vif2.0), which are then attached to the bridge (e.g., xenbr0).  I'm not familiar enough with VirtualBox to know what they expose.  Can you get VirtualBox to work using the standard Linux bridge?  A "brctl show" will show you which interfaces are connected to which bridges.  You should then be able to replicate that with appropriate "ovs-vsctl" commands.
