Why are virtual interfaces created on top of the VM interface not getting network connectivity in OpenShift Virtualization?

Issue

• In OpenShift Virtualization, the VM interface is created on a Linux bridge. From the VM, a custom Windows software created a virtual interface with parent as the VM interface. The virtual interface have a different MAC address to that of VM interface MAC. This interface is unable to communicate with the network when configured with an IP address. The parent interface communication is working.
