When I systemctl restart network, the bridge enslavements for the virtual interfaces (vi1, vi2, vnet0-vnet3) don't persist and I have to re-enslave each virtual interface. I am enslaving the the virtual interfaces with ip link set vnet3 master vb4.
How do I make the virtual interface bridge enslavements persist between service and machine restarts?

When I systemctl restart network, the bridge enslavements for the virtual interfaces (vi1, vi2, vnet0-vnet3) don't persist and I have to re-enslave each virtual interface. I am enslaving the the virtual interfaces with ip link set vnet3 master vb4.
How do I make the virtual interface bridge enslavements persist between service and machine restarts?
