[ovirt-users] How to add faster NIC to oVirt cluser / host?

Dear all, I have currently a data center with two clusters and each cluster had 1 host. On one of the hosts, I now enabled 10 GbE NIC called p4p1. Currently everything is going over a 1 GbE NIC called em1 (ovirtmgmt). My question now is, how I could add my 10 GbE NIC to the setup for instance to use for transferring data during transmissions to export domain or to simply replace the 1 GbE? I prefer little downtime (eg only temp network loss), but a full downtime (shutting down) could be acceptable. Thank you for any pointers or starting points you could provide, Kind regards, — Christophe
