Hi Simone,
<div class="">Hi all,<br class="">
<div class=""><br class="">
</div>
<div class="">As additional info, currently my network looks like below and I would like to switch from em1 to p4p1 exclusively, or perhaps use em1 as some sort of backup or for the management?</div>
<div class=""><br class="">
</div>
<div class="">2. Also, I’m not sure I understand fundamentally the differences between the different Network types (VM, Display, Migration). But that’s more for insotmation.</div>
<div class=""><br class="">
</div>
<div class="">Thank you for any pointers on this,</div>

Dear all,<br class="">
<br class="">
I have currently a data center with two clusters and each cluster had 1 host.<br class="">
<br class="">
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).<br class="">
<br class="">
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?<br class="">

<div class="">You can simply edit the network bindings from the engine:</div>

</div>
<div class=""><br class="">
</div>
<div class="">Is up to you to choose if you want just to use the 10 GbE NIC or if you prefer to create two distinct logical networks or an active-backup bond of the two interfaces.</div>

<br class="">
I prefer little downtime (eg only temp network loss), but a full downtime (shutting down) could be acceptable.<br class="">
<br class="">
Thank you for any pointers or starting points you could provide,<br class="">
<br class="">
Kind regards,<br class="">
<br class="">
