Hi Simone,
Hi all,
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?
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.
Thank you for any pointers on this,

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?
You can simply edit the network bindings from the engine:
http://www.ovirt.org/OVirt_Administration_Guide#Editing_Host_Network_Interfaces_and_Assigning_Logical_Networks_to_Hosts
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.
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
