Hi all,

I'm installing oVirt for the first time and I'm having some issues with the Networking.

Setup:

OS: CentOS 7 Mininal
3 Bare Metal Servers(1 for Engine, 2 for Nodes).

Network:

Nn Trunk Interfaces with VLANs and Bridges.

e.g.:

trunk.100, VLAN: 100, Bridge: vmbr100. IPV4 only.

I have already a VLAN for MGMNT, without DHCP Server(not needed for oVirt,
but explaining my setup).

Networking works as expected, I can ping/ssh each host without problems.

On the two nodes, I have a Interface named ovirtmgmt and dhcp...

Question 1: What kind of configuration can I use here? Can I set static IPs from VLAN MGMNT and put everything from oVirt on that VLAN? oVirt doens't have a Internal DHCP Server for Nodes, or?

Question 2: Should I leave oVirt to Setup it(ovirtmgmt Interface) for me?

Problems:

I configured the Engine with the IP 1.1.1.1, and I reach the web interface with https://FQDN( which is IP: 1.1.1.1)

But, when I add a Host to the Cluster, I have some errors:

"Host XXXX does not comply with the cluster Default networks, the following networks are missing on host: 'ovirtmgmt'"

Question 3: I saw that Engine tries to call dhclient and Setup an IP for it, but could I have static IPs? Where can I configure it?
