Hi, I am new to oVirt and trying to deploy a cluster to see whether we can move from VMWare to oVirt, but my first stopper is how to do a proper design for the infrastructure, how many networks do I need?, I have 2x10Gb SFP+ and 4x1Gb ethernet. For storage we have NFS coming from Netapp and ceph. Could someone point me in the right direction?

Hi, thanks for the info. So management network is used to deploy new images, but if I deploy the VM's from PXE server, I guess this is not needed, right? The storage network is clear. And then the entworks for the VM's I guess that are the networks with VLAN's, in my case, that will be used by the VM's. But, Which is the network for migrating VM's from one host to the other? Does it need to be non usable by the the VM's? Thanks.

Thanks for the tips, I have set up one NIC on VLAN 1 for storage, one NIC on VLAN 1 for Migration , 1 NIC on VLAN 1 for MGMT and one NIV on multiples VLANs for VM's. Does it make sense or I will have routing issues for having multiple interfaces on the same VLAN with different IP's?

Thanks.
