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.

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?
You can use 1G nic for the management network, but note that if you
want to upload and download images we use this network, so best have
a fast enough network for management.
You want separate network for storage (NFS/Ceph) - this your biggest
bottleneck.
Then you want a fast network for VMs. Migrating VMs from host to host
needs also fast network, but is not very common.
It depends also what the VMs are used for - database? desktops?
web servers? rendering nodes?
I guess you can learn from other users.
