Hi Lior I did managed to get the mgmt network tagged so now I can use the same interface for several networks. The thing now is that I also have two networks I use for iscsi that I'd like to be able to use in the same interface (not the mgmt one) in one of the hosts, but as this networks are in vlan1 untagged, I can't share the same interface. One of the things to try was marking the network as not VM (to see if I can share the interface in that scenario as suggested before), but I can't get the networks to be not-vm. What I'm doing as a work arround is to have the networks in a tagged vlan, but again, I can't have two networks in the same vlan :-(, thus, I'll have to configure two different vlans in my switchers just to be able to share the interface. This is not the greatest scenario as network layer tools in linux give all the needed options, but ovirt seems not to be able to use them yet. I was evaluating Proxmox prior to move to ovirt and they had this quite well implemented, I was able to do everything I needed with the network like with XEN (my actual virt platform) but cluster was not that easy to get going and I moved. Nothing is perfect :-) Anyway, I'll keep an eye on ovirt evolution to see if this gets better before I move to production. Thank you all for your help, any ideas are always welcome. Regards,
