Re: [ovirt-users] multiple NICs VLAN ID conflict

I tried based on this url: (based on https://github.com/oVirt/vdsm/blob/master/vdsm_hooks/extra_ipv4_addrs/ext...) It seems to work ok, but the ovirt gui says the network is out of sync. So I can't add any more networks to that interface. :-(

If I try detaching the "custom" network I get an error: So obviously I'm missing something.
