[ovirt-users] The he_fqdn proposed for the engine VM resolves on this host - error?

hi chaps, a newcomer here. I use cockpit to deploy hosted engine and I get this error/warning message: "The he_fqdn proposed for the engine VM resolves on this host" I should mention that if I remove the IP to which FQDN resolves off that iface(plain eth no vlans) then I get this: [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "The selected network interface is not valid"} All these errors seem bit too cryptic to me. Could you shed bit light on what is oVirt saying exactly and why it's not happy that way? many thanks, L.
