Hello, I already asked similar question on May 2014. Then it started to work on CentOS 7.0 and 7.1. Now it fails again on 7.2. Setup is 2 network cards in a team, and then bridge between team and vnet0. The problem is, that I can ping KVM guest from host, but not from LAN. arping -I br0 192.168.0.200 ARPING 192.168.0.200 from 192.168.0.201 br0 Unicast reply from 192.168.0.200 [52:54:00:AB:50:C9] 0.869ms Unicast reply from 192.168.0.200 [52:54:00:AB:50:C9] 0.937ms ... ^CSent 8 probes (1 broadcast(s)) Received 8 response(s) arping -I eth1 192.168.0.200 ARPING 192.168.0.200 from 192.168.0.254 eth1 Unicast reply from 192.168.0.200 [52:54:00:AB:50:C9] 1.061ms ^CSent 5 probes (1 broadcast(s)) Received 1 response(s) Regards, Nerijus
