[libvirt-users] net interface direct - no IP communication between guest & host

hi everyone I wonder why, when I attach an interface like this: virsh # attach-interface --domain win10Ent --type direct --source nm-team --config --persistent --model virtio host cannot ip ping the guest and vice versa, yet guest can ping other nodes(outside of its host, connected via phys net via a switch) Would you know? I thought maybe routing on the host, so I did: $ route add -host 192.168.2.222 dev nm-team but to no avail. I wonder if it's lower layer, arp kernel bits? thanks, L.
