Any help is appreciated. > Whatever the issue is, it's unlikely in virt-manager. WRT wireless bridging, I was always under the impression it doesn't 'just work'. Some googling pointed to debian instructions here: https://wiki.debian.org/BridgeNetworkConnections#Bridging_with_a_wireless_NIC I'd recommend trying to get it working outside of libvirt/virt-manager, just using native distro config files. If you can get it working there, then we might be missing a step in libvirt or virt-manager. - Cole _______________________________________________ virt-tools-list mailing list virt-tools-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/virt-tools-list
