Hi, I m using centos 7 in laptop and kvm as virtualization to run windows guest vm.Currently i m using NAT as default setting for guest vm, my internet is fine but can't resolve some domains and sites. So want to come on bridge. As per my understanding bridge can not work while device is managed by NetworkManager. Is there any utility or tool to use to scan wireless device in network and connect them as i want to stop to use Networkmanager to use laptop wireless interface as bridge for my guest vm. Thx Ben

Based on which reading? https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Networking_Guide/> Is there any utility or tool to use to scan wireless device in network and > connect them as i want to stop to use Networkmanager to use laptop wireless > interface as bridge for my guest vm.You cannot do what you want https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Networking_Guide/ch-Configure_Network_Bridging.html "Note that a bridge cannot be established over Wi-Fi networks operating in Ad-Hoc or Infrastructure modes. This is due to the IEEE 802.11 standard that specifies the use of 3-address frames in Wi-Fi for the efficient use of airtime."> Thx > BenAlexander

IIRC there's a reason mentioned in that guide and here's another one (answer 1): https://superuser.com/questions/597834/bridging-wifi-to-ethernet-on-ubuntu-not-working However there's a debian wiki entry that says it's possible using ebtables: https://wiki.debian.org/BridgeNetworkConnections#Bridging_with_a_wireless_NIC HTH, Patrick
