I run Network Manager on almost all my systems, including this host. I did create a bridge in Network Manager, using these instructions as a basis: https://askubuntu.com/questions/62027/how-do-i-bridge-network-interfaces https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/8/html/configuring_and_managing_networking/configuring-an-ethernet-connection_configuring-and-managing-networking#configuring-an-ethernet-connection-by-using-nmtui_configuring-an-ethernet-connection To make this work, you specify one component of the bridge, the Ethernet IF, in NM. You specify the other device(s) in Virtual Machine Manager. Neither set of directions worked. So for now I'm giving this up as a bad job. I did find out that bridges don't work over some wifi connections for technical reasons. Due to the IEEE 802.11 standard which specifies the use of 3-address frames in Wi-Fi for the efficient use of airtime, you cannot configure a bridge over Wi-Fi networks operating in Ad-Hoc or Infrastructure modes. https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/8/html/configuring_and_managing_networking/configuring-a-network-bridge_configuring-and-managing-networking -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
