Start the Vivd guest and login > top right of screen secondary click Network Manager icon in the taskbar > Settings... > highlight WIred Connection 1 > Edit > tab IPv4 Settings > button Add > Address 192.168.56.3 > Netmask 255.255.255.0 > Gateway 192.168.56.1 > Save > click on the Network Manager icon in the taskbar and there should only be one entry for each interface. 4) What happens instead is there are two entries for Wired Connection 2, one that's connected, one that's disconnected, as per the attached screenshot: https://bugs.launchpad.net/ubuntu/+source/network-manager-applet/+bug/1402094/+attachment/4279934/+files/screenshot.png If one were to reverse the order of the adapters in vbox, one would see two entries for Wired Connection 2 in Network Connections.
bugzilla.gnome.org is being shut down in favor of a GitLab instance. We are closing all old bug reports and feature requests in GNOME Bugzilla which have not seen updates for a long time. If you still use NetworkManager and if you still see this bug / want this feature in a recent and supported version of NetworkManager, then please feel free to report it at https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/ Thank you for creating this report and we are sorry it could not be implemented (workforce and time is unfortunately limited).
