Hello Commnunity,
I saw an weird situation on a phytium machine (arm64 v8), after the following commands, I can still see the interface which should be successfully detached.
virsh # detach-interface 4a365b06-2597-4c17-8b44-dbb6953f9ced bridge --mac fa:16:3e:c5:62:40
Interface detached successfully
Future qmp commands shows, that a device hostnet23 exists but seems no front end device exists.
So what could be the problem? Thank you very much.
