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. /# virsh domiflist --inactive 4a365b06-2597-4c17-8b44-dbb6953f9ced Interface Type Source Model MAC ------------------------------------------------------------------------ tap1eca5838-d5 bridge qbr1eca5838-d5 virtio fa:16:3e:9b:1c:fd tap20318b8b-b5 bridge qbr20318b8b-b5 virtio fa:16:3e:e1:bc:58 tap43bab93f-9a bridge qbr43bab93f-9a virtio fa:16:3e:8f:1e:23 tap2b059179-d9 bridge qbr2b059179-d9 virtio fa:16:3e:4e:f9:47 tap1ec7cd98-1d bridge qbr1ec7cd98-1d virtio fa:16:3e:21:5b:e0 tap46c2470d-08 bridge qbr46c2470d-08 virtio fa:16:3e:33:68:19 tap0a402f8f-05 bridge qbr0a402f8f-05 virtio fa:16:3e:89:dd:c4 tap4e737f62-e2 bridge qbr4e737f62-e2 virtio fa:16:3e:1d:2a:1c tap024ec465-22 bridge qbr024ec465-22 virtio fa:16:3e:16:1c:df tapd17d320e-a5 bridge qbrd17d320e-a5 virtio fa:16:3e:08:bf:9f tapcef35fc7-40 bridge qbrcef35fc7-40 virtio fa:16:3e:d6:5b:bf tap83de3d8e-b5 bridge qbr83de3d8e-b5 virtio fa:16:3e:69:21:90 tap660a3bb9-17 bridge qbr660a3bb9-17 virtio fa:16:3e:b7:33:d3 tap35d08903-93 bridge qbr35d08903-93 virtio fa:16:3e:15:ce:a3 tap8e63ed74-2a bridge qbr8e63ed74-2a virtio fa:16:3e:0a:3f:a8 tapb61b097d-e8 bridge qbrb61b097d-e8 virtio fa:16:3e:f0:f9:da tap189d75de-ee bridge qbr189d75de-ee virtio fa:16:3e:be:98:9d tap7108158a-fe bridge qbr7108158a-fe virtio fa:16:3e:a2:8b:e8 tap38015662-f2 bridge qbr38015662-f2 virtio fa:16:3e:d2:45:fe tapcc37cd83-fc bridge qbrcc37cd83-fc virtio fa:16:3e:64:26:f8 tapaf3ccc2a-0c bridge qbraf3ccc2a-0c virtio fa:16:3e:d2:0a:99 #
