Hey Rahmat - when an AIO-SX host is configured as a subcloud, the MGMT interface must be a physical interface. Assuming you are using the stx.3.0 release you can see this instruction here: https://docs.starlingx.io/deploy_install_guides/r3_release/bare_metal/aio_si... Step 4 speaks to this specifically.
