What's the output of attach-interface if you pass the --print-xml flag to it? What does the full live XML look like before and after the operation? Honestly this sounds like a guest OS issue rather than a bug in libvirt. Is any message produced in dmesg/journal as a consequence of the hotplug operation? -- Andrea Bolognani <[email protected]> Resistance is futile, you will be garbage collected.
