[libvirt-users] --persistent/--config confusion

Hi, I'm wondering how to attach a network device properly to a domain. According to the man page without "--config" a device created with "attach-device" will be added to the domain yet with "--config" it will only be added to the config and only be available after a restart of the guest. Is there no way to attach the device immediately *and* also make that change persistent? Regards, Dennis
