libvirt users - Jan 2014 - Re: --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

Try combining both --config and --live on the same command line.

I tried --persistent and that seemed to have updated both the running 
system and the configuration.
