This warning is telling you that you've created an emulated network but not plugged any emulated network devices in to it -- it's a legal configuration but almost certainly not what you want. The cause here is that you're trying to mix network configuration methods -- there is a 'new style' with "-netdev ...,id=foo" plus "-device ..,netdev=foo", and there is also an old style with "-net". Either will work (though -net is deprecated and the new style is preferred), but mixing the two as your command line does is going to result in confusion at best. Dropping the "-net user,smb=$HOME" will get rid of the unused network and the warning. thanks -- PMM
