I don't see any similarity to the console password "issue". While it's wise to avoid a password on a command line (you could read with ps), it's rather weird you cannot unplug a network cable from an "unstarted" VM. Simply, it seems this "feature" (you can find in virtualbox, for example) has not been designed. I am not using anything related to libvirt too. Thanks a lot.
