Re: [Qemu-discuss] Virtually (dis)connect the ethernet cable

[Vincenzo Romano]

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.
