I was just going off of the behavior Matt described, that it was possible to boot with no network by leaving that out of the request. If the behavior already differs based on what networking backend is in use then we've put users in a bad spot, and IMO furthers my case for having explicit parameters in the request. I'm really not seeing how "--nic auto|none" is any harder than leaving all network related parameters off of the boot request, and it avoids potential confusion as to what will happen. > > Thanks, > doug > > > > On Feb 12, 2016, at 1:51 PM, Ed Leafe <e...@leafe.com> wrote: > > > > -----BEGIN PGP SIGNED MESSAGE----- > > Hash: SHA512 > > > > On 02/12/2016 02:41 PM, Andrew Laski wrote: > > > >>> I think if the point of the experience for this API is to be > >>> working out > >>>> of the box.
