Re: -drive if=none: can't we make this the default?

[Michael Tokarev]

Almost everyone mentions -blockdev as a replacement for -drive.

But I have to remind several issues with it:

1. While documentation has improved a lot, -blockdev is still mostly unknown
   to the masses.

2. -blockdev is just too verbose, one have to specify a lot of parameters just 
to
   do a simple thing which is solved with an extra parameter with -drive.
   Including various backing stores/chains for qcow2 files - this is terrible 
for
   using things manually from command line

3. -blockdev does not work with -snapshot

4. Something else I forgot while typing all the above :)

In my view, -blockdev is not a substitute for -drive, not at all, and it is
very user-unfriendly.  This is why -drive seems to be a good trade-off between
things like -hda (which is just too simplistic) and -blockdev which which is
way too verbose and lacks some automatic sugar like -snapshot.
