[Qemu-devel] [RFC PATCH 00/10] x-blockdev-create for qcow2
Posted by Kevin Wolf 8 years ago 
This series implements a minimal QMP command that allows to create an
image format on a given block node. The interface is still going to
change to some kind of an async command (possibly a block job), so I
prefixed x- for now.

At this point, I'm mostly interested in comments about
BlockdevCreateOptions in the schema, the .bdrv_co_create callback and
the way that legacy .bdrv_create is implemented in qcow2 now.

It looks to me as if we will have to keep .bdrv_create in addition to
the new .bdrv_co_create for a while in all drivers, where the
implementation of .bdrv_create would call .bdrv_co_create like this
series does it for qcow2. We'll only be able to drop the old interface
after deprecating and eventually removing all of the driver-specific
compatibility work that remains. The example of qcow2 shows that the
"translation" from old to new is managable, but there are a few
differences.

Kevin Wolf (10):
  block/qapi: Introduce BlockdevCreateOptions
  block/qapi: Add qcow2 create options to schema
  qcow2: Let qcow2_create() handle protocol layer
  qcow2: Pass BlockdevCreateOptions to qcow2_create2()
  qcow2: Use BlockdevRef in qcow2_create2()
  qcow2: Use QCryptoBlockCreateOptions in qcow2_create2()
  qcow2: Handle full/falloc preallocation in qcow2_create2()
  util: Add qemu_opts_to_qdict_filtered()
  qcow2: Use visitor for options in qcow2_create()
  block: x-blockdev-create QMP command

Peter? Eric? Any opinions so far?
