[Qemu-devel] [PATCH v4 00/37] x-blockdev-create for protocols and qcow2 |
Date: |
Wed, 7 Mar 2018 19:59:09 +0100 |
This series implements a minimal QMP command that allows to create an
image file on the protocol level or an image format on a given block
node.
Eventually, the interface is going to change to some kind of an async
command (possibly a (non-)block job), but that will require more work on
the job infrastructure first, so let's first QAPIfy image creation in
the block drivers. In this series, I'm going for a synchronous command
that is prefixed with x- for now.
This series converts qcow2 and all protocol drivers that allow an actual
image creation. This means that drivers which only check if the already
existing storage is good enough are not converted (e.g. host_device,
iscsi). The old behaviour was useful because 'qemu-img create' wants to
create both protocol and format layer, but with the separation in QMP,
you can just leave out the protocol layer creation when the device
already exists.
Please note that for some of the protocol drivers (gluster, rbd and
sheepdog) I don't have a test setup ready. For those, I only tested
with a fake server address to check that the option are parsed correctly
up to this point and an appropriate error is returned without crashing.
If you are a maintainer of one of these protocols and you are
interested in keeping image creation working for your protocol, you
probably want to test this series on a real setup and give me some
feedback. If you don't, I'll just merge the patches and hope that they
won't break anything.
v4:
- Rebased on top of a few conflicting series that have hit master
meanwhile
- qcow2: Renamed qcow2_create2() to qcow2_co_create() while resolving
the conflict from Paolo's series that renamed it to qcow2_co_create2()
- rbd: Further simplified qemu_rbd_mon_host() [Max]
