[Qemu-devel] [PATCH 0/4] Image Streaming API

[Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>]

These patches put in place the image streaming QMP/HMP commands and
documentation.  Image streaming itself is not implemented by this patch series
but the HMP/QMP commands that libvirt uses are implemented to return
NotSupported.

The Image Streaming API can be used to copy the contents of a backing file into
the image file while the guest is running.  The API is described on the wiki:
http://wiki.qemu.org/Features/LiveBlockMigration/ImageStreamingAPI

The point of this series is to commit QEMU to the API that we have worked out
with libvirt.  The QED Image Streaming series that I posted earlier provides an
implementation for the QED image format only.  I am currently working on a
generic block layer implementation so that any format with backing file support
can do image streaming.

For reference, the QED-specific implementation lives here:
