[Qemu-devel] [PATCH 0/3] Support streaming to an intermediate layer

[Alberto Garcia]

Hello,

I added support to the Block Stream API for streaming to an
intermediate layer.

I followed the proposed API from the wiki, which simply adds an
additional 'top' parameter to block-stream specifying the image that
data is written to:

http://wiki.qemu.org/Features/Snapshots#Streaming_to_an_Intermediate_Layer_.5Bproposal.5D

I split the work in three patches, I think the code is pretty
straightforward and doesn't need much explanation, but feedback and
questions are welcome.

Regards,

Berto
