Hi,
We've got copy-on-read and image streaming working in QED and before
going much further, I wanted to bounce some interfaces off of the
libvirt folks to make sure our final interface makes sense.
Here's the basic idea:
Today, you can
Sorry for commenting so late but it was Rosh Hashana over here.
Just to give you some pointers, sync_manager should also be zero config.
host id, timeouts etc are not in a config.
Host Id is decided when sync_manager starts, and timeouts are decided
upon lease creation so that all the

Why would it serialize all I/O operations? It's just like another

Because the block layer isn't re-entrant.
What you basically do is:
stream_step_three():
complete()
stream_step_two(offset, length):
bdrv_aio_readv(offset,

Ah. You can avoid the copy-on-read implementation in the block format
driver and do it completely in generic code.
Copy on read takes advantage of temporal locality. You wouldn't want to

Hi BK
Yes, I am running on windows. Is there any difference between the jar files
(linux and windows).
How can i compile the source for windows.
Thanks in advance
