Nolan	c76f4952bb	Allow adjustment of http block device's readahead size, via a new ... ":readahead=###:" suffix. Signed-off-by: Nolan Leake <nolan <at> sigbus.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>	2009-07-09 16:06:40 -05:00
Christoph Hellwig	c16b5a2ca0	fully split aio_pool from BlockDriver ... Now that we have a separate aio pool structure we can remove those aio pool details from BlockDriver. Every driver supporting AIO now needs to declare a static AIOPool with the aiocb size and the cancellation method. This cleans up the current code considerably and will make it cleaner and more obvious to support two different aio implementations behind a single BlockDriver.

Alexander Graf	769ce76d0e	Add HTTP protocol using curl v6 ... Currently Qemu can read from posix I/O and NBD. This patch adds a third protocol to the game: HTTP. In certain situations it can be useful to access HTTP data directly, for example if you want to try out an http provided OS image, but don't know if you want to download it yet. Using this patch you can now try it on on the fly. Just use it like: qemu -cdrom http://host/path/my.iso Signed-off-by: Alexander Graf <agraf@suse.de>	2009-05-22 10:50:35 -05:00
