[Qemu-devel] [PATCH] Add HTTP protocol using curl v7 |
|
Date: |
Fri, 22 May 2009 16:57:02 +0200 |
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
In order to not reinvent the wheel, this patch uses libcurl.
Signed-off-by: Alexander Graf <address@hidden>
v2 changes:
- fix the segfault (yay!)
- implement AIO
v3 changes:
- remove synchronous API
- implement caching
v4 changes:
- enable other protocols (HTTPS, FTP, FTPS, TFTP, SFTP, SCP)
(I only tested FTP so far, but they _should_ work)
v5 changes:
- address Anthony's comments
- deactivate ssh protocols again
v6 changes:
- s/^I/ /g
- s/http/curl/g
v7 changes:
- add Signed-off-by again
