When creating an image by sunstone-server, I find that the
SOURCE makes no sense. So I go to the source code both in Ruby and
opennebula, the SOURCE is only valid when using the PATH or SIZE(with
FSTYPE).
In my opinion, the whole image creation consists of four steps:
1. Sunstone-server sends "one.image.allocate" by using Ruby to
opennebula. The opennebula receives the calls and checks if the SOURCE
exists in parameters of the image template. If it does not exists,
opennebula assign a string to the SOURCE with the SHA1 digesting of
"uid:name", otherwise do nothing to the SOURCE. Then, inserts a image
record into the DB.
2. Then sunstone-server sends "one.image.info" to
opennebula to retrieve the initialized infomation by step 1, mainly the
value of SOURCE.
3. Suntone-server starts to judge the branches by PATH,
SOURCE, SIZE, FSTYPE and TYPE. When there only exists the SOURCE, it will
do nothing. (For example, if the PATH exists and SOURCE not exists, it will
do copy the PATH file to the SOURCE file path, and etc.)
4. If former
steps have no errors, sunstone-server sends "one.image.enable" to
opennebula, it just update the record in DB and do nothing about the
SOURCE. Otherwise, it sends "one.image.delete" to opennebula and delete the
record in DB.
So, if just specify the SOURCE to create an image, the
operation make no sense. So, I think the SOURCE input should be removed in
web pages of sunstone-server .
If I have mistakes, please send me the
error correction. Thanks. :-)
