Hy guys,
after some headache I was able to use cloud-init via python-sdk (thanks to Juan), and I hope no one will fight anymore with them :D, so if you want I think it's better to document with a simple example it's use on web page available at:
http://www.ovirt.org/Features/Cloud-Init_Integration
below simple change that you can integrate on web page:
- fix api design example of usage for files xml, on the web page you can find:
... <files> <file> <name>/tmp/testFile1.txt</name> <content>temp content</content> <type>PLAINTEXT</type> </file> </files> ...
but on params.File there aren't any "type" parameter only "type_" so you can change xml with:
... <files> <file> <name>/tmp/testFile1.txt</name> <content>temp content</content> <type_>PLAINTEXT</type_> </file> </files> ...
This won't be correct, the correct XML tag name is "type", as in the example in the web page. It is not good idea to use this as a parmeter in python because it hides the "type" builtin function. That is why we renamed it to "type_".
- insert an example of using cloud-init via python-sdk (I hope java-sdk haven't big differences).
for this you can insert on web page an example of setting via cloud-init: hostname, reset root password and write a simple text file, and finally simple python code is:
... scontent = "write_files:\n- content: |\n #simple file\n PIPPO=\"ciao\"\n path: /etc/pippo.txt" action = params.Action( vm=params.VM( initialization=params.Initialization( cloud_init=params.CloudInit( host=params.Host(address="rheltest029"), users=params.Users( user=[params.User(user_name="root", password="pippolo")] ), files=params.Files( file=[params.File(name="/etc/pippo.txt", content=scontent, type_="PLAINTEXT")] ) ) ) ) ) vm.start( action ) ...
I think that you can edit that page and add this Python snippet. If you don't have an account for the wiki you can request one here: http://www.ovirt.org/Special:RequestAccount And if you want you can also submit a patch for the ovirt-engine-sdk project, adding your script in the (not yet existing) examples directory.
