[one-users] OCCI syntax - [Wrong type! error]

[Strutz, Marco]

Hi.

I want to use OpenNebula for dynamic instantiation of virtual machines
by interfacing OCCI.
Unfortunately I'm facing some problems with the occi template definition
syntax.
Can you please help with the "Wrong type!" error?

 


the problem:
************
$ occi-compute create occiTemplate.xml
Wrong type!

 
--> "Wrong type!" is the response of the OCCIServer. 'occi-compute'
works fine.

 

the template
*************
$ cat occiTemplate.xml
<COMPUTE>
	<NAME>sl5.5</NAME>
	<STORAGE>
		<DISK image="3" dev="hda" />
	</STORAGE>
	<NETWORK>
		<NIC network="2" />
	</NETWORK>
	<INSTANCE_TYPE>
        		small
	</INSTANCE_TYPE>
	<CONTEXT>
		<HOSTNAME>
             		onevm
		</HOSTNAME>
		<FILES>
             		/srv/cloud/one/context/resources/software.tar.gz
/srv/cloud/one/context/resources/init.sh
		</FILES>
		<TARGET>
		             hdb
		</TARGET>
	</CONTEXT>
</COMPUTE>



 

 

same template but this time as xmlrpc request

$ python xmlrpcDeploy.py
xmlrpc-response.status  = False
