Hi,
On one hand the problem is the template that you are using. You are asking
for a disk linked to a storage resource and a nic linked to an existing
network, so that the template should be:
<COMPUTE>
<NAME>sl5.5</NAME>
<DISK>
<STORAGE href="http://yourserver/storage/3" />
<TARGET>hda</TARGET>
</DISK>
<NIC>
<NETWORK href="http://yourserver/network/2" />
</NIC>
<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>
For more information about OCCI usage [1], [2]
On the other hand there is a bug using xml templates that defines their
elements in more than one line, like this:
<COMPUTE>
<NAME>
foo
</NAME>
.....
</COMPUTE>
I have opened a ticket regarding this issue [3]
Hope this helps.
