After pulling the latest version it seems to work. If I move back to my
previous version it still works. Cannot reproduce the same behavior too.
So far the problem is solved for me.
Thanks
Marco

For my installation even the suggested modification (according
to [2])
by manually setting the ARCH type in
$ONE_LOCATION/etc/vmm_ssh/vmm_ssh_kvm.conf
to
OS = [boot = "hd", ARCH="x86_64"]
didn't worked and resulted in the same error in the vm.log
"No ARCH defined and no default provided
I can not reproduce this, can you re-check that you have pulled version
2.0.1, install it and that you are actually running that version
Thanks for the feedback
Cheers

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.

Hi.
Thanks for helping.
I have updated to the latest git-version but there is
still the
same
"Wrong Type!" message.
Perhaps it is really a problem about the occi syntax? Is
there a
way to
validate it? Is it possible to manually add some
debug-output to
the
ruby code: which file is responsible for parsing the xml
description?
Thanks
Marco

Hi,
The reason of that error is a typo in the common.erb
file. It
was fixed
in the last maintenance release. [1]
In the python code, you have to use the VM template
syntax [2],
because
you are interacting with the core using the xmlrpc api.
Hope this helps.
