If I do "GET /compute" I get the same output as "GET /compute/".

Would you mind to send the $ONE_LOCATION/var/occi-server.log file and
the output of the following command, `onevm show 129 -x`? What
OpenNebula version are you using?

Try sending the following request "GET /compute" instead of "GET /compute/"?
