Hi Blair,

Unfortunately we don't have the resources to test the Boto client
application, but would be a very nice feature to support it. I suggest
starting with a glimpse of which functionality the OpenNebula
EC2-Query implementation supports (we just support a subset of the API
[1]). We don't add anything to the URL as Eucalyptus does.

Also, I suggest looking at the server logs
($ONE_LOCATION/var/econe-server.log) to check if the petition is being
received, it may shed some light as to why is failing.
