Some changes are needed in the econe code in order to support this
kind of URLs. I will open a ticket for this feature.

I have tested the following configuration and it works for me.

 * Apache configuration:
-------------------------------------------
<Location /ec2/>
ProxyPass          http://localhost:4567/
ProxyPassReverse   http://localhost:4567/
</Location>

 * econe configuration:
-------------------------------------------
# Host and port where econe server will run
:server: localhost
:port: 4567

# SSL proxy that serves the API (set if is being used)
:ssl_server: my-opennebula-host

 * Code changes (to add path support, in this case the path is
hardcoded "/ec2/":

Tested using OpenNebula git master branch and amazon-ec2 (0.9.17) gem

Hope this helps
