nova-xvpvncproxy is designed to work with a java client.  You want to use
nova-novncproxy, which is provided as part of the noVNC code from
http://github.com/cloudbuilders/noVNC.git.

More info here:
https://github.com/openstack/nova/blob/master/doc/source/runnova/vncconsole.rst

I'll be updating that doc today to incorporate some of the feedback from
this thread.
