I received an email from Alberto Gonzalez Rodriguez who created OpenXenCenter/OpenXenManager and is now working on OpenXenWebManager. Info to access the tool is:
steps to test are:
download from http://bit.ly/bres2U
uncompress: tar xvfz xenwebmanager_rev24_full.tar.gz cd xenwebmanager python frontend.py
and with a browser open http://localhost:8080 (or http://ip:8080) you need chrome or firefox (i prefer the first)
