Xen devel - Sep 2010 - How to setup the page sharing environment

Hi, milos/list, now I''m working on some code related to page sharing.
Are there any document/wiki that show how to setup the page sharing environment,
so that I can test my code?

Checking the code, I noticed the only tapdisk/blktap will use this page sharing
mechanism. I''m not sure HVM guest without PV driver can use blktap, so
does page sharing support HVM guest? Sorry that I''m not well on
tapdisk/blkdisk usage.

Thanks

I think there are *some* links about page sharing on Xen4.0 wiki page:
http://wiki.xensource.com/xenwiki/Xen4.0

It seems emails to Grzegorz.milos@citrix.com bounce back with "no such
mailbox",
so I guess he''s not working for Citrix anymore..

Any other contacts for page sharing patches?
