It's not the best way to read it, but google seems to have an html
version cached:
http://72.14.209.104/search?q=cache:VS3Scgtdi7sJ:www.cs.aau.dk/library/f

virtual+machine+monitor%22&hl=en&gl=us&ct=clnk&cd=1&client=firefox-a
The second part of their project also has a bit on shadow page tables:

I suspect they will fix their system and the full pdfs will come back
online soon.

The Potemkin paper also has a section on memory mgmt/shadow page
tables: http://www.cs.ucsd.edu/~savage/papers/Sosp05.pdf

The xen wiki has a little bit:

Might be more info here
http://www.cs.dartmouth.edu/~nihal/research_summer06_xen-mem.html ?

And maybe something of use here:
http://www.cs.wisc.edu/~remzi/Classes/736/Spring2005/Projects/Muru-Selva
/cs736-report.pdf

Note that I'm not the author of any of these and cannot really vouch
for their accuracy.  Also, they may be about older versions of xen --
their was recently a major update to the shadow page table code, so
that may not be reflected in these.  However, they will at least get
you started.
