Can you also give us more detailed information, i.e. does this happen with hap only or also with shadow paging ? The changeset http://xenbits.xensource.com/staging/xen-unstable.hg/rev/e7afe98afd43 touches generic p2m code. The EPT code definitely needs an update in respect to get EPT-on-EPT with nested virtualization. Until further analysis is done, I can not say, there is no bug in the p2m changes and I can say as well that you might need Eddies EPT update patch as this may contain the fix you need.
